Figure 1: A schematic view of the forward region. The pair monitor will be located in front of the BeamCal, where is about 400 cm from IP. At ILC, measurement of the beam profile at IP is important to keep high luminosity of 2 × 10 cms. The beam size at IP is 639 nm, 5.7 nm, and 300 μm for horizontal (σX), vertical (σY), and longitudinal beam size (σZ),(More)
One of the key assumptions of the standard model of particle physics is that the interactions of the charged leptons, namely electrons, muons and taus, differ only because of their different masses. Whereas precision tests comparing processes involving electrons and muons have not revealed any definite violation of this assumption, recent studies of B-meson(More)
