Abstract

Masses, widths and photocouplings of baryon resonances are determined in a coupled-channel partial-wave analysis of a large variety of data. The Bonn-Gatchina partial-wave formalism is extended to include a decomposition of t and u exchange amplitudes into individual partial waves. The multipole transition amplitudes for gamma p -> p pi(0) and gamma p -> n pi(+) are given and compared to results from other analyses.

Julich-Bonn-Washington model for pion electroproduction multipoles

M. Mai, M. Doering, C. Granados, H. Haberzettl, Ulf-G Meissner, D. Roenchen, I Strakovsky, R. Workman

Summary: The study analyzes pion electroproduction off the proton in a new framework based on a general parametrization of transition amplitudes, incorporating constraints from gauge invariance and threshold behavior. Large-scale fits were performed, resulting in a set of solutions with chi(2)(dof) = 1.69-1.81, allowing for the assessment of the systematic uncertainty of the approach.

Coupled-channels analysis of pion and η electroproduction within the Julich-Bonn-Washington model

M. Mai, M. Doering, C. Granados, H. Haberzettl, J. Hergenrather, Ulf-G Meissner, D. Roenchen, I Strakovsky, R. Workman

Summary: In this study, the electroproduction data of pion and eta particles are jointly analyzed for the first time up to a center-of-mass energy of 1.6 GeV. The results provide insights into the determination of resonance amplitudes in the near-threshold region. It is found that some amplitudes can be well determined while others require data over a wider energy range.

Ridge regression for minimizing the couplings of hyperon resonances in K+A photoproduction

D. Petrellis, D. Skoupil

Summary: We employed the isobar model and utilized the recent CLAS polarization data to investigate the K+A photoproduction process. By applying Ridge regression, a penalty term was added to enhance the X2 minimization and reduce the previously obtained large values of couplings. This resulted in a more robust model with hyperon couplings reduced to more physically reasonable values. This model allows us to extract valuable information on the K+A photoproduction background and the role of various hyperon resonances, with the set of nucleon resonances remaining the same as in previous fits but with potentially changed roles due to different couplings obtained in the present fit.

Charm-baryon semileptonic decays and the strange Λ* resonances: New insights from lattice QCD

Stefan Meinel, Gumaro Rendon

Summary: Understanding the properties of strange Lambda* baryon resonances is a long-standing and fascinating problem. By computing the form factors, we can predict the decay rates and angular observables of Lambda(c) decaying to Lambda*(1520). Furthermore, by combining experimental measurements and theoretical predictions, we obtain an upper limit on the decay rates of Lambda(c) to other semipositronic final states.

Single-energy partial-wave analysis for pion photoproduction with fixed-t analyticity

H. Osmanovic, M. Hadzimehmedovic, R. Omerovic, J. Stahov, V Kashevarov, M. Ostrick, L. Tiator, A. Svarc

Summary: Experimental data for pion photoproduction were used to perform a single-energy partial-wave analysis with minimal model dependence, showing that partial wave amplitudes obtained through this procedure exhibit only a minimal dependence on the initial model assumptions. The analysis was conducted in full isospin and enforced the Watson theorem for energies below W = 1.3 GeV.

QCD analysis of near-threshold photon-proton production of heavy quarkonium

Yuxun Guo, Xiangdong Ji, Yizhuang Liu

Summary: The study focuses on the near-threshold photo or electroproduction of heavy vector quarkonium off the proton, showing that the threshold kinematics has a large skewness parameter xi, leading to the dominance of the spin2 contribution. Threshold production data are useful to extract gluonic gravitational form factors and study gluonic contributions to various properties in the proton. The research uses recent GlueX data on J/Psi photoproduction to demonstrate the potential physics impact of high-precision data from future Jefferson Laboratory 12 GeV and Electron-Ion Collider physics program.

