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 ...

Elastic production of Vector Mesons at HERA: study of the scale of the interaction and measurement of the helicity amplitudes [PDF]

, 1999
A compilation of H1 and ZEUS cross section measurements for elastic vector meson production is presented as a function of the scale $K^2 = (Q^2+M_V^2)/4$, where Q^2 is the exchanged photon virtuality and M_V is the mass of the vector meson.

Exclusive c → uγ transitions of Bc meson [PDF]

EPJ Web of Conferences
We study the rare decays of the Bc meson induced by the flavour changing neutral current c → uγ transition. In the Standard Model they are strongly suppressed by the Glashow-Iliopoulos-Maiani mechanism, therefore they are sensitive to new physics.

Testing the dynamics of high energy scattering using vector meson production

, 2004
I review work on diffractive vector meson production in photon-proton collisions at high energy and large momentum transfer, accompanied by proton dissociation and a large rapidity gap. This process provides a test of the high energy scattering dynamics,

Mass Spectrum of Noncharmed and Charmed Meson States in Extended Linear-Sigma Model

Particles
The mass spectrum of different meson particles is generated using an effective Lagrangian of the extended linear-sigma model (eLSM) for scalar and pseudoscalar meson fields and quark flavors, up, down, strange, and charm.

Exclusive heavy vector meson production at next-to-leading order in the dipole picture

Physics Letters B, 2021
We calculate exclusive production of a longitudinally polarized heavy vector meson at next-to-leading order in the dipole picture. The large quark mass allows us to separately include both the first QCD correction proportional to the coupling constant αs,

Light Vector Meson Spectroscopy [PDF]

, 2001
The current situation for vector meson spectroscopy is outlined, and it is shown that the data are inconsistent with the generally-accepted model for meson decay. A possible resolution in terms of exotic (hybrid) mesons is given. Although this hypothesis
