Coulomb artifacts and breakdown of perturbative matching in lattice NRQCD

Journal of High Energy Physics, 2017
By studying an explicit analytical solution of the Schrödinger equation with the Coulomb potential on the lattice we demonstrate a breakdown of perturbative matching for the description of the Coulomb artifacts in lattice NRQCD, which leads to a large ...

Jets and the physics of new heavy quarks

Nuclear Physics B, 1983
Abstract We have developed methods that can be used to isolate a clean sample of events with pair-produced heavy quarks in e + e − collisions. We show that most of the fundamental properties of a given heavy quark, as they would appear in pair production or in weak decays, can be deduced from a careful examination of this purified sample.

Long distance effects in inclusive rare B decays and phenomenology of B ¯ $$ \overline{B} $$ → X d ℓ+ℓ −

Journal of High Energy Physics, 2019
Rare inclusive B decays such as B ¯ $$ \overline{B} $$ → X s(d) ℓ + ℓ − are interesting probes for physics beyond the Standard Model. Due to the complementarity to their exclusive counter- parts, they might shed light on the anomalies currently seen in ...

Power-enhanced leading-logarithmic QED corrections to B q → μ + μ −

Journal of High Energy Physics, 2019
We provide a systematic treatment of the previously discovered power- enhanced QED corrections to the leptonic decay B q → μ + μ − (q = d, s) in the frame- work of soft-collinear effective theory (SCET).

How to employ B ¯ d 0 → J / ψ π η , K ¯ K $$ {\overline{B}}_d^0\to J/\psi \left(\uppi \eta, \overline{K}K\right) $$ decays to extract information on πη scattering

Journal of High Energy Physics, 2017
We demonstrate that dispersion theory allows one to deduce crucial information on πη scattering from the final-state interactions of the light mesons visible in the spectral distributions of the decays B ¯ d 0 → J / ψ π 0 η , K + K − , K 0 K ¯ 0 ...

CP violation in multibody B decays from QCD factorization

Journal of High Energy Physics, 2017
We test a data-driven approach based on QCD factorization for charmless three-body B-decays by confronting it to measurements of CP violation in B − → π − π + π −.
