Physics Letters B, 2022 We carry out the first lattice QCD derivation of the mixing energy and the mixing angle of the pseudoscalar charmonium and glueball on two gauge ensembles with Nf=2 degenerate dynamical charm quarks. The mixing energy is determined to be 49(6) MeV on the

Annihilation Diagrams in Two-Body Nonleptonic Decays of Charmed Mesons
, 1993 In the pole-dominance model for the two-body nonleptonic decays of charmed mesons $D \rightarrow PV$ and $D \rightarrow VV$, it is shown that the contributions of the intermediate pseudoscalar and the axial-vector meson poles cancel each other in the ...

Chiral Symmetry restoration from the hadronic regime
EPJ Web of Conferences, 2017 We discuss recent advances on QCD chiral symmetry restoration at finite temperature, within the theoretical framework of Effective Theories. U(3) Ward Identities are derived between pseudoscalar susceptibilities and quark condensates, allowing to explain

Strong decays of excited vector mesons [PDF]
arXiv, 2017 We study two nonets of excited vector mesons, predominantly corresponding to radially excited vector mesons with quantum numbers $n\hspace{0.08cm} ^{2S+1}L_{J}$ $=2^3S_1$ and to orbitally excited vector mesons with quantum numbers $n\hspace{0.08cm} ^{2S+1}L_{J}=1^3D_1$.

Next-to-leading order corrections to deeply virtual production of pseudoscalar mesons
Physics Letters B, 2017 We complete the perturbative next-to-leading order corrections to the hard scattering amplitudes of deeply virtual meson leptoproduction processes at leading twist-two level by presenting the results for the production of flavor singlet pseudoscalar ...
