An inequality on the mass of the bottom quark [PDF]

open access: yesPhysics Letters B, 1978
Abstract We establish inequalities on the energy levels of two-particle systems interacting via the same potential with different masses and different angular momenta. When this is applied to the J ψ and ϒ particles, one gets an inequality on the mass difference between the heavy quark and the charmed quark as a function of the masses of the

Investigating bottom-quark Yukawa interaction at Higgs factory * [PDF]

open access: yesChinese Physics C, 2021
Abstract Measuring the fermion Yukawa coupling constants is important for understanding the origin of the fermion masses and their relationship with spontaneously electroweak symmetry breaking. In contrast, some new physics (NP) models change the Lorentz structure of the Yukawa interactions between standard model (SM) fermions and the SM-

Resolving charged hadrons in QED — gauge invariant interpolating operators

open access: yesJournal of High Energy Physics, 2022
Standard interpolating operators for charged mesons, e.g. J B = b ¯ $$ \overline{b} $$ iγ 5 u for B − , are not gauge invariant in QED and therefore problematic for perturbative methods.

Prospects for B s 0 $$ {B}_{(s)}^0 $$ → π 0 π 0 and B s 0 $$ {B}_{(s)}^0 $$ → ηη modes and corresponding CP asymmetries at Tera-Z

open access: yesJournal of High Energy Physics, 2022
The physics potential of measuring B s 0 $$ {B}_{(s)}^0 $$ → π 0 π 0 and B s 0 $$ {B}_{(s)}^0 $$ → ηη decays via four-photon final states at Tera-Z phase of CEPC or FCC-ee is investigated in this paper.

Searches for Scalar Top and Scalar Bottom Quarks at LEP2 [PDF]

open access: yes, 1997
Searches for scalar top and bottom quarks have been performed with data collected by the ALEPH detector at LEP. The data sample consists of 21.7 pb^-1 taken at sqrt{s} = 161, 170, and 172~GeV and 5.7 pb^-1 taken at sqrt{s} = 130 and 136~GeV.

Spectroscopy of mesons with bottom quarks [PDF]

open access: yesProceedings of 37th International Symposium on Lattice Field Theory — PoS(LATTICE2019), 2020
Preliminary results for the spectra of excited and exotic bottom mesons are presented. The calculation on a dynamical anisotropic ensemble exploits distillation, enabling the use of a large basis of interpolating operators including those proportional to the gluonic field strength which are relevant for hybrid states.

More on heavy tetraquarks in lattice QCD at almost physical pion mass

open access: yesEPJ Web of Conferences, 2018
We report on our progress in studying exotic, heavy tetraquark states, qq′ Q̅Q̅′. Using publicly available dynamical nf = 2 + 1 Wilson-Clover gauge configurations, generated by the PACS-CS collaboration, with pion masses ≃ 164, 299 and 415 MeV, we extend
