Simulation Study of Beam Calorimeters in ILC

ILC(International Linear Collider) is a next generation electron-positron linear collider. It is expected to run with an initial center-of-mass energy of 200-500 GeV. GLD is a general-purpose detector designed for ILC.
In the very forward region, there are beam calorimeters.
These calorimeters provide hermeticity down to 5 mrad.

In ILC, there is an important background called eamstrahlung.
During the collision, beams will deflect and emit beamstrahlung photons and these photons will also interact with beam particles. These backgrounds will affect detectors in the very forward region.
Beam calorimeters recieve serious background from eamstralung backgrounds.
In this thesis, properties of beam calorimters and
beamstrahlung effect on the beam calorimeters are studied
based on the Monte Carlo simulation.
The search of supersymmetric particle smuon with the consideration of beam calorimeters and beamstrahlung is also presented in this thesis.
