ATLAS measurement of photon induced WW production in pp collisions — •Filip Nechansky — DESY, Zeuthen

The LHC is currently the largest hadron collider, where strong interaction between the colliding protons or ions results in a production of large number of energetic particles. Under special circumstances, however, there can be an interaction of the electromagnetic fields of the colliding particles, resulting in high energetic photon-photon interactions. These are characterized by a clean final state driven mainly by the electroweak force and provide an important probe of the electroweak sector.

This talk reports on the recent observation of the two photon interaction producing a WW final state measured by the ATLAS detector at the LHC. This process is identified by the presence of two leptons and no additional activity in the proximity of the interaction vertex. Beside the signal isolation, the estimation of the dominant backgrounds is discussed as well.
