Abstract

The longest-range part of the nuclear force from the one-pion exchange governs the energy dependence of the scattering amplitude in the near-threshold region and imposes correlations between the coefficients in the effective range expansion. These correlations may be regarded as low-energy theorems and are known to hold to a high accuracy in the neutron-proton S-3(1) partial wave. We generalize the low-energy theorems to the case of unphysical pion masses and provide results for the correlations between the coefficients in the effective range expansion in this partial wave for pion masses up to M-pi similar to 400 MeV. We discuss the implications of our findings for the available and upcoming lattice-quantum-chromodynamics simulations of two-nucleon observables.

Relations for low-energy coupling constants in baryon chiral perturbation theory derived from the chiral quark model

Jun Jiang, Shao-Zhou Jiang, Shi-Yuan Li, Yan-Rui Liu, Zong-Guo Si, Hong-Qian Wang

Summary: The symmetry of the quark model can establish relations between low-energy constants in the baryon chiral perturbation theory. By examining the correspondence between SU(2) and SU(3) descriptions at the quark level, relations between the low-energy constants in different orders of the chiral perturbation theory are found. Numerical analysis provides support for these relations.

Chiral effective Lagrangian for doubly charmed baryons up to O(q4)

Peng-Cheng Qiu, De-Liang Yao

Summary: The chiral effective meson-baryon Lagrangian for interactions between doubly charmed baryons and Goldstone bosons is constructed up to q(4) order. A total of 8, 32, and 218 linearly independent invariant monomials of O(q(2)), O(q(3)), and O(q(4)) are considered. This Lagrangian allows for studying the chiral dynamics and relevant phenomenology of doubly charmed baryons at complete one-loop level, and also includes a discussion on the nonrelativistic reduction of the Lagrangian for completeness.

Summary: We measured the strange axial coupling constant gsA using atmospheric neutrino data at KamLAND. This constant is a component of the axial form factor of the neutral-current quasielastic (NCQE) interaction. The value of gsA significantly affects the ratio of proton and neutron NCQE cross sections. KamLAND is well-suited for such measurements due to its ability to detect nucleon recoils with low-energy thresholds and measure neutron multiplicity with high efficiency.

Regularization in nonperturbative extensions of effective field theory

Curtis D. Abell, Derek B. Leinweber, Anthony W. Thomas, Jia-Jun Wu

Summary: The process of renormalization in nonperturbative Hamiltonian effective field theory (HEFT) is examined in the Delta-resonance scattering channel. HEFT provides a bridge between the infinite-volume scattering data of experiment and the finite-volume spectrum of energy eigenstates in lattice QCD, and examines the sensitivity of the finite-volume spectrum and state composition on the regulator.

Roy equation analyses of pp scatterings at unphysical pion masses

Xiong-Hui Cao, Qu-Zhi Li, Zhi-Hu Guo, Han-Qing Zheng

Summary: In this study, an extended Roy equation is used to investigate ππ scatterings at unphysical large pion masses, where σ becomes a bound state in one situation and remains a broad resonance in another case. The coupled integral equations at large pion masses are solved by considering lattice driving terms and Regge amplitudes as inputs. Using the solutions of Roy equations that satisfy unitarity, analyticity, and crossing symmetry, we make predictions for the phase shifts with IJ = 00, 11, and 20 in the elastic energy region. We then analytically continue into the complex s plane to search for various poles, all of which lie within the valid domain of the Roy equation. This is the first time that lattice data at unphysical large pion masses are analyzed using the rigorous Roy equation method.

Phase shifts of the light pseudoscalar meson and heavy meson scattering in heavy meson chiral perturbation theory

Bo-Lin Huang, Zi-Yang Lin, Kan Chen, Shi-Lin Zhu

Summary: We calculate the complete T matrices of elastic light pseudoscalar meson and heavy meson scattering to the third order in heavy meson chiral perturbation theory. We determine the low-energy constants by fitting the phase shifts and scattering lengths from lattice QCD simulations simultaneously, and predict the phase shifts at the physical meson masses. The strong phase shifts in various channels suggest the presence of bound states or resonances, including the well-known exotic state D-s0*(2317).

Flavor nonsinglet parton distribution functions from lattice QCD at physical quark masses via the pseudodistribution approach

Manjunath Bhat, Krzysztof Cichy, Martha Constantinou, Aurora Scapellato

Summary: This study provides a determination of the flavor nonsinglet (u - d) unpolarized parton distribution function using the nonperturbative formulation of QCD on the lattice, making the first attempt at using Radyushkin's pseudodistribution approach directly at the physical point. Extracted coordinate-space matrix elements are used to find the relevant physical Ioffe time distributions, resolving the full Bjorken-x dependence of PDFs with various reconstruction methods to handle ill-conditioned inverse problems encountered with discrete lattice data.

Summary: The interaction between Lambda and Sigma hyperons with nucleons is influenced by coupled-channel dynamics, and the coupling strength of the N Sigma <-> N Lambda processes is crucial in determining the N Lambda interaction. This study presents precise measurements on the interaction of p Lambda pairs and observes the direct experimental evidence of the N Sigma <-> N Lambda coupled channel in the p Lambda system. The findings have implications for the nuclear equation of state and the presence of hyperons inside neutron stars.

