A Relativistic Model for Heavy Mesons
<p>Motivated by the present interest in the heavy quark effective theory, we construct a model for heavy mesons based on a relativistic bound state wave equation, the Gross equation. The kernel we use is based on scalar confining and vector Coulomb potentials. Wave functions are treated to leading …

Photoproduction of ηc mesons in ultra-peripheral Pb+Pb collisions at √sNN= 5.02 TeV at the LHC
… to examine the exclusive photoproduction of heavy mesons. The Pb+Pb collisions generated at CERN's Large Hadron Collider at √sNN = 5:02 TeV provide new data which has been predicted to have a reconstructable signal for the ηc meson. Analysis of ALICE's Run 2 Pb+Pb collision data for evidence …

Effective Field Theory for Doubly Heavy Baryons and Lattice QCD
… we study effective field theories for doubly heavy baryons and lattice QCD. We construct a chiral Lagrangian for doubly heavy baryons and heavy mesons that is invariant under heavy quark-diquark symmetry at leading order and includes the leading O(1/m_Q ) symmetry violating operators. The …
