[Brahms-l] Minutes 20 Nov 09

Minutes of BRHAMS Analysis Meeting 20 Nov 2009
==============================================

Agenda:
http://indico.cern.ch/conferenceDisplay.py?confId=74751

Present: Kris, Flemming, Steve, Michael, Ramiro, JH and Chellis?


662GeV pp: Kris and  Flemming
=============================

Flemming has been looking at the forward pion and yields. They tend  
to have a different functional form that we are used to, ie they drop  
off faster at high Pt. He is also working on kaons. Werner Vogleshan  
has done pQCD calculations for this system. The k+ and k- spectra are  
much closer together than in the data.

Kris has worked a lot on fine tuning the stopping figure and  
superimposing the Pythia calculations. JH asked if there would be a  
discussion of limiting fragmention. Kris and Flemming will put their  
work together the week after Thanksgiving. Kris has also worked on  
the text.


Other Papers:
=============
Michael is working on the error discussion of the d/p paper. Casper  
has had swine flue but Michael will pester him to get the final plots  
before thankgiving.  Steve has


Romiro has reprocessed for forward spectrometer data for dA. For the  
vertex he plans to switch to just the projected track vertex. He has  
looked 12 degree data with H1 and it looks very different than with  
H2. Spectrum is much harder in H1 than in H2. This seems to be due to  
the poorer momentum resolution. He could try deconvoluting for the  
resolution or just keep to regions where p<2*p_reference.

JH says that he has made some progress on his asymmetry paper. He  
hopes to have it out before the end of the year.

Computer Upgrade:
=================
This will be the week after Thanksgiving for 1/2 a day. Root version  
will go to 5.22 and we will go to the next version of Scientific  
Linux. Do a Make Clean to clean up all objects.


Happy Thanksgiving, next meeting Dec 4th
