“…A large mixing angle leads to similar contributions to both LFV decays which renders the τ channel non-competitive. Similar results are found in [35], where also a study using SU(5) without right-handed neutrinos is performed exhibiting larger differences between the τ → γ and µ → eγ branching fractions, although the predicted effects are smaller in general than for supersymmetric GUT seesaw models.…”

Abstract. This writeup of a talk at the 2011 Lepton-Photon symposium in Mumbai, India, summarises recent results in the charged-lepton flavour sector. I review searches for charged-lepton flavour violation, lepton electric dipole moments and flavour-conserving CP violation. I also discuss recent progress in τ -lepton physics and in the Standard Model prediction of the muon anomalous magnetic moment.

“…Selected reviews of these topics can be found in [7,23,[344][345][346], where many references can be found. The study of correlations between LFV, (g − 2) µ and EDMs in supersymmetric flavour models and SUSY GUTS can be found in [35,[347][348][349]. Analogous correlations in models with vector-like leptons have been presented in [350] and general expressions for these observables in terms of Wilson coefficients of dimension-six operators can be found in [351].…”

Towards the identification of new physics through quark flavour violating processes

We outline a systematic strategy which should help in this decade to identify New Physics (NP) beyond the Standard Model (SM) by means of quark flavour violating processes and thereby to extend the picture of short distance physics down to the scales as short as 10 −20 m and even shorter distance scales corresponding to energies of 100 TeV. Rather than using all possible flavour violating observables that will be measured in the coming years at the LHC, SuperKEKB and in Kaon physics dedicated experiments at CERN, J-PARC and Fermilab, we concentrate on those observables that are theoretically clean and very sensitive to NP. Assuming that the data on the selected observables by us will be very precise, we stress the importance of correlations between these observables as well as of future precise calculations of non-perturbative parameters by means of lattice QCD simulations with dynamical fermions. Our strategy consists of twelve steps which we will discuss in detail illustrating possible outcomes with the help of the SM, models with constrained Minimal Flavour Violation (CMFV), MFV at large and models with tree-level FCNCs mediated by neutral gauge bosons and scalars. We also briefly summarize the status of a number of concrete models. We propose DNA-charts that exhibit correlations between flavour observables in different NP scenarios. The models with new left-handed and/or right-handed currents and non-MFV interactions can be distinguished transparently in this manner. We emphasize the important role of the stringent CMFV relations between various observables as standard candles of flavour physics. The pattern of deviations from these relations may help in identifying the correct NP scenario. The success of this program will be very much facilitated through direct signals of NP at the LHC even if LHC will not be able to probe the physics at scales shorter than 4×10 −20 m. We also emphasize the importance of lepton flavour violation, electric dipole moments and (g − 2) e,µ in these studies.

Flavour and collider interplay for SUSY at LHC7

et al. 2012

The current 7 TeV run of the LHC experiment shall be able to probe gluino and squark masses up to values larger than 1 TeV. Assuming that hints for SUSY are found in the jets plus missing energy channel by the end of a 5 fb −1 run, we explore the flavour constraints on three models with a CMSSM-like spectrum: the CMSSM itself, a Seesaw extension of the CMSSM, and Flavoured CMSSM. In particular, we focus on decays that might have been measured by the time the run is concluded, such as B s → µµ and µ → eγ. We also analyse constraints imposed by neutral meson bounds and electric dipole moments. The interplay between collider and flavour experiments is explored through the use of three benchmark scenarios, finding the flavour feedback useful in order to determine the model parameters and to test the consistency of the different models.
