New gauge boson Z' and lepton flavor violating decays and production of vector mesons | | Chong-Xing Yue

31 Jan 2016 | | Abstract: | Considering the constraints on the lepton flavor violating (LFV) couplings of
the new gauge boson $Z’$ to ordinary leptons from the experimental upper limit
for the LFV process $ell
ightarrow 3ell’$, we calculate the contributions of
$Z’$ to the LFV decays $V
ightarrowell_{i}ell_{j}$ with
$Vin{phi,J/Psi,Psi(2S),Upsilon^{(n)}}$ and $ au omu(e)phi$ in the
context of several $Z’$ models. We find that all $Z’$ models considered in this
paper can produce significant contributions to these decay processes and make
the value of branching ratio $Br( au o ephi)$ above its experimental upper
limit. The experimental upper limit of $ au o ephi$ can give more severe
constraints on these $Z’$ models than those given by $ au o3e$. | | Source: | arXiv, 1602.0211 | | Services: | Forum | Review | PDF | Favorites | |
