Phenomenology of LFV at low-energies and at the LHC: strategies to probe the SUSY seesaw

A. M. Teixeira, A. Abada, A. J. R. Figueiredo +1

We study the impact of a type-I SUSY seesaw concerning lepton flavour violation (LFV) at low-energies and at the LHC. At the LHC, $ χ_2^0\to \tilde \ell \,\ell \to \ell \,\ell\,χ_1…

E. A. Kuraev, Yu. M. Bystritskiy, V. V. Bytev +2

The s-channel annihilation of proton and antiproton into a neutral pion and a real or virtual photon followed by lepton pair emission is studied. Such mechanism is expected to play…

Beyond the MSSM Higgs with d=6 effective operators

I. Antoniadis, E. Dudas, D. M. Ghilencea +1

We continue a previous study of the MSSM Higgs Lagrangian extended by all effective operators of dimension d=6 that can be present beyond the MSSM, consistent with its symmetries.…

Specific Dark Matter signatures from hidden U(1)

Yann Mambrini

Several constructions motivate the existence of a dark $U (1)_{D}$ gauge boson which interacts with the Standard Model only through its kinetic mixing or loop induced processes. We de…

Determining the photon polarization of the b --> s gamma using the B --> K1(1270) gamma --> (K pi pi) gamma decay

Emi Kou, Alain Le Yaouanc, Andrey Tayduganov

Recently the radiative B decay to the strange axial-vector mesons, B --> K1(1270) gamma, has been observed with rather large branching ratio. This process is particularly interesti…
