This pull request is fully signed and it will be integrated in one of the next CMSSW_12_6_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_13_0_X is complete. This pull request will be automatically merged. |
PR description:
This PR introduces the Lorentz Angle (LA) Prompt Calibration Loop for the Pixel Forward Phase 1 detector (FPIX). In FPIX, LA is measured using the Minimal Cluster Size method.
The SiPixelLorentzAnglePCLWorker creates 16 2D cluster size x/y vs cot(alpha/beta) histograms and 8x3 magnetic field components histograms. In SiPixelLorentzAnglePCHarvesterMCS the cluster size x/y vs cot(alpha/beta) histograms are used to generate 1D profiles (average cluster size x/y vs cot(alpha/beta)) which are then fit and the values of the cot (alpha/beta) for which the cluster sizes are minimal are determined. The obtained cot(alpha/beta)_min value for z- and z+ side are used to perform fit to determine muH for different rings and panels of the Pixel Forward Phase 1 detector using the formulas:
cot(alpha)_min = vx/vz = (muHBy + muH^2xBzBx)/(1+muH^2Bz^2)
cot(beta)_min = vy/vz = -(muHBx - muH^2xBzBx)/(1+muH^2Bz^2)
