Heavy quark correlators in an instanton liquid model with perturbative corrections [PDF]
, 2020 In the present work we consider the influence on the heavy quark correlators due to the instanton background in the framework of instanton liquid model (ILM) of QCD vacuum by taking into account also the perturbative gluon effects.

Status of heavy quark physics on the lattice [PDF]
Nuclear Physics B - Proceedings Supplements, 1999 The status of lattice calculations of some phenomenology of heavy quarks is presented. Emphasis is on progress made in calculating those quantities relevant to estimating parameters of the quark mixing matrix, namely leptonic decay constants, the bag parameter of neutral $B$ mixing, and semileptonic form factors.

RECENT PROGRESS IN HEAVY QUARK PHYSICS [PDF]
Lepton-Photon 01, 2002 Some of the recent progress in heavy quark physics is reviewed. Special attention is paid to inclusive methods for determining Vub and factorization in nonleptonic [Formula: see text] decays. Theoretical predictions for [Formula: see text] production near threshold are also discussed.

Sizable time-reversal violating effects in bottom baryon decays
Journal of High Energy Physics, 2022 We study time-reversal (T) asymmetries in the charmless two-body decays of antitriplet bottom baryons. We find that in B b → B n P with B b = ( Ξ b − $$ {\Xi}_b^{-} $$ , Ξ b 0 $$ {\Xi}_b^0 $$ , Λ b ) and B n (P) a octet baryon (pseudoscalar meson), the ...

Measurement of the Top Quark Mass in the Dilepton Final State using the Matrix Element Method [PDF]
, 2008 The top quark, discovered in 1995 by the CDF and D0 experiments at the Fermilab Tevatron Collider, is the heaviest known fundamental particle. The precise knowledge of its mass yields important constraints on the mass of the yet-unobserved Higgs boson ...

Prediction of the CP asymmetry C 00 in B0→D0D0¯ $$ {B}^0\to {D}^0\overline{D^0} $$ decay
Journal of High Energy Physics, 2017 Of all B→DD¯ $$ B\to D\overline{D} $$ decays, the B0→D0D0¯ $$ {B}^0\to {D}^0\overline{D^0} $$ decay has the smallest observed branching ratio as it takes place primarily via the suppressed W-exchange diagram.

Heavy quark physics on the lattice with improved nonrelativistic actions
, 2010 Hadrons containing heavy quarks, in particular b quarks, play an important role in high energy physics. Measurements of their electroweak interactions are used to test the Standard Model and search for new physics.

Topics in Theoretical Particle Physics and Cosmology [PDF]
, 2007 We first delve into particle phenomenology with a study of soft-collinear effective theory (SCET), an effective theory for Quantum Chromodynamics for when all particles are approximately on their light-cones. In particular, we study the matching of SCET(
