topic: fitting d0mq Data using MC histograms
comments: having 9-10 input parameters in the d0mq fit may be too many when using TMinuit class. Reducing the number of input parameters to 4-5 could be a help and this can be done by including the main background MCs such as bbbar and uds and combining all non-refmode ccbar MC to single 'not ccbar MC'. Histogram for ccbar radiative correction is also now included, too.

making Data and MC d0mq histograms are done by running
/home/jkim/run9 to /home/jkim/run12 (run14 will run all)

topic: fitting d0mq data with fewer parameters
comments: using fewer parameters to fit d0mq data could be a help to reduce chi2.

topic: shifting mean value in d0mq two-dimentional histogram
comments: using one-dimensional histogram, I have studied at which mean value shift of d0mq histogram the fitting is optimized. But since these mean value study was done using one-dimensional histgorams it could be different for two-dimensional histograms.

comments: mean value shift in equal-distance and equal-populated histogram could be different

topic: fitting d0mq data using equal-distance MC histograms
comments: fitting d0mq data using equal-distance MC histogram gave us worse chi2 and need more study

comments: even radiative correction is included signal region is not fitted well. Dr.Park suggested me to use RooFit to fit d0mq data using RooHistPdf class. Using RooFit or TMinuit will both use minuit, but RooFit is more user-friendly.

Feb 21 2011
topic: fitting resudial of d0mq data fitting comments: instead of including a gasussian in the first fitting with mean and rms value as input parameters, it would be faster to fit d0mq data without gaussian first, and then fit the residual with a gaussian

comments: by smoothing ccbar refmode MC only, chi2 is reduced by half.

comments: when applying raditive correction to pions in the refmode, it needs to be applied in the z direction momentum only, assuming pion is not going to change direction. When the correction is applied in the x and y direction, it in effect is applying the raditive correction more than once. With corrected radiative correction applied, the chi2 is now reduced to 2.5.

Feb 22 2011
topic: fitting d0mq data using MC histograms
comments: with radiation correction histogram where energy cut on two pions in ccbar refmode is applied, I was able to reduce the chi2 further, but now mean value shift in d0m is different and need more study

comments: Dr.Purohit suggested me to include a Gaussian in the d0mq two-dimensional fitting and see whether it is going to improve the fit. He also suggested to apply smoothing to a fraction of the ccbar signal MC thus it is going to widen its width a bit.

Feb 23 2011
topic: adding a gaussian in the d0mq fit
comments: since the fitting problem is in the ccbar signal region, adding a mathematical function such as a gaussian would be a help and indeed it does. With a gaussian added I was able to reduce the chi2 to 1.55.

Feb 24 2011
topic: fitting d0mq data with MC histograms including a radiative correction and a gaus
comments: Dr.Purohit suggested me to include a radiative correction, a gaus and fractional smoothing in MC histograms, but I realized that shfiting mean value of signal MC when a gaus is included is more effective to improve d0mq fitting and reduce chi2 to 1.141

comments: Dr.Park suggested me to rewrite my code in a more efficient way
* look page 30 in Dr.Park's root tutorial
* when including branch that exist in MC but not present in Data, use
if ( fChain->GetBranch("nBLYHit") ) fChain->SetBranchAddress("nBLYHit", &nBLYHit, &b_nBLYHit);
this way root is going to include this branch only when it exists

topic: calculating pull distributions
comments: when I was calculating pull distributions I was using a wrong equation. By definition pull should be
* pull=(Data-MC)/sqrt(eData*eData+eMC*eMC);

/susyraid1/home/jkim/analysis/15.8.0.2/CharmLv2NtupleMaker/babarReportRadcGaus/runall46


comments: Dr.Purohit suggested me to include one more gaussian in the d0mq fitting after looking at the pull distribution. He realized that the fitting in relatively not done well in the d0m peak region and he thinks by adding one more gaussian is going to help to reduce the chi2, but he also said too small chi2 is not good, either. He said chi2 close to 1 is the best case.

comments: while waiting for Hongxuan's email response for which cuts I need to include, I am going to see whether p* cut greater than 2.7 is going to help to reduce bbbar refmode contributions in the d0mq fitting. Since we do not have p* information in the ntuple, what we can do is first assume that the upsilon beam energy is a sum of electron and position energy in babar experiment and boost the refmode four vectors in the upsilon rest frame.

topic: applying pd0 cut in d0mq Data and MC
comments: since most refmodes in bbbar MC has low energies comapre to that in ccbar refmode, we can remove most of refmode coming from bbbar by applying a cut on tne momentum of d0 in beam rest frame. Dr.Purohit suggested me to apply pd0 in beam rest frame greater than 2.7 GeV

topic: applying pd0 cut in d0mq Data and MC
comments: in the beam rest frame I don't think we get a good seperation between ccbar and bbbar refmode in pd0 distribution. I need more study.

pd0 in lab and beam frame using ccbar and bbbar refmode MC: pd0mccut.pdf
/home/jkim/liuTmc30BinPd0/runall3

comments: when the pd0 is boosted in the opposite direction, we got a more reasonble result, where pd0 for bbbar refmode and non-refmode can be removed a lot. Since the total beam energy in the center of mass frame is 9.1 GeV and ccbar is couple to b and bbar thus producing cbbar and cbarb pairs and each pair is going to get same energy in the center of mass frame, the momentum of ccbar in the center of mass frame is less than 5 GeV for most events.

Mar 07 2011
topic: applying pd0 cut on d0mq data
comments: when a pd0 cut greater than 2.7 GeV is applied, we have left with 700k data. This cut could be a hard cut. I need to discuss this with Dr.Purohit.

d0mq one and two dimensional distributions pd0 not applied and applied with total entries quoted: pd0datav1.pdf
/home/jkim/liuDatav9/runall4

comments: when pd0 greater than 2.7 GeV cut is applied, we are left with 409594 in two-dimensional d0mq data. This is less than the signal yield what Liu was quoting in his note. Assuming that all events passed the pd0 cut is going to be identified as signal, I am still not going to get his signal yield. Maybe Liu was applied loose cut on pd0. I need to discuss this with Dr.Purohit.

comments: He mentioned in his email that he has cuts in refDisSigBkgd.cxx and I may need to implement these cuts in refModes.cxx

topic: reading skimmed ntuples
comments: since Liu already made skimmed ntuples, I can use these ntuples and fit data. But since he changed name of four vectors of reference modes, I need to ask him which one is which.

comments: entries in the d0m range using skimmed data ntuple is 4272337. But signal and background yield in one-dimensional d0m fitting is 530134 and 130488 with chi2=1.09 on Liu's bn page 118. I think there are a few selection cuts still need to be applied in the skimmed ntuple.

Mar 24 2011
topic: reading raw ntuples with a cut on pstar
comments: since disBet cut does not need to be applied to select reference mode, the only cut needs to be applied is a pstar cut on the raw ntuples I used to work with. But since peak region in data reference mode in Liu's fitting is identified as signal, I need to seperate ccbar partial and full match.

comments: since it is many-chain process to obtain ann cut, I would still use Hongxuan's source code at /susyraid1/home/liu/codes/skims but add particle ids and parent indices so that I can classify monte carlos as I want. Implementing ann routine in my own source code is another option.

comments: Dr.Park said it maybe necessary to apply kshort invariant mass cut on the reference and semileptonic modes so that we can eliminate combinatorial backgrounds

comments: Dr.Purohit and Dr.Park suggested me to
