The a0(980) in the single Cabibbo-suppressed process Λc → π0ηp
In this work, we have investigated the Cabibbo-suppressed process Λc→π0ηp, by taking into account the intermediate scalar state a0(980), which could be dynamically generated from the S-wave pseudoscalar-pseudoscalar interaction within the chiral unitary ...

WW Scattering Parameters via Pseudoscalar Phase Shifts [PDF]
Using domain-wall lattice simulations, we study pseudoscalar-pseudoscalar scattering in the maximal isospin channel for an SU(3) gauge theory with two and six fermion flavors in the fundamental representation.

Decay of charmonium states into a scalar and a pseudoscalar glueball
In the framework of a chiral symmetric model, we expand a U(4)R × U(4)L symmetric linear sigma model with (axial-)vector mesons by including a dilaton field, a scalar glueball, and the pseudoscalar glueball.

The linear and nonlinear (chir)optical properties of four oligoamide foldamers with different donor groups are studied by means of time‐dependent density functional theory calculations. It is shown that stronger donors yield larger hyperpolarizabilities due to low‐lying charge–transfer states. The agreement with the experiments concerning the key bands

Exact formula of the spectrum of the pseudoscalar octet
Non-perturbative proof is presented of a generalized version of Goldstone theorem, where the Lagrangian conserves an approximate SU(3) chiral symmetry, that both quark masses and electromagnetism make contributions to the masses of spinless particles of ...

Strong decay constants of heavy tensor mesons in light cone QCD sum rules [PDF]
Strong decay constants of the heavy tensor to heavy pseudoscalar (vector) and light pseudoscalar mesons are estimated within the light cone QCD sum rules.

This review connects chiroptical spectroscopy, asymmetric catalysis, and spintronics, revealing how chirality influences the interactions of matter with light, charge, and spin. Across diverse systems, remarkable chiroptical effects emerge, showing among others that high efficiencies can arise without absolute enantiopurity, and that functionality is ...

Radiative Decay Widths of Ground and Excited States of Vector Charmonium and Bottomonium
We study the radiative decay widths of vector quarkonia for the process of J/ψ(nS)→ηc(nS)γ and Υ(nS)→ηb(nS)γ (for principal quantum numbers n=1,2,3) in the framework of Bethe-Salpeter equation under the covariant instantaneous ansatz using a 4×4 form of ...
