Particle physics has had remarkable success in describing collider data using usual Feynman diagram techniques, but little is understood regarding particles during the time of interaction. We use the Schwinger-Keldysh finite-time formalism applied to an interacting scalar field theory to derive a perturbative expression for the energy momentum tensor associated with hard particle production....

Even if the unification and supersymmetry breaking scales are around $10^6$ to $10^9$ TeV, a large $A_t$ coupling may be entirely generated at low energies through RGE evolution in the 5D MSSM. Independent of the precise details of supersymmetry breaking, we take advantage of power law running in five dimensions and a compactification scale in the 10 − $10^3$ TeV range to show how the gluino...

Oral
ALICE (A Large Ion Collider Experiment) is designed and optimized to
study ultra-relativistic heavy-ion collisions, where a hot and dense strongly-interacting medium is created. W± bosons are produced in hard scattering
processes occurring at the early stage of the collision and, not being affected by
the strong interaction, they can be used as a benchmark for medium induced
effects. In...
