Question

Definition of relative luminosity physics

Answer 1

 bunches, "opposite" are "+-" and "-+" ● R is the relative luminosity ○ because it is a ratio, we can construct it from measured counts in any detector that sees no spin asymmetry We use our minimum bias BBC (Beam Beam Counter) to measure R ○ ...and compare it with a detector past the DX magnetic field ■ ZDC: Zero Degree Calorimeter, no charged particles ○ We then assume the different physics they sample can't have the same asymmetry ○ Compare the two results to get the systematic

Answer 2
