Hi all, those are few words in order to summarize the last days works. Production: recovered 600pb-1; Tot lumi available 80.3 fb-1, missing 1.6fb-1(to be investigated), duplicated runs (due tu recovey made twice) have been almost canceled (we still have 3 runs marked as duplicates but it was not easy to understand were are they coming from :(...). Mx study: -->Breakdown: refer to page http://www.slac.stanford.edu/~asarti/recoil/sys "I do not want you to go through all the plots and links" (most cited sentence in the past 3 weeks in vub-breco analysis group) so just few comments: 1) Now, I think, we have all the possible information about B semileptonic decays and D decays. The problem is: how are we going to use that information? After a brief discussion with Urs (thanks Urs) I've realized that all this knowledge still needs to be finalized ... I do NOT think that we're going to gain much implementing this breakdown in the fit of our depleted sample when we're running VubFit (add more categorizations of bakground on MC..) 2) A small comment about the most intresting plots.... Seems that even in the case when we have a long tail in lkow Mx region (see for example semileptonic B in D*) the cut on Mnu helps a lot. We can even tight this cut in order to higly suppress those tails and reduce the impact of those modes in our analysis but this of course needs to be seen in detail when we redo the optimization of cut looking at statistical error on Vub..... --> B0 and B+ eff. Take a look in http://www.slac.stanford.edu/~asarti/recoil/mx_stu I've produced eff. plots (data generic and data cocktail) for allB, B0 and B+..... I've started with the intention to look at two different effects: a) Mes fits in high mxhadfit region (they really have something screwed upo) b) improving agreement btw them by cutting on integrated purity/lepton momentum c) looking at the improvement with riccardo's proposal about photon cut I really apologize but a big problem in comparison code has bolcked me in the last two days (and han not yet been solved). Something is screwed up in the code I'm using to make the plots for the various comparisons (thecomaprison.C). I've looked into it (with Urs's help: thanks again) and we found some possible problems that still we need to understood (there's also a bug in the chisquare calculation that needs to be fixed). What I was able to do (mes plots.... and not much more) is in the web page. CU tomorrow at the meeting, Alessio ______________________________________________________ Alessio Sarti Universita' & I.N.F.N.
