Dear all,
I have checked the momentum resolution of muon for two angles with the new release (p = 1GeV/c, theta = 15deg and theta = 60 deg).
the result at Barrel region is normal, deltap/p = 1.56%, comparable to the result from TDR.
But, for the Forward region, I found deltap/p = 2.1%, very different from the TDR result which is about 1.5%.
Then, I also checked them with the apr13 release, both of them seem correct.
Has anyone some idea, why the momentum resolution in forward between apr13 and jan14 changes a lot?
