Semileptonic form factor ratio B_s->D_s/B->D and its application to BR(B^0_s->Î¼^+Î¼^-)

Daping Du, Carleton DeTar, Andreas Kronfeld +3

We present a (2+1)-flavor lattice QCD calculation of the form factor ratio between the semileptonic decays $B ˉ_{s}^{0} \to D_{s}^{+} l^{-} I^ˉ ½$ and $B ˉ^{0} \to D^{+} l^{-} I^ˉ ½$ . This…

Finite Temperature Lattice QCD with Clover Fermions

Claude Bernard, Tom Blum, Thomas A. DeGrand +9

We report on our simulation of finite temperature lattice QCD with two flavors of $O (a)$ Symanzik-improved fermions and $O (a^{2})$ Symanzik-improved glue. Our thermodyn…

Form factors for semileptonic B-decays with HISQ light quarks and clover b-quarks in Fermilab interpretation

Hwancheol Jeong, Carleton DeTar, Aida El-Khadra +7

We compute the vector, scalar, and tensor form factors for the $B \to I ¨ $ , $B \to K$ , and $B_{s} \to K$ amplitudes, which are needed to describe semileptonic $B$ -meson decay rates for b…

$B \to D^{(*)}$ decays from $N_{f} = 2 + 1 + 1$ highly improved staggered quarks and clover $b$ -quark in the Fermilab interpretation

Pietro Butti, Carleton DeTar, Aida El-Khadra +9

We present an update on the analysis of semileptonic $B \to D^{(*)}$ decays at non-zero recoil. Our computation employs $2 + 1 + 1$ FNAL-MILC ensembles with highly improved…

Lattice Field Theory Study of Magnetic Catalysis in Graphene

Carleton DeTar, Christopher Winterowd, Savvas Zafeiropoulos

We discuss the simulation of the low-energy effective field theory (EFT) for graphene in the presence of an external magnetic field. Our fully nonperturbative calculation uses meth…

Baryon Density Correlations in High Temperature Hadronic Matter

Claude Bernard, Thomas A. DeGrand, Carleton DeTar +4

As part of an ongoing effort to characterize the high temperature phase of QCD, in a numerical simulation using the staggered fermion scheme, we measure the quark baryon density in…
