Searching for exotic B meson decays with the CMS L1 track trigger

TL;DR

This paper explores how the CMS phase II track trigger can detect exotic B-meson decays with displaced dimuon vertices, potentially surpassing current experiments in sensitivity.

Contribution

It demonstrates that the CMS L1 track trigger enables competitive searches for exotic B-meson decays involving displaced dimuons, with lower pT thresholds than existing triggers.

Findings

CMS can reach competitive sensitivity for exotic B decays

Lower pT thresholds improve detection of displaced dimuons

Potential to outperform LHCb and Belle II in certain searches

Abstract

The CMS phase II track trigger may allow for a displaced dimuon vertex trigger with qualitatively lower $p_T$ thresholds than existing dimuon triggers. With this technique, we show that the CMS reach for exotic $B$-meson decays involving a displaced dimuon resonance, such as a light, Higgs-mixed scalar, can be competitive with that of LHCb and Belle II.
