Dissipative effects in semileptonic B decays

TL;DR

This paper investigates how dissipative effects influence the evolution and decay of neutral B-mesons using quantum dynamical semigroups, introducing new parameters that could be experimentally observed.

Contribution

It introduces a novel framework incorporating dissipative effects into B-meson decay analysis via quantum dynamical semigroups, with six measurable phenomenological constants.

Findings

New nonstandard terms in observables due to dissipation

Potential detection of dissipation parameters in future experiments

Enhanced understanding of B-meson decay dynamics

Abstract

We study the time evolution and decay of the neutral B-meson system using quantum dynamical semigroups. New, nonstandard terms appear in the expression of relevant observables; they can be parametrized in terms of six phenomenological constants. Although very small, these parameters may be detected in the new generation of dedicated B-meson experiments.
