New and old Physics with Diphotons

Tuesday 20 Apr 2010, 14:30 → 17:30 Europe/Rome

Aula Bruno Touschek (Laboratori Nazionali di Frascati, Via Enrico Fermi 40, Frascati)

ABSTRACT

Prompt photons are both signatures and backgrounds for new physics and Higgs searches. From an experimental point of view, searches with final state photons have many advantages: photons couple to any particles with electric charge; they do not suffer a sensitivity loss from branching ratios; photon energy and direction are well measured. I will present results of a search for new physics with two photons and large missing transverse energy and a study of the prompt diphoton production in the context of Standard Model. I will also pay a special attention to experimental techniques.
