Resonance dynamics in the coherent η meson production in the (p,p′) reaction on the spin–isospin saturated nucleus

Physics Letters B, 2014
For the forward going proton and η meson, the coherent η meson production in the (p,p′) reaction on the spin–isospin saturated nucleus occurs only due to the η meson exchange interaction between the beam proton and nucleus.

Probing kaon meson condensations through gravitational waves during neutron star inspiral phases

Physics Letters B
Gravitational waves from binary neutron star merger events have shown unparalleled advantages in deciphering the stellar internal structure, yet it remains underexplored to seek clues about kaon meson condensations inside massive neutron stars through ...

Revealing transversity GPDs through the photoproduction of a photon and a ρ meson

EPJ Web of Conferences, 2016
Photoproduction of a pair of particles with large invariant mass is a natural extension of collinear QCD factorization theorems which have been much studied for deeply virtual Compton scattering and deeply virtual meson production.

Light meson mass spectra and pion electromagnetic form factor as a bound system in 3 + 1 dimensional QCD

Results in Physics, 2018
We investigate the Bethe-Salpeter-like amplitude in 3 + 1 dimensions. This involves a system comprising a quark and antiquark combined by gauge fields to satisfy gauge invariance. We derive the equation of motion for this system and construct a series of

Decaimiento no leptónico del mesón Bc considerando mesones excitados radialmente en el estado final

Iteckne, 2013
En el presente trabajo se muestra parte del estudio del decaimiento no leptónico del mesón Bc, considerado un mesón pseudoescalar o vectorial excitado radialmente (n = 2) en el estado final, se asume la hipótesis de factorización y utiliza el modelo de ...

In-medium Properties of Hadrons

EPJ Web of Conferences, 2012
An overview is given over recent results on in-medium properties of hadrons, obtained in experiments with photon, proton and deuteron beams at ANKE, CBELSA/TAPS, Crystal Ball, HADES, and BigRIPS.

Rapidity resummation for B-meson wave functions

EPJ Web of Conferences, 2014
Transverse-momentum dependent (TMD) hadronic wave functions develop light-cone divergences under QCD corrections, which are commonly regularized by the rapidity ζ of gauge vector defining the non-light-like Wilson lines.

Charmed meson production at LHCb

EPJ Web of Conferences, 2016
Measurements of charm meson production are important tests for QCD predictions and LHCb is uniquely suited to perform these measurements in the forward region.

Scrutinizing Dark-Matter Scenarios with B → (K,$K^{\ast }$)$\overline{\mathit{\nu }}$ν Decays

Universe
Conceivable explanations of Belle-II measurements of a (surprising) excess of missing energy decays of the B meson to the K meson not covered by standard model neutrino–antineutrino pairs might be offered by additional contributions of dark matter ...
