A golden age for heavy-quarkonium physics dawned a decade ago, initiated by the
confluence of exciting advances in quantum chromodynamics (QCD) and an explosion of …

We investigate a new constraint on new-physics interpretations of the anomalies observed
in B→ D (*) τ ν decays making use of the lifetime of the B c-meson. A constraint is obtained …

Observations of exotic structures in the J/ψ p channel, which we refer to as charmonium-
pentaquark states, in Λ b 0→ J/ψ Kp decays are presented. The data sample corresponds to …

A bstract It has been shown recently that the anomalies observed in\(\overline {B}\to {D}^{\left
(*\right)}\tau {\overline {\nu}} _ {\tau}\) and\(\overline {B}\to\overline {K}{\ell}^{+}{\ell}^{-}\) …

CMS is a general purpose experiment, designed to study the physics of pp collisions at 14
TeV at the Large Hadron Collider (LHC). It currently involves more than 2000 physicists from …

During 2011 the LHCb experiment at CERN collected 1.0 fb− 1 of s=7~TeV pp collisions.
Due to the large heavy quark production cross-sections, these data provide unprecedented …

The production fraction of the B c-meson with respect to the sum of B-and B¯ 0 mesons is
measured in both 7 and 13 TeV center-of-mass (cm) energy pp collisions produced by the …

Using pp collision data corresponding to an integrated luminosity of 8.5 fb-1 recorded by the
LHCb experiment at center-of-mass energies of s= 7, 8, and 13 TeV, the observation of an …

We report the ground state masses of hadrons containing at least one charm and one
bottom quark using lattice quantum chromodynamics. These include mesons with spin (J) …

Semileptonic and nonleptonic decays of the B c meson to charmonium and D mesons are
studied in the framework of the relativistic quark model. The decay form factors are explicitly …
