At the LHC bunched proton proton collisions will occur at a centre of mass energy of 14 TeV, an order of magnitude greater than previously available. It has been shown that models predicting new heavy resonances decaying to electron-positron pairs may be detectable with a small data sample given the predicted clean event signature and low background. A search for such high mass events...

In the large extra dimensional ADD scenario, Z bosons undergo a one-loop decay into a photon and Kaluza-Klein towers of gravitons/gravi-scalars. We donsider the phenomenology of this decay, using LEP data to derive constraints on the size of such extra dimensions.

The study of neutralino decays provides valuable information on the underlying MSSM parameters. Contributions from Higgs boson exchange can play an important role in parts of parameter space, particularly in CP violating scenarios. The effect of loop corrections in the Higgs and chargino-neutralino sectors is also considered.

We consider the complex MSSM and examine whether and in which cases CP-violating phases will be observable at the LHC. We study Stop production and subsequent cascade decay into Neutralinos as the process for our investigation. It is found that asymmetries of up to 40% can be produced.

The trilepton signature is one of the 'golden' channels for SUSY due to its striking signature of three leptons and missing energy in the final state. The classic trilepton SUSY signature is gaugino pair production and decay via virtual Z and W bosons to three leptons, neutrinos and the LSP. The Tevatron collider at Fermilab has been looking for these events using proton-antiproton collisions...

It can be argued that in generic models of low scale supersymmetry breaking (where gravity effects can be neglected) metastability is inevitable. Accepting this fact allows one to build simple and concrete models of gauge mediated supersymmetry breaking. We exhibit a compact model of direct gauge mediation and its resulting MSSM phenomenology, which is able to interpolate between the standard...

We present recent developments in the Monte Carloevent generator Sherpa. An extension of the CKKW algorithm for merging Matrix Elements and Parton Showers to processes
including decays of heavy unstable particles is discussed.
New shower algorithms based on the Catani-Seymour subtraction
terms and dipole splitting functions are introduced.
A new Matrix Element generator for high...
