Description
B decays into multiple muons are predictions of well motivated BSM theories shuch as Composite Higgs models. In this talk, I will present the results of the phenomenologycal analysis developed in order to probe the sensitivity of the LHCb detector to those decay chains, showing that the proposed search could probe extensive regions of the parameter space which could explain the commented anomalies. By exploiting the use of tracks only reconstructed in subsystems of the detector at the high-level LHCb trigger, B(B0
s → a1a2) < 10−8 and B(B+ → K+a1a2) < 10−9 could be reached in the muon channel across seven orders of magnitude in the lifetime of the Goldstone bosons. Additionally, the reach of the proposed CODEX-b experiment is studied as well in the long-lived scenario, whilst the heaviest scalar is always considered a prompt resonance.
