Quark-hadron duality at work: lifetimes of bottom baryons

Journal of High Energy Physics, 2023
In the 1990s, very low experimental values for the lifetime ratio τ(Λ b )/τ(B d ) triggered a considerable amount of doubt in the applicability of the heavy quark expansion (HQE), which is based on the assumption of quark-hadron duality (QHD) for ...

Disintegration of beauty: a precision study

Journal of High Energy Physics, 2023
We update the Standard Model (SM) predictions for B-meson lifetimes within the heavy quark expansion (HQE). Including for the first time the contribution of the Darwin operator, SU(3) F breaking corrections to the matrix element of dimension-six four ...

The mass spectrum and wave functions of the B c system

Journal of High Energy Physics, 2022
The spectrum and relativistic wave functions of B c system are investigated via solving the complete Salpeter equation. Emphases are put on the study of the partial waves of each J P state.

Non-factorisable effects in the decays B ¯ s 0 → D s + π − $$ {\overline{B}}_s^0\to {D}_s^{+}{\pi}^{-} $$ and B ¯ 0 → D + K − $$ {\overline{B}}^0\to {D}^{+}{K}^{-} $$ from LCSR

Journal of High Energy Physics, 2023
In light of the current discrepancies between the recent predictions based on QCD factorisation (QCDF) and the experimental data for several non-leptonic colour-allowed two-body B-meson decays, we obtain new determinations of the non-factorisable soft ...

Jet Quenching in Non-Conformal Holography

, 2011
We use our non-conformal holographic bottom-up model for QCD described in 1012.0116 to further study the effect of the QCD trace anomaly on the energy loss of both light and heavy quarks in a strongly coupled plasma.

Construction of bbu¯d¯ tetraquark states on lattice with NRQCD bottom and HISQ up and down quarks [PDF]

, 2020
We construct $bb\bar{u}\bar{d}$ states on lattice using NRQCD action for bottom and HISQ action for the light up/down quarks. The NRQCD-HISQ tetraquark operators are constructed for "bound" $[bb][\bar{u}\bar{d}]$ and "molecular" $[b\bar{u}] [b\bar{d ...

Standard Model predictions for lepton flavour universality ratios of inclusive semileptonic B decays

Journal of High Energy Physics, 2022
We present Standard Model predictions for lepton flavour universality ratios of inclusive B → X(c) ℓ ν ¯ ℓ $$ \ell {\overline{\nu}}_{\ell } $$ . For the ℓ = μ, e, these ratios are very close to unity as expected.

Search for Resonances Decaying to Top and Bottom Quarks with the CDF Experiment. [PDF]

Physical Review Letters, 2015
We report on a search for charged massive resonances decaying to top (t) and bottom (b) quarks in the full data set of proton-antiproton collisions at a center-of-mass energy of √[s]=1.96  TeV collected by the CDF II detector at the Tevatron ...

Top and bottom quark condensates

Zeitschrift f�r Physik C Particles and Fields, 1991
It is possible that electroweak symmetry might be broken dynamically by a condensate of top quarks. We extend a previous study of top quark dynamics to include the bottom quark. The simultaneous gap equations in dressed ladder approximation for∑ t (p),∑ b (p) are studied numerically ...

Deciphering Universal Extra Dimension from the top quark signals at the CERN LHC [PDF]

, 2010
Models based on Universal Extra Dimensions predict Kaluza-Klein (KK) excitations of all Standard Model (SM) particles. We examine the pair production of KK excitations of top- and bottom-quarks at the Large Hadron Collider.
