The light invisible boson in FCNC decays of B and $$B_c$$ B c mesons
European Physical Journal C: Particles and Fields, 2021 In this paper, we study the FCNC decay processes of B and $$B_c$$ B c meson, in which one invisible particle is emitted. Both the spin-0 and spin-1 cases are considered.

Meson properties at finite temperature in a three flavor nonlocal chiral quark model with Polyakov loop [PDF]
, 2010 We study the finite temperature behavior of light scalar and pseudoscalar meson properties in the context of a three-flavor nonlocal chiral quark model. The model includes mixing with active strangeness degrees of freedom, and takes care of the effect of

Leading isospin-breaking effects on the lattice [PDF]
, 2017 Isospin is an almost exact symmetry of strong interactions and the corrections to the isosymmetric limit are, in general, at the percent level. For several hadronic quantities, such as pseudoscalar meson masses or the kaon leptonic and semileptonic decay

The annihilation of virtual photons into pseudoscalar mesons [PDF]
The European Physical Journal C, 2001 We investigate the possibility to constrain the pion distribution amplitude from the gamma* gamma* -> pi transition. For a surprisingly large range in the two photon virtualities we find that the transition form factor is essentially independent of the distribution amplitude. This in turn entails a parameter-free prediction of QCD. The gamma* gamma*

The Okamoto-Nolen-Schiffer anomaly without rho-omega mixing
, 1996 We examine the effect of isospin-violating meson-nucleon coupling constants and of $\pi$-$\eta$ mixing on the binding-energy differences of mirror nuclei in a model that possesses no contribution from $\rho$-$\omega$ mixing.

Meson–baryon coupling constants of the SU(3) baryons with flavor SU(3) symmetry breaking
Physics Letters B, 2018 We investigate the strong coupling constants for the baryon octet–octet, decuplet–octet, and decuplet–decuplet vertices with pseudoscalar mesons within a general framework of the chiral quark-soliton model, taking into account the effects of flavor SU(3)

Decays of a NMSSM CP-odd Higgs in the low-mass region [PDF]
, 2017 A popular regime in the NMSSM parameter space involves a light CP-odd Higgs $A_1$. This scenario has consequences for e.g. light singlino Dark Matter annihilating in the $A_1$-funnel.

Strong decays of vector mesons to pseudoscalar mesons in the relativistic quark model
Physics Letters B, 2015 Strong decays of vector (S13) mesons to the pair of pseudoscalar (S01) mesons are considered in the framework of the microscopic decay mechanism and the relativistic quark model based on the quasipotential approach.
