CC Background Systematic 3 Philip Rodrigues Oxford Group Meeting 30/10/07
2 Introduction Shift in shower scale in Lauren’s horn on/horn off plots –MC was at higher E Could this be the reason for energy dependence in PID background method?
3 Method 1 As before: Plot some PID output for Near Det data and MC –Use NC selected events Scale true NC and true CC contributions to minimize c 2 Plot CC scale as a function of energy
4 Method 2 Scale MC shower energy: E → E’ = sE –Just amounts to a different binning in data and MC
6 NC Scales
7 Conclusions CC scale gets slightly flatter as a function of energy with shower energy scale change of ~2% NC scale not affected much
The Important Thing About By. The Important Thing About ******** The important thing about ***** is *****. It is true s/he can *****, *****, and *****.
Update on Data / MC Comparisons for Low Hadronic Energy CC-like Events Reminder of problem Fiducial studies with more MC statistics Effect of offset in.
Nue Working Group Plans 4 th June 2006 MINOS Collaboration Meeting Tufts University All sessions will be in Eaton 202 Connection information for those.
Tiles Method Divide variable plane into n x n tiles with (n-1) tile boundaries per variable n 2 observables: N ij (number of observed events in each tile)
Data/Monte Carlo disagreement for Rustem’s Signal Fluctuation variable in the Far Detector (Working Title) Philip Rodrigues Oxford MINOS Group Meeting.

CC PID Task Force Status Update Philip Rodrigues CC Phone Meeting 6 Dec 07.
NC Energy Estimators Philip Rodrigues. Issues Need to choose what true E to estimate. Options are: –showerEnergy –trueVisibleE –y*E_nu Need to choose.
Possible directions for NC sensitivity Philip Rodrigues April 2008 Minos collaboration meeting, Sussex.

THE COSTS OF PRODUCTION
HARP Anselmo Cervera Villanueva University of Geneva (Switzerland) K2K Neutrino CH Meeting Neuchâtel, June 21-22, 2004.
Expected Sensitivity of the NO A Disappearance Analysis Kirk Bays (Caltech) for the NO A Collaboration April 14, 2013 APS DPF Denver Kirk Bays, APS DPF.
Preparation Class for Physics Laboratory
T2K neutrino experiment at JPARC Approved since 2003, first beam in April Priorities : 1. search for, and measurement of, e appearance sin.
CC analysis progress This talk: –A first attempt at calculating CC energy sensitivity using the Far Mock data MC files with full reconstruction. –Quite.
1 Using the pHE data to measure the beam e ’s from + decay David Jaffe and Pedro Ochoa March 13 th 2007 Introduction Antineutrino selection Feasibility.
Selection: i) Used “basic cuts” described in my NuBarPID talk (slide 3). 74.4% of CC events pass this cut. ii) Used David’s PID cut at -0.2 to remove NC.
