Hello Sebouh, Energy loss is not currently accounted for in the track fit.

I have been looking at the resolution of the SVT for reconstructing the A' invariant mass for muon events, and I have a question about the reconstruction software's internal workings: does it by default take into account energy loss and multiple scattering due to brehmstralung? I assume if so, then it is calibrated under the assumption that the particle is an electron. If this is the case, is there a way to either disable this feature or (better yet) have it make the assumption that the particle is a muon (so that I can get a more accurate measurement of the A' mass resolution)? thanks ________________________________ Use REPLY-ALL to reply to list To unsubscribe from the HPS-SOFTWARE list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1 ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the HPS-SOFTWARE list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1
