Abstract

We study the B meson spectroscopy allowing the mixture of conventional P wave quark-antiquark states and four-quark components. A similar picture was used to describe the new D-J and D-sJ open-charm mesons. The four-quark components shift the masses of some positive parity B-sJ states below their corresponding isospin preserving two-meson threshold and therefore they are expected to be narrow. Electromagnetic decay widths are analyzed.

Coulomb effects in the decays Υ(4S) → B(B)over-bar

A. Milstein, S. G. Salnikov

Summary: A simple solvable model was proposed to describe the decays Upsilon(4S) -> B-0(B) over bar (0) and Upsilon(4S) -> B+B-, with predictions matching experimental data. Coulomb effects in the spectra of these decays were analyzed, revealing the lack of fulfillment of the factorization assumption for Coulomb effects. The Coulomb interaction caused differences in peak positions and heights between charged and neutral modes, resulting in a nontrivial energy-dependent ratio of decay probabilities.

Shedding light on the X(3930) and X(3960) states with the B-→ K- J/ψω reaction

L. M. Abreu, M. Albaladejo, A. Feijoo, E. Oset, J. Nieves

Summary: We have studied the contribution of the state X(3930) to the B- -> K- J/psi omega decay, which originates from the interaction of the D ($) over bar and D-s(+) D ($) over bar (s) channels. Our goal is to determine if the X(3930) state observed in the D+ D- channel is the same as the X(3960) resonance claimed by the LHCb Collaboration from a peak in the D-s(+) D s mass distribution around threshold. We predict that a clear signal should be seen around 3930 MeV in the J/psi omega mass distribution, and the absence of a resonance signal at 3960 MeV would support the hypothesis that the near-threshold peaking structure is only a manifestation of a resonance below threshold.

Charged current electroproduction of a charmed meson at an electron-ion collider

B. Pire, L. Szymanowski, J. Wagner

Summary: In this study, we calculated the amplitude for exclusive electroweak production of pseudoscalar Ds or vector Ds charmed strange meson on an unpolarized nucleon in leading order alpha s. We utilized the collinear QCD approach where generalized gluon distributions factorize from perturbatively calculable coefficient functions. It was shown that this process could potentially be studied at future electron-ion colliders.

A novel observable for CP violation in multi-body decays and its application potential to charm and beauty meson decays

Zhen-Hua Zhang

Summary: The FBI-CPA is a novel observable for measuring CP asymmetry in multi-body decays of heavy mesons. It can isolate the CP asymmetry associated with interference of different wave amplitudes and effectively double the statistics compared to conventional methods. It is suggested to perform measurements of FBI-CPA in three-body decay channels of charm and beauty mesons.

Impact of a nonuniversal Z' on the B → K()l+l- and B → K()ν(ν)over-bar processes

A. V. Bednyakov, A. I. Mukhaeva

Summary: In this study, we investigate the new physics effects in semileptonic flavour changing neutral current processes within an anomaly-free supersymmetric extension of the standard model. The model features a nondiagonal coupling structure between the Z' vector field and fermions, which is parametrized by new physics parameters in addition to the mixing matrices for quarks and leptons in the standard model. We analyze the dependence of observables such as B -> K-(*())nu(nu) rates and CP-odd angular observables in B -> K*ll decays on these parameters, as well as correlations between the predicted observables.

Summary: The LHCb experiment searched for the rare hadronic decay Bs(0) -> p(p) over bar using proton-proton collision data, and found evidence for the B-0 -> p (p) over bar decay mode. The branching fraction for this decay was determined, and an upper limit was set for the Bs(0) -> p (p) over bar decay.

Hadronic loop effects to excited scalar charmed mesons revisited

Mohammad H. Alhakami, Numa A. Althubiti, Nwuyer A. Al-shammari

Summary: We re-examine the hadronic loop effects on the masses of D* (0) and D*(s0) calculated in quark models in the framework of heavy meson chiral perturbation theory (HMCHPT). Unlike previous approaches, ours reproduces the observed scalar charm states reported by the Particle Data Group (PDG). We show why previous approaches of using HMCHPT in studying mass shift effects due to chiral loops gave unsatisfactory results.