Summary: This article reports the transverse single-spin asymmetries of charged hadrons in different collision processes as a function of transverse momentum and Feynman-x. Nonzero asymmetry is observed for positively charged hadrons in forward rapidity in p(up arrow)+ p collisions, while smaller asymmetries are found in p(up arrow)+ Al and p(up arrow)+ Au collisions. This finding provides new opportunities to study the origin of transverse single-spin asymmetries and nuclear effects in p thorn A collisions.

Definition of Local Spatial Densities in Hadrons

E. Epelbaum, J. Gegelia, N. Lange, U-G Meissner, M. Polyakov

Summary: The matrix element of a local operator between hadronic states is used to define the associated spatial density. The charge density of a spinless particle is studied as an example, clarifying its relationship to the electric form factor. The results provide an unconventional interpretation of the spatial densities of local operators and their moments.

Renormalization of nuclear chiral effective field theory with nonperturbative leading-order interactions

A. M. Gasparyan, E. Epelbaum

Summary: We extend the renormalizability study of chiral effective field theory with a finite cutoff to nucleon-nucleon scattering, considering nonperturbative effects. The nucleon-nucleon interaction is expanded up to next-to-leading order, with the leading-order interaction treated nonperturbatively. New features related to the renormalization of the effective field theory are revealed, including more stringent constraints on the leading-order potential to ensure renormalizability and correct power counting for the next-to-leading-order amplitude. Numerical analysis of several partial waves in nucleon-nucleon scattering, 3P0, 3S1-3D1, and 1S0, is conducted to illustrate the theoretical findings, discussing cutoff dependence and convergence of the chiral expansion for these channels.

Emergence of heavy quark spin symmetry breaking in heavy quarkonium decays

V. Baru, E. Epelbaum, A. A. Filin, C. Hanhart, A. V. Nefediev

Summary: Heavy-quark spin symmetry applies to the direct decay of heavy quarkonia, but can be overcome in the presence of multiquark intermediate states. The violation of HQSS can be balanced by the narrowness of the intermediate states, resulting in equal transition strengths into final states with different total heavy quark spins. Spin symmetry is restored when the mass of a heavy quark becomes infinite.

Pairing properties of semilocal coordinate- and momentum-space regularized chiral interactions

P. Yin, X. L. Shang, J. N. Hu, J. Y. Fu, E. Epelbaum, W. Zuo

Summary: We investigate the pairing properties of state-of-the-art semilocal coordinate-space and semilocal momentum-space regularized chiral interactions. We find weak regulator dependence and robust convergence in the 3SD1 and 1S0 pairing gaps, while chaotic behavior is observed for the 3PF2 results. In addition, discrepancies between the chiral interactions and the Av18 potential in the 3SD1 and 3PF2 channels suggest the need for further constraints on the nucleon-nucleon interactions in these channels at high energies. Furthermore, the different tensor force effects of the chiral interactions and the Av18 potential for the 3SD1 and 3PF2 pairing gaps indicate distinct tensor components in these interactions.

Gravitational form factors of the delta resonance in chiral EFT

H. Alharazin, E. Epelbaum, J. Gegelia, U-G Meissner, B-D Sun

Summary: The leading one-loop corrections to the gravitational form factors of the delta resonance are calculated using chiral effective field theory. The contributions to the energy-momentum tensor and renormalization of low-energy constants are determined. Static quantities are obtained through small scale expansion, and the real and imaginary parts of the gravitational form factors are numerically calculated.

Pion photoproduction in chiral perturbation theory with explicit treatment of the ?(1232) resonance

N. Rijneveen, A. M. Gasparyan, H. Krebs, E. Epelbaum

Summary: In this article, we study the reaction of pion photoproduction on the nucleon using chiral perturbation theory. We present results using both the covariant approach and the heavy-baryon scheme, and compare them to experimental data using Bayesian methods to estimate theoretical truncation errors. We find that the explicit treatment of the delta(1232) resonance significantly improves the description of the reaction.

Nucleon-nucleon interaction in chiral effective field theory with a finite cutoff: Explicit perturbative renormalization at next-to-leading order

A. M. Gasparyan, E. Epelbaum

Summary: In this study, we investigate two-nucleon scattering using chiral effective field theory with a finite cutoff to next-to-leading order in the chiral expansion. We propose a scheme where the contributions of the lowest-order interaction to the scattering amplitude are summed up to an arbitrary order, while the corrections beyond leading order are iterated only once. We consider a general form of the regulator for the leading-order potential, including local and non-local structures. The main objective is to address the formal aspects of renormalizability within this scheme, and we provide a rigorous proof that power-counting breaking terms can be absorbed into the renormalization of low energy constants. We also demonstrate that the cutoff dependence of the scattering amplitude can be reduced by perturbatively subtracting the regulator artifacts at next-to-leading order. The numerical results confirm the applicability of our scheme for nucleon-nucleon scattering.
