Improving the theoretical prediction for the $B_s-\bar{B}_s$ width difference: matrix elements of next-to-leading order $\Delta B=2$ operators [PDF]
, 2017 We present lattice QCD results for the matrix elements of $R_2$ and other dimension-7, $\Delta B = 2$ operators relevant for calculations of $\Delta \Gamma_s$, the $B_s-\bar{B}_s$ width difference. We have computed correlation functions using 5 ensembles

Large methane oxidation across an oxygen gradient in Baltic Sea deep waters
Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.Abstract Robust estimations of methane (CH4) oxidation in marginal seas remain elusive, making CH4 budgets particularly uncertain. Here, we investigate the CH4 benthic source and bottom layer oxidation across the entire Baltic Sea using concentration and stable isotope (δ13C‐CH4) profiles along oxygen and salinity gradients.

Search for the standard model Higgs boson produced in association with a W or a Z boson and decaying to bottom quarks [PDF]
, 2013 A search for the standard model Higgs boson (H) decaying to bb when produced in association with a weak vector boson (V) is reported for the following channels: W(μν)H, W(eν)H, W(τν)H, Z(μμ)H, Z(ee)H, and Z(νν)H.

Final-state rescattering mechanism in bottom-baryon decays
Journal of High Energy PhysicsThe first observation of CP violation in baryon decays was recently reported by the LHCb collaboration in Λ b 0 $$ {\Lambda}_b^0 $$ → pK − π + π − with A CP = (2.45 ± 0.46 ± 0.10)%, which inspires the study on baryon non-leptonic decays. In this work, we

Journal of High Energy Physics, 2017 We provide a systematic renormalization group formalism for the mass effects in the relation of the pole mass m Q pole and short-distance masses such as the M S ¯ $$ \overline{\mathrm{MS}} $$ mass m ¯ Q $$ {\overline{m}}_Q $$ of a heavy quark Q, coming ...

Annalen der Physik, Volume 537, Issue 12, December 2025.A set of particle representations, familiar from the Standard Model, collectively form a superalgebra. Those representations mirroring the behaviour of the Standard Model's gauge bosons, and three generations of fermions, are each included in this algebra, with exception only to those representations involving the top quark.

BB interactions with static bottom quarks from Lattice QCD [PDF]
, 2015 The isospin, spin and parity dependent potential of a pair of B mesons is computed using Wilson twisted mass lattice QCD with two flavours of degenerate dynamical quarks. The B meson is addressed in the static-light approximation, i.e.

Probing Quark Gluon Plasma by Heavy Flavors [PDF]
, 2011 The drag and diffusion coefficients of charm and bottom quarks propagating through quark gluon plasma (QGP) have been evaluated within the framework of perturbative Quantum Chromodynamics (pQCD).

Momentum dependence of drag coefficients and heavy flavour suppression in quark gluon plasma
, 2011 The momentum dependence of the drag coefficient of heavy quarks propagating through quark gluon plasma (QGP) has been evaluated. The results have been used to estimate the nuclear suppression factor of charm and bottom quarks in QGP.

New Topflavor Models with Seesaw Mechanism [PDF]
, 2000 New class of models are constructed in which the third family quarks, but not leptons, experience a new SU(2) or U(1) gauge force. Anomaly cancellation enforces the introduction of spectator quarks so that the top and bottom masses are naturally ...
