ETM Collaboration: Karl Jansen, Chris Michael, Andrea Shindler, Marc, Wagner
TL;DR
This study uses twisted mass lattice QCD to compute static-light meson masses, extrapolating results to predict B and B_s meson spectra across various light quark masses.
Contribution
First lattice QCD calculation of static-light meson spectrum with Wilson twisted mass, providing predictions for B and B_s mesons at different light quark masses.
Findings
Computed meson masses for five light quark masses
Extrapolated results to physical B and B_s meson spectra
Provided insights into meson mass dependence on light quark mass
Abstract
We compute the static-light meson spectrum using two-flavor Wilson twisted mass lattice QCD. We have considered five different values for the light quark mass corresponding to 300 MeV < m_PS < 600 MeV. We have extrapolated our results, to make predictions regarding the spectrum of B and B_s mesons.
