Early look at 2008 MIP peak

Updated on Tue, 2008-09-02 13:37. Originally created by mattheww on 2008-09-02 13:37.

The following plot shows the location in ADCs (pedestal subtracted) of the mip peak for each eta ring using pp data from day 47. The attached PDF shows the spectra for each ring and the fits.

Like-sign and unlike-sign asymmetry

Updated on Fri, 2008-08-29 14:39. Originally created by kurnadi on 2008-08-29 14:39.

In the ongoing effort to figure out what's wrong with my calculated 2005 asymmetries, the like-sign (A_ls) and unlike-sign (A_us) asymmetries, as defined

Normalization Procedure

I calculated the integrated luminosity for my dataset (5.43 pb^-1) and scaled all event- and jet-level histograms by that amount (in mb^-1 to match the partonic xsec numbers above). For the track histograms I added a multiplicative factor of 0.82 to account for imperfect PID efficiency in the data. I neglected PID contamination.
