ηc-nucleus bound states

open access: yesPhysics Letters B, 2020
ηc-nucleus bound state energies are calculated for various nuclei. Essential input for the calculations, namely the medium-modified D and D⁎ meson masses, as well as the density distributions in nuclei, are calculated within the quark-meson coupling (QMC)

Stark effect and dissociation of mesons in holographic conductor

open access: yesJournal of High Energy Physics, 2023
We study the meson spectrum of the N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory with N $$ \mathcal{N} $$ = 2 fundamental hypermultiplets for a finite electric field by using the D3/D7 model.

Superconformal baryon-meson symmetry and light-front holographic QCD [PDF]

open access: yes, 2015
We construct an effective QCD light-front Hamiltonian for both mesons and baryons in the chiral limit based on the generalized supercharges of a superconformal graded algebra.

Determination of the X(3872) meson quantum numbers. [PDF]

open access: yesPhysical Review Letters, 2013
The quantum numbers of the X(3872) meson are determined to be J(PC)=1(++) based on angular correlations in B(+)→X(3872)K(+) decays, where X(3872)→π(+)π(-)J/ψ and J/ψ→μ(+)μ(-).

Composite leptoquarks and anomalies in B-meson decays [PDF]

open access: yes, 2014
A bstractWe attempt to explain recent anomalies in semileptonic B decays at LHCb via a composite Higgs model, in which both the Higgs and an SU(2)L-triplet leptoquark arise as pseudo-Goldstone bosons of the strong dynamics.

Higher radial and orbital excitations in the charmed meson family [PDF]

open access: yes, 2015
Considering abundant experimental information of charmed mesons and the present research status, in this work we systematically study higher radial and orbital excitations in the charmed meson family by analyzing the mass spectrum and calculating their ...

Resolving the RpA and v2 puzzle of D0 mesons in p−Pb collisions at the LHC

open access: yesPhysics Letters B, 2023
It has been a challenge to understand the experimental data on both the nuclear modification factor and elliptic flow of D0 mesons in p−Pb collisions at LHC energies.

Free energies as invariants of Teichmüller like structures [PDF]

open access: yes, 2013
A Teichmüller like structure on the space of d-degree holomorphic maps on the circle S1, marked by conjugations to the map z 7→ z d, can be defined. Here we introduce a definition of free energy associated to this kind of dynamics as an invariant of ...

S-wave Meson-Nucleon Interactions and the Meson Mass in Nuclear Matter from Chiral Effective Lagrangians

open access: yes, 1995
Chiral effective lagrangians may differ in their prediction of meson-nucleon scattering amplitudes off-meson-mass-shell, but must yield identical S-matrix elements.