Summary: We present a new measurement of the beam-spin asymmetry, Sigma, for the (gamma) over right arrown -> K+Sigma(-) reaction using quasi-free neutrons in a liquid-deuterium target. The dataset includes previously unmeasured photon energy and angular ranges, providing new constraints for partial wave analyses. The experimental data were obtained using the CLAS detector at JLab, and predictions from an isobar model confirm the sensitivity to specific resonances. The inclusion of this data in partial-wave analyses leads to significant changes in gamma-n couplings of resonances with small branching ratios to the pi N channel.

Singlet-octet-glueball mixing of scalar mesons

E. Klempt, A. Sarantsev

Summary: The mixing angles between scalar isoscalar resonances and a scalar glueball are determined from their decays into two pseudoscalar mesons. Results show that a small glueball component is admitted by some scalar isoscalar resonances, while significant glueball fractions are required for other resonances. The summation of all observed glueball fractions yields approximately 78%.

Study of the Production of Positively Charged Pions in Proton-Proton Collisions in the Range of Primary Momenta between 1345 and 1536 MeV/c

V. V. Sarantsev, S. G. Sherman, A. Sarantsev

Summary: This study presents the differential cross sections obtained for the reaction pp -> pn pi(+) at different incident proton momenta. The measurements were performed using a hydrogen-filled bubble chamber and compared with the predictions of the one-pion-exchange model. A partial-wave analysis was conducted to determine the contributions of various partial waves to the process of pion production in the energy region being studied.

Role of Martensite-Austenite Component of Bainitic Structure in Formation of Properties of Pipe Steel. 1. Effect of Parameters of TMT

N. G. Kolbasnikov, S. A. Kuzin, V. S. Teteryatnikov, N. Zhukov, R. R. Adigamov, M. S. Sakharov, M. A. Matveev

Summary: The effect of hot rolling and controlled cooling parameters on the formation of the martensite-austenite component in bainitic and ferritic-bainitic structures of K60 pipe steel was studied. Experimental results showed that the volume fraction of the martensite-austenite component varied from 0.5% to 8% depending on the parameters of the thermomechanical treatment. The accumulated strain was found to play a dominant role in the formation of martensite-austenite particles and the determination of the acicular ferrite fraction.

Search for the tensor glueball

E. Klempt, K. Nikonov, A. Sarantsev, I Denisenko

Summary: The tensor glueball is investigated in BESIII data by studying radiative J/psi decays into pi(0)pi(0) and KsKs. An enhancement in the pi pi invariant mass distribution is observed, which can be explained by either a pole or three phi phi resonances, suggesting the presence of one, two, or three glueballs. It is also speculated that high-mass tensor mesons may possess both q (q) over bar and glueball components.

Summary: Using the BESIII detector, (10 087 +/- 44) x 10(6) J/psi events were collected to study the radiative hyperon decay Sigma(+) -> p gamma for the first time in an electron-positron collider experiment. The absolute branching fraction is measured to be (0.996 +/- 0.021(stat) +/- 0.018(syst)) x 10(-3), which deviates by 4.2 standard deviations from the world average value. The decay asymmetry parameter is determined to be -0.652 +/- 0.056(stat) +/- 0.020(syst), and these measurements represent the most precise values to date with improved accuracies of 78% and 34% for the branching fraction and decay asymmetry parameter, respectively.

Summary: The behavior of low-carbon pipe steel containing 2 and 6 vol.% martensitic-austenitic component in the structure is studied under step forming, expanding and unbending of the pipe using the method of finite-element simulation. The effect of martensitic transformation in the MA-component on the ductility of the steel after processing and unbending of the pipe depending on the volume fraction of the MA-particles in the structure and on the test conditions (the direction of cutting of the samples and the stresses at the start of martensitic transformation) is studied. It is shown that the presence of untransformed austenite in the MA-component can restore partially the ductility of the steel lost due to the plastic deformation during processing of the pipe.

Summary: This research extends the understanding of the thermal and deformation stability of untransformed austenite in the martensitic-austenitic component of low-carbon steel bainitic structure, through experimental and theoretical studies. The analysis of compressive hydrostatic stresses during dilatation provides the relationships to determine the temperature at which martensitic transformation begins in the MA-component, as well as the level of deformation caused by strain-induced martensitic transformation.