Methods for high-precision determinations of radiative-leptonic decay form factors using lattice QCD

Davide Giusti, Christopher F. Kane, Christoph Lehner, Stefan Meinel, Amarjit Soni

Summary: This study presents lattice-QCD methods for determining form factors in radiative-leptonic decays of pseudoscalar mesons. Numerical results for the decay D+s -> e+ nu gamma are provided. The study focuses on controlling systematic errors caused by unwanted excited states and exponentials in the calculation. Different methods, such as the 3D and 4D sequential propagators, are analyzed individually and in combination to improve control over these errors. The optimal combination of methods yields accurate results for the form factors in the entire kinematic range.

Composite flavon-Higgs models

Yi Chung

Summary: The paragraph discusses a composite Higgs model based on the SU(6)/Sp(6) coset, with an U(1) subgroup of Sp(6) identified as the flavor symmetry. By introducing a light flavon, it generates the mass hierarchy between the top and bottom quarks and provides a testable model for the origin of flavor hierarchy. The direct search of additional scalar bosons can be conducted in HL-LHC and future hadron colliders.

Minimal Explanation of Flavor Anomalies: B-Meson Decays, Muon Magnetic Moment, and the Cabibbo Angle

David Marzocca, Sokratis Trifinopoulos

Summary: Significant deviations from the standard model are observed in semileptonic charged and neutral-current B decays, the muon magnetic moment, and the extraction of the Cabibbo angle, pointing towards a coherent pattern of new physics effects induced by two scalar mediators. This framework provides the most minimal explanation to the mentioned anomalies while being consistent with all other phenomenological constraints.

Summary: This paper discusses the potential of measuring the B-c -> tau nu(tau) process at the proposed CEPC, with results showing high signal strength accuracy during Z pole operation. Future determination of the total B-c yield at the O(1%) level may also lead to more precise measurements of |V-cb|.

A study of Type B uncertainties associated with the photoelectric effect in low-energy Monte Carlo simulations

Summary: This study estimated the Type B uncertainties in absorbed-dose calculations arising from the implementation of low-energy photon cross-sections in three state-of-the-art Monte Carlo codes. The results showed that there are significant uncertainties in absorbed dose and photon-fluence spectra across different energy ranges due to the variations in cross-section implementations.

Clues about the Nature of Multiquark States

Humberto Garcilazo, Alfredo Valcarce

Summary: In this study, a comprehensive investigation into the decay width of multiquark states using a coupled-channel approach was conducted, revealing that the decay width can offer detailed information about the nature of resonances. The symmetrical situation between meson- and baryon-like multiquarks was emphasized, and the existence of narrow resonances with large phase spaces was taken into account. The research also indicated that the decay width of multiquark states is determined by the mass difference with the formation channel, with tighter bindings leading to larger decay widths.

(I, JP) = (1,1/2+) SNN Quasibound State

Humberto Garcilazo, Alfredo Valcarce

Summary: JLab has found indications of a possible sigma NN resonance at (3.14 +/- 0.84) -i(2.28 +/- 1.2) MeV. Using previous models, we have derived theoretical evidence of a quasibound state in the lambda NN - sigma NN system, which is in reasonable agreement with experimental findings.

Effect of relativistic kinematics on the stability of multiquarks

Jean-Marc Richard, Alfredo Valcarce, Javier Vijande

Summary: The study shows that relativistic corrections to the kinetic energy can lower the binding energy of multiquark states, requiring a parameter retuning of the model. Tetraquarks with double heavy flavor become more stable at higher ratios of heavy to light quark masses, while all-heavy tetraquarks remain unstable when a relativistic form of kinetic energy is adopted.
