Spectroscopy of SU(4) composite Higgs theory with two distinct fermion representations

We have simulated the SU(4) lattice gauge theory coupled to dynamical fermions in the fundamental and two-index antisymmetric (sextet) representations simultaneously. Such theories arise naturally in…

|Vub | from B →π ν decays and (2+1)-flavor lattice QCD

We present a lattice-QCD calculation of the B → πlν semileptonic form factors and a new determination of the CKM matrix element |Vub|. We use the MILC asqtad (2+1)-flavor lattice configurations at…

Charmed and light pseudoscalar meson decay constants from four-flavor lattice QCD with physical light quarks

We compute the leptonic decay constants f D + , f D s , and f K + and the quark-mass ratios m c / m s and m s / m l in unquenched lattice QCD using the experimentally determined value of f π + for…

Lattice study of conformal behavior in SU(3) Yang-Mills theories

Using lattice simulations, we study the extent of the conformal window for an SU(3) gauge theory with N{sub f} Dirac fermions in the fundamental representation. We extend our recently reported work,…

B - and D -meson leptonic decay constants from four-flavor lattice QCD

We calculate the leptonic decay constants of heavy-light pseudoscalar mesons with charm and bottom quarks in lattice quantum chromodynamics on four-flavor QCD gauge-field configurations with…

$B$- and $D$-meson decay constants from three-flavor lattice QCD

We calculate the leptonic decay constants ofB (s) andD (s) mesons in lattice QCD using staggered light quarks and Fermilab bottom and charm quarks. We compute the heavy-light meson correlation…

Lattice study of the conformal window in QCD-like theories.

The extent of the conformal window for an SU(3) gauge theory with N{f} Dirac fermions in the fundamental representation is studied to present lattice evidence that the infrared behavior is governed by a fixed point.

Infrared Monitoring of the Microquasar GRS 1915+105: Detection of Orbital and Superhump Signatures

We present the results of 7 years of K-band monitoring of the low-mass X-ray binary GRS 1915+105. Positive correlations between the infrared flux and the X-ray flux and X-ray hardness are…

Strongly interacting dynamics and the search for new physics at the LHC

We present results for the spectrum of a strongly interacting SU(3) gauge theory with Nf = 8 light fermions in the fundamental representation. Carrying out nonperturbative lattice calculations at the…
