Nonperturbative quark, gluon, and meson correlators of unquenched QCD [PDF]
, 2017 We present non-perturbative first-principle results for quark-, gluon- and meson $1$PI correlation functions of two-flavour Landau-gauge QCD in the vacuum. These correlation functions carry the full information about the theory.

Masses of doubly heavy-quark baryons in an extended chromomagnetic model [PDF]
, 2018 We extend the chromomagnetic model by further considering the effect of color interaction. The effective mass parameters between quark pairs ($m_{qq}$ or $m_{q\bar{q}}$) are introduced to account both the effective quark masses and the color interaction ...

Quark mass relations to four-loop order in perturbative QCD. [PDF]
Physical Review Letters, 2015 We present results for the relation between a heavy quark mass defined in the on-shell and minimal subtraction (MS[over ¯]) scheme to four-loop order. The method to compute the four-loop on-shell integral is briefly described and the new results are used

Probing new physics in class-I B-meson decays into heavy-light final states
Journal of High Energy Physics, 2021 With updated experimental data and improved theoretical calculations, several significant deviations are being observed between the Standard Model predictions and the experimental measurements of the branching ratios of B ¯ s 0 → D s ∗ + L ...

Quark Number Susceptibility with Finite Quark Mass in Holographic QCD
, 2011 We study the effect of a finite quark mass on the quark number susceptibility in the framework of holographic QCD. We work in a bottom-up model with a deformed AdS black hole and D3/D7 model to calculate the quark number susceptibility at finite ...

Quenched hadron spectroscopy with improved staggered quark action [PDF]
, 1997 We investigate light hadron spectroscopy with an improved quenched staggered quark action. We compare the results obtained with an improved gauge plus an improved quark action, an improved gauge plus standard quark action, and the standard gauge plus ...

Measurement of differential cross sections for top quark pair production using the lepton+jets final state in proton-proton collisions at 13 TeV [PDF]
, 2016 Differential and double-differential cross sections for the production of top quark pairs in proton-proton collisions at 13 TeV are measured as a function of jet multiplicity and of kinematic variables of the top quarks and the top quark-antiquark system.

CP asymmetry in the angular distribution of τ → KS πν τ decays
Journal of High Energy Physics, 2020 In this work, we study the C P asymmetry in the angular distribution of τ → K S πν τ decays, taking into account the known C P violation in K 0 − K ¯ 0 $$ {K}^0-{\overline{K}}^0 $$ mixing. It is pointed out for the first time that, once the well-measured

Light Quark Spin-Flavor Symmetry for Baryons Containing a Heavy Quark in Large N QCD
, 1993 The couplings and interactions of baryons containing a heavy quark are related by light quark spin-flavor symmetry in the large $N$ limit. The single pion coupling constant which determines all heavy quark baryon-pion couplings is equal to the pion ...
