We propose a model-independent and general framework to study the LHC phenomenology
of top partners, ie vector-like quarks including particles with different electromagnetic …

We propose an experiment (Mu3e) to search for the lepton flavour violating decay mu+-> e+
e-e+. We aim for an ultimate sensitivity of one in 10^ 16 mu-decays, four orders of magnitude …

A bstract Motivated by the shift in experimental attention towards electroweak super-
symmetric particle production at the CERN LHC, we update in this paper our precision …

A bstract The 2011 dataset of the CMS experiment, consisting of an integrated luminosity of
4.98 fb− 1 of pp collisions at\(\sqrt {s}= 7\) TeV, enables expanded searches for direct …

A bstract How light can a fermion be if it has unit electric charge? We revisit the lore that LEP
robustly excludes charged fermions lighter than about 100 GeV. We review LEP chargino …

Direct searches for electroweak pair production of new particles at the LHC are a difficult
proposition, due to the large background and low signal cross sections. We demonstrate …

A bstract We investigate the current status of the light neutralino dark matter scenario within
the minimal supersymmetric standard model (MSSM) taking into account latest results from …

Lepton Flavour Violation in the charged lepton sector (CLFV) is forbidden in the Minimal
Standard model and strongly suppressed in extensions of the model to include finite …

We re-assess the exclusion limits on the parameters describing the supersymmetric (SUSY)
electroweak sector of the MSSM obtained from the search for direct chargino–neutralino …

A bstract We investigate the LHC sensitivity to supersymmetric models with light higgsinos,
small R-parity breaking and gravitino dark matter. The limits on decaying gravitino dark …
