The Proton Beam at the Large Hadron Collider (LHC)at CERN

Multiple Choice

The proton beam at the Large Hadron Collider (LHC) at CERN can reach a luminosity of 10³⁴ cm^-2s^-1 (this means that in a 1 cm² area,10³⁴ protons encounter each other every second) .A cross section for collisions of the order of 1 pb (picobarn) provided evidence of the Higgs boson.If the accelerator runs without interruption,approximately how many of these Higgs events can one expect in one year at the LHC?

A) 3 * 10⁵ Higgs events per year
B) 1 * 10⁴ Higgs events per year
C) 400 Higgs events per year
D) 6 * 10⁶ Higgs events per year
E) 2000 Higgs events per year
