Probing lepton flavor violating decays in MSSM with non-holomorphic soft terms

“…Thus, approximately a region with |A eµ | above 60 GeV is eliminated. The above only demonstrate the stringency of the constraints on the first two generations of the off-diagonal Yukawa couplings arising from the null observation of µ → eγ [130] along with the CMS results on the first two generations [132,162]. Figure 9b is not so different from figure 5b indicating only an insignifant influence.…”

Generalized 2HDM with wrong-sign lepton-Yukawa coupling, in light of $$g_{\mu }-2$$ and lepton flavor violation at the future LHC

“…For validation, we have generated the backgrounds for √ s = 13 TeV using Madgraph@NLO[111] and compared with the background event expectation as given in the CMS paper[110]. We have found that the backgrounds are consistent with the CMS background numbers up to 97% .…”

“…Therefore the final state of our interest is + − + / E T . The SM backgrounds that give rise to similar final states consist of τ τ/ee/μμ, t t, W ± +jets, di-boson, SM Higgs [35,110]. The major and irreducible background turns out to be the leptonic final state of τ τ .…”

CP Violation for the Heavens and the Earth

“…the recent search bounds by CMS [53] turns out to be more stringent on the product ρ tt ρ τµ than from the recent Belle measurement of τ → µγ [54]. This means that a hint could well appear with full Run 2 data, as CMS only used 36 fb −1 data at 13 TeV in Ref.…”
