− | === Determine Smearing ===
| |
− | * '''(select 8-38)''' Fit current BCAL time uncertainties for photons, pions, and protons: make sure they're similar to the uncertainties in David's studies.
| |
− | ** If they are not: probably due to clustering algorithm(s): '''ASSUME''' that the % of the timing uncertainty improvement is independent of this difference.
| |
| | | |
− | * '''(Waiting on results)''' Fit the BCAL time resolution improvement % from the table of David's results as a function of theta (separately for photons, pions, and protons). Energy-dependence comes from the coefficients.
| |
− |
| |
− | * '''(select 8-38)''' Separately generate single-track events of photons, pions, and protons with the BCAL time smearing disabled (generated at center of target: assume that this is what David did).
| |
− | * '''(Select)''' Determine time-smearing necessary to reach the improved time resolution, code smearing into BCAL shower reconstruction.
| |
− |
| |
− | === Physics Analysis ===
| |
− | * Smear TOF & FCAL time resolutions to reach design value (during reconstruction since already generated!)
| |
− | * Determine PID cuts for protons & pions (delta-beta vs p) for both smearing resolutions (use datasets generated earlier).
| |
− | ** sort beta vs p based on source: different timing widths from each source
| |
− | * '''(DONE)''' Generate b1pi events (all vertex z)
| |
− | * Two analyses: one with BCAL time smearing disabled (smear during shower reconstruction), the other with default smearing.
| |
− | * Run cooking code to reconstruct events.
| |
− | * Perform b1pi analysis, using PID cuts (allow all hypotheses).
