Sleptonic SUSY: from UV framework to IR phenomenology

We study an attractive scenario, "Sleptonic SUSY", which reconciles the 125 GeV Higgs scalar and the non-observation of superpartners thus far with potentially pivotal roles for slepton phenomenology: providing viable ongoing targets for LHC discovery, inc ...

Probing top-antitop resonances with tt scattering at LHC14

Rakhi Nandalal Mahbubani, Da Liu

We explore the sensitivity of the LHC at 14 TeV centre -of -mass energy (LHC14) to the single production and decay of top-antitop resonances in the four -top final state. We focus on the same -sign dilepton channel, and work within a simplified model with ...

We report a study of the suppressed B- -> DK-pi(+)pi(-) and favored B- -> D pi(-)pi(+)pi(-) decays, where the neutral D meson is detected through its decays to the K--/+pi(+/-) and CP -even K+K- and pi(+)pi(-) final states. The measurement is carried out u ...

Evidence for the Suppressed Decay B- -> DK-, D -> K+pi-

Olivier Schneider, Chao Wang, Tagir Aushev, Vladislav Balagura, Jean Wicht, Remi Léandre Albert Louvot, Jing Li

The suppressed decay chain B- -> DK-, D -> K+pi(-), where D indicates a (D) over bar (0) or D-0 state, provides important information on the CP-violating angle phi(3). We measure the ratio R-DK of the decay rates to the favored mode B- -> DK-, D -> K+pi(-) ...

We present a new measurement of the unitarity triangle angle phi(3) using a Dalitz plot analysis of the K-S(0)pi(+)pi(-) decay of the neutral D meson produced in B-+/- -> D-(*()) K-+/- decays. The method exploits the interference between D-0 and (D) over b ...

One light composite Higgs boson facing electroweak precision tests

Marc Gillioz

We study analytically and numerically the bounds imposed by the electroweak precision tests on a minimal composite Higgs model. The model is based on spontaneous SO(5) -> SO(4) breaking, so that an approximate custodial symmetry is preserved. The Higgs ari ...
