1. Physics validation for EWK PAG
Physics validation for PAGs covers:
1. Validation of MC samples
I.e. checking that samples don’t show any gross errors
a. preproduction samples
b. full statistics samples
2. DQM for physics data
Current EWK contact to CMS Physics Validation Team (PVT): Monika Grothe
MC production validation:
Contributors to validation of September 09 preproduction from EWK:
Maria Cepeda for samples with muons
Thiago Tomei for W/Znjets Alpgen samples
Liis Rebane for samples with taus
Needed: All end-users of samples need to take responsibility in validating them
Quick turn-around in everybody’s interest, without preprod validation production
Of full statistics MC samples won’t go ahead

2. DQM for EWK PAG: The quickest and simplest way to look at data !
Already available in DQM offline GUI:
DQM/Physics/EWKMuDQM -- Maria Cepeda
Monitors effect in data of cuts of inclusive W/Z reconstruction in muon channel
Will go in with 3.5.x:
DQM/Physics/EWKMuLumiDQM -- Michele De Gruttola, Maria Cepeda
Plots of Z/W (transverse) mass spectra, which can be combined outside of DQM
for the purpose of measuring luminosity
Additional modules we aim to get in for 3.5.x:
EwkElecDQM -- Jessica Leonard, Monika Grothe
EWKTauDQM -- Letizia Lusito, Joshua Swanson
