Title: CP violation in h→ττ and LFV h→μτ

Abstract

The CMS Collaboration has reported a possible lepton flavor violating (LFV) signal . Whereas this does not happen in the standard model (SM), we point out that new physics responsible for this type of decay would, in general, also produce charge-parity (CP) violation in . We estimate the size of this effect in a model independent manner and find that a large asymmetry, of order 25%, is allowed by current constraints.

Leptonic CP violation in Z sup 0 decays

Journal Article Choudhury, D ; Joshipura, A S ; Rindani, S D - Physical Review Letters; (United States)

An SU(2){sub {ital L}}{direct product}U(1){sub {ital Y}} model containing exotic charged leptons can allow sizeable leptonic flavor violations (LFV) and hence rare {ital Z} decays into leptons of different flavors. The rates as well as {ital CP}-violating asymmetries are constrained using available limits on LFV and data from the CERN {ital e}{sup +}{ital e{minus}} collider LEP on {ital Z}{r arrow}{ital l}{sub {ital i}l{ital i}},{ital l}{sub {ital i}}={ital e},{mu},{tau}. Sizeable {ital CP}-violating rate asymmetries are theoretically possible in the model and are allowed by the former data. In contrast, the measured leptonic {ital Z} widths severely constrain these asymmetries. As amore »« less

CP violating lepton asymmetry from B decays in supersymmetric grand unified theories

Journal Article Dutta, Bhaskar ; Mimura, Yukihiro ; Santoso, Yudi - Physical Review. D, Particles Fields

We investigate the effect of the dimuon CP asymmetry from the B decay modes, recently observed at 3.2{sigma} deviation from the standard model (SM) by the D0 Collaboration, in the context of SU(5) and SO(10) grand unified theory models. We exhibit that a large amount of flavor violation between the second and the third generation is generated due to the large neutrino atmospheric mixing angle and this flavor violation can be responsible for the large CP asymmetry, i.e., a{sub sl}{sup s}=(-12.7{+-}5.0)x10{sup -3} (assuming 2{sigma} error in the prediction of the standard model value of {Gamma}{sub 12}{sup s}/M{sub 12}{sup s} andmore »« less

Measurements of Branching Fraction and CP Violation inB Meson Rare Decays to Final States containing eta or eta' Mesons in the BaBar Experiment at SLAC

Thesis/Dissertation Lazzaro, Alfio

Note that the main goal of this thesis work is the measurement of the branching fractions, charge asymmetry, and Time-Dependent CP Violation in η'K⁰ mode. All other measurements are reported here for completion because they are connected by similar physics arguments. They are part of the Milan analysis activity, done by undergraduate students. They should not be considered as done in this thesis work. The measurements of the two body-modes ηη, ηΦ, and η'Φare used to determine a theoretical bound based on SU(3) flavor symmetry for the difference between SM prediction and the experimental measurements of CP violation parameters inmore »« less

CP violation and scalar lepton flavor oscillation

Journal Article Bowser-Chao, D ; Keung, W - Physical Review, D

Lepton flavor violation can be induced in supersymmetry by the mixing of two or more of the leptonic scalar partners, {tilde l}{r_arrow}{tilde l}{sup {prime}}, where {tilde l},{tilde l}{sup {prime}}={tilde e},{tilde {mu}},{tilde {tau}}. Krashnikov and Arkani-Hamed {ital et al.} pointed out that this effect may be observable at the Next Linear Collider, through slepton pair production with subsequent lepton-flavor-violating (LFV) decays. If the slepton mixing involves all three generations, CP violation from the Cabibbo-Kobayashi-Maskawa phase could lead to asymmetries between the observed LFV decays {tilde l}{r_arrow}{tilde l}{sup {prime}} and {bar {tilde l}}{r_arrow}{bar {tilde l}}{sup {prime}}. We lay down the formalism andmore »« less

Looking forward to lepton-flavor-violating ALPs

Journal Article Calibbi, Lorenzo ; Redigolo, Diego ; Ziegler, Robert ; ... - Journal of High Energy Physics (Online)

We assess the status of past and future experiments on lepton flavor violating (LFV) muon and tau decays into a light, invisible, axion-like particle (ALP), a. We propose a new experimental setup for MEG II, the MEGII-fwd, with a forward calorimeter placed downstream from the muon stopping target. Searching for μ → ea decays MEGII-fwd is maximally sensitive to LFV ALPs, if these have nonzero couplings to right-handed leptons. The experimental set-up suppresses the (left-handed) Standard Model background in the forward direction by controlling the polarization purity of the muon beam. The reach of MEGII-fwd is compared with the presentmore »« less
