TL;DR

This paper explores weak decays of heavy hadrons involving light quarks, highlighting their potential for experimental observation and their usefulness as a QCD laboratory to study light quark behavior in a heavy quark background.

Contribution

It provides an analysis of light-quark decays in heavy hadrons, emphasizing their phase-space suppression and potential for experimental study as a QCD laboratory.

Findings

Decays are phase-space suppressed but potentially observable.

These decays serve as a laboratory for studying light quark behavior.

Potential for experimental access in the near future.

Abstract

We consider weak decays of heavy hadrons (bottom and charmed) where the heavy quark acts as a spectator. Theses decays are heavily phase-space suppressed but may become experimentally accessible in the near future. These decays are interesting as a QCD laboratory to study the behaviour of the light quarks in the colour-background field of the heavy spectator.
