Backgrounds at CLIC
Апстракт
In this paper we discuss characteristics of physics and beam-induced backgrounds in luminosity calorimeter at the future Compact Linear Collider (CLIC) operating at the cms energy of 3 TeV. Presence of several sources of background is taken into account: SM four-fermion production, hadronic background and incoherent pairs converted from beamstrahlung photons. It has been concluded that by proper selection the presence of backgrounds in the luminosity calorimeter can be maintained at the upper limit of 10-3 w.r.t. signal. However, the main issue will be to define a region of the luminosity spectrum where the integral luminosity will be measured, since the luminosity spectrum is very strongly influenced by the beam-beam interaction related effects.
