Correlations between high-p_T and flavour physics

TL;DR

This paper explores the potential correlations between high transverse momentum processes and flavour physics, emphasizing how squark and gluino decay patterns relate to flavour-violating phenomena in B-mesons, and discusses the implications for future collider experiments.

Contribution

It highlights the connection between high-p_T physics and flavour violation, and discusses how future experiments can better constrain squark mixing parameters.

Findings

Current bounds still allow large flavour-violating squark decays.

Correlations between B-meson transitions and squark decays can be probed at future colliders.

Additional flavour data is necessary for proper interpretation of LHC results.

Abstract

Squark and gluino decays are governed by the same mixing matrices as the contributions to flavour violating loop transitions of B-mesons. This allows for possible direct correlations between flavour non-diagonal observables in B and high-p_T physics. The present bounds on squark mixing, induced by the low-energy data on b to s transitions, still allow for large contributions to flavour violating squark decays at tree level. Due to the restrictions in flavour tagging at the LHC, additional information from future flavour experiments will be necessary to interpret those LHC data properly. Also the measurement of correlations between various squark decay modes at a future ILC would provide information about the flavour violating parameters.
