  1. Higgs Mass: Test to be done

  2. Momentum measurement • Study with Z • Delta M Data vs MC in the largest possible Pt range • Delta Pt (ID-MS and ID-CB) Data vs MC in the largest possible range (split also for charge: Misalignment) Energy loss ( eta bins) . • Study the absolute value of the Mass measurement with Z • Determine the effect of the MCP corrections • Study with j/psi and Y • Same as for the study with Z • Understand if there is coherency in the overlap region • Determine the effect of local misalignment in different Pt range.

  3. Momentum measurement • What is the effect of different alignment on the Higgs and Z mass • Reprocess Higgs candidates with different alignment (present Tier0, last Christoph alignment after validation) • Reprocess Z candidates with different alignements as above • Study the q*Delta M/M with different alignment scenario • Reprocess Z events removing the Z correlation in staco and check in the misaligned regions the effect of the modified staco on the signed Z mass. (validation of the study of Rosy on Higgs candidates • Calculate pulls between momentum measurement with ID, CB, Cb modified and MS for Higgs candidates • Calculate Pulls on mass for Higgs candidates • How well we know the Magnetic field also local and global scale. • Energy loss fluctuation • Multiple Scattering

  4. FSR and Higgs modeling • Check all candidates with Event Display, check for photons • Finalize systematic studies on the FSR • Use real Z events to generate pseudo-experiments and check with MC to see if distribution tails are compatible, Calculate pulls • Pseudo-experiments with Higgs MC to assess the statistical error and the systematic shift of the measured mass. • Calculate per events mass error.
