Search for charged lepton flavor violation of vector mesons in the U(1)_XSSM
arxiv(2024)
摘要
Charged lepton flavor violation (CLFV) represents a clear new physics (NP)
signal beyond the standard model (SM). In this work, we investigate the CLFV
decays of vector mesons V→ l_i^±l_j^∓ with V∈{ϕ,
J/Ψ, Υ(1S), Υ(2S),Υ(3S)} in the U(1)_XSSM. Considering the SM-like Higgs boson mass within 3σ
region, we discuss the corresponding constraints on the relevant parameter
space of the model, which indicate this model can produce significant
contributions to such CLFV decays. From the numerical analyses, the main
sensitive parameters and CLFV sources originate from the non-diagonal elements
correspond to the initial and final generations of the leptons. And the
branching ratios to these CLFV processes can easily reach the present
experimental upper bounds. Therefore, searching for CLFV processes of vector
mesons may be an effective channel to study new physics.
