Compare conversion and chi^2 methods for extracting yields

Updated on Fri, 2008-04-11 14:51. Originally created by jwebb on 2008-04-11 14:24.
Abstract:  We compare yields extracted using the EEmc Gammas via conversion method, systematics II with estimates based on a chi^2/ndf analysis of the SMD response.

Revised pythia estimates

Updated on Tue, 2008-04-08 21:43. Originally created by jwebb on 2008-04-08 19:25.
Abstract: I have Comparison with Cross Sections (Pythia estimates, prompt photon yields) shown projections for single photon yields in the pp2006 data which were flawed.  They overestimated the luminosity for a fixed sample size by a factor of ~3.  The problem was due to misinterpreting the definition of "tried" and "accepted" events in pythia 8.1.  New projections are presented for a cross check with yields extracted from data.

Yield estimates based on single-particle MC sample, and comparison w/ pythia.

Updated on Fri, 2008-04-11 10:45. Originally created by jwebb on 2008-04-08 15:52.
Abstract:  Based on EEmc Gammas via conversion method, retool from previous attempt at extracting yields, we generate a new MC sample.

SMD Band Structure - Tower Energy Correlation

Updated on Mon, 2008-04-07 16:44. Originally created by wleight on 2008-04-07 14:49.

To examine whether or not the appearance of band structure in the SMD response was correlated to the response of the towers overlapping with a given SMD strip, I filled a histogram of BSMDE strip i

EEmc Gammas via conversion method, retool

A few notes on previous studies.

1.0 Definition of D=log(Epost/Esmd) leads to "underflow" events when Epost=0.
