The changes are: * Tighten the track %$\chi^{2} / DOF$% cut from 6 to 3 on the protons. This cut should be applied offline anyway. * Tighten the %$p\overline{p}$% vtx %$\chi^{2}$% cut from 10 to 8. * Change prescale on the fake proton lines from 0.15 to 0.06 to keep within the rate. * Fix to include both sign of fake proton (take wrt to the muon) - previously we had only taken one which missed a large chunk. * Include 3 and 4 body TOPO HLT2 in the topo line. Ensure that the vtx %$\chi^{2}$% and track %$\chi^{2}$% are consistently applied to all the samples! ---++ Trigger https://gitlab.cern.ch/lhcb/Hlt/tree/2017-reference/Hlt/Hlt2Lines/python/Hlt2Lines/XcMuXForTau ---++ Data Location: ---+++ Run 1 for FF fit * 2011 -

Below are the rejection factors for the 2016 background MC samples. There are two factors which combine to make an overall rejection factor. One factor is the rejection due to any generator-level cuts, the second is due to the filtering (i.e. stripping in our case). The combined rejection factor here will be used to calculate the filtering factor for some of the decfiles used in the main R(pp) analysis in the table above. | Mode | Event type | Dec file | Gen-level | Filtering | Combined | | %$B\to p\Delta(\to pX)\mu\nu_{\mu}$% cocktail | 12813410 | Bu_Delpbarmunu,pX=TightCut.dec | 0.011725 | 0.1246 | 0.001461 | | %$B\to pN^{*}(\to pX)\mu\nu_{\mu}$% cocktail | 12813400 | Bu_pNstmunu,pX=TightCut.dec | 0.028915 | 0.1279 | 0.003698 | | %$B^{0}\to p\bar{p}DX$% | 11774000 | Bd_D0ppbar,Xmunu=DecProdCut.dec | 0.18612 | 0.02516 | 0.004683 | | %$B^{+}\to p\bar{p}D\mu\nu_{\mu}$% | 12572000 | Bu_D0ppmunu=TightCut.dec | 0.007997 | 0.1713 | 0.001370 | | %$B\to p\Lambda_{c}(\to pK\pi)\mu\nu_{\mu}$% | 12875010 | Bu_Lcpbarmunu,pKpi=TightCut.dec | 0.184705 | 0.02761 | 0.005100 | | %$B\to p\Lambda_{c}(\to pX)\mu\nu_{\mu}$% | 12875411 | Bu_Lcpbarmunu,pX=TightCut.dec | 0.028815 | 0.1214 | 0.003498 | | %$B\to N^{*}(\to \overline{p}X)\Lambda_{c}(\to pX)\mu\nu_{\mu}$% | 12675420 | Bu_LcNstmunu,pX=TightCut.dec | 0.007943 | 0.1265 | 0.001005 | | %$B\to p\Lambda_{c}^{*}\mu\nu_{\mu}$% | 12877400 | Bu_Lcpipipbarmunu,pX=TightCut.dec | 0.011603 | 0.1251 | 0.001452 | ---++ DEC files of interest The GEN level cuts on the background modes _should_ be: <blockquote> # tightCut.Cuts = {<br />#'[p+]cc' : " in_range( 0.010 , GTHETA , 0.400 )& ( GPT > 750 * MeV ) & (GP > 14600 * MeV)" ,<br />#'[mu-]cc' : " in_range( 0.010 , GTHETA , 0.400 ) & (GP > 2900 * MeV)"<br /># } </blockquote> | Mode | No | File | Comments | Outstanding Issues | GEN eff | Requested | Generated | | %$ \tau $% signal | 12513061 | Bu_ppmunu=DecProdCutpQCD | No GEN cuts - pQCD model | | %$19.5\pm1.8$% | 4M | | | %$\mu$% normalisation | 12513051 | Bu_pptaunu,mununu=DecProdCutpQCD | No GEN cuts - pQCD model | | %$16.1\pm1.6$% | 4M | | | %$\Delta$% cocktail | 12813412 | Bu_Delpbarmunu,pX=TightCutpQCD | GEN cuts - pQCD model | | %$3.3\pm0.4$% | | | | %$N^{*}$% cocktail | 12813402 | Bu_pNstmunu,pX=TightCutpQCD | GEN cuts - pQCD model | | %$4.7\pm0.5$% | | | | %$B^{0}\to p\bar{p}DX$% | 11876005 | [[https://gitlab.cern.ch/lhcb-datapkg/Gen/DecFiles/tree/v30r40/dkfiles/Bd_D0ppbarX,Xmunu=TightCut.dec][ *Bd_D0ppbarX,Xmunu=TightCut* ]] | GEN cuts | | %$4.7\pm0.5$% | | | | %$B^{+}\to p\bar{p}DX$% | 12775004 | [[https://gitlab.cern.ch/lhcb-datapkg/Gen/DecFiles/tree/v30r40/dkfiles/Bu_D+ppbarX,Xmunu=TightCut.dec][ *Bu_D+ppbarX,Xmunu=TightCut* ]] | GEN cuts | | %$4.6\pm0.5$% | | | | %$p\Lambda_{c}^{*}\mu\nu$% | 12877401 | Bu_Lcpipipbarmunu,pX=TightCut2.dec | GEN cuts | | %$3.1\pm0.3$% | | | | %$p\Lambda_{c}\mu\nu$%, %$\Lambda_{c}\to pX$% | 12875412 | Bu_Lcpbarmunu,pX=TightCut2.dec | GEN cuts | | %$4.4\pm0.4$% | | | | %$p\Lambda_{c}\mu\nu$%, %$\Lambda_{c}\to pK\pi$% | 12875010 | Bu_Lcpbarmunu,pKpi=TightCut.dec | only has acceptance %$\theta$% cuts | | | | | | %$p\Lambda_{c}\mu\nu$%, %$\Lambda_{c}\to pK^{0}\pi^{0}$% | ---- | | | | | | | | %$ppD\mu\nu$% | 12572001 | Bu_D0ppmunu=TightCut2.dec | GEN cuts need fixing plus more D modes | %$p_{T}$% cut on muon | | | | | %$B^{0} \to \Lambda_{c}pX$%, %$p\mu X$% | 11874110 | [[https://gitlab.cern.ch/lhcb-datapkg/Gen/DecFiles/tree/v30r40/dkfiles/Bd_LcpX,pmuX=TightCut.dec][ *Bd_LcpX,pmuX=TightCut* ]] | GEN cuts | | | | | | %$\Lambda_{b}\to \Lambda_{c}p\bar{p}\mu\nu$% | 15876401 | [[https://gitlab.cern.ch/lhcb-datapkg/Gen/DecFiles/tree/v30r40/dkfiles/Lb_Lcppbarmunu,pX=TightCut.dec][ *Lb_Lcppbarmunu,pX=TightCut* ]] | GEN cuts | | | | | ---++ MC efficiencies and estimated yields for Run 2 These numbers should be for the initial yields in the fit which will then add in the final selection efficiencies: Note this is a slight underestimate, particularly on the tau yield due to the muon pT cut. | *Mode* | *BK yield* | *Preselection Yield (strip + trig)* | *GEN/filter eff [%]* | *Stripping * Gen/filter eff [%]* | *Estimated yield after stripping* | *Assumptions* | *Angle cut eff [%]* | *Yield after angle cut* | | %$ \tau $% signal | 4,030,760 | 46,356 | 21.336 | 0.245 | 332.3 | %$R(pp) = 0.25$% | 74.2 | 246.6 | | %$\mu$% normalisation | 4,015,601 | 83,166 | 20.309 | 0.42 | 13093.92 | BF = %$6\times 10^{-6}$% | 81.1 | 10619.2 | | %$\Delta$% cocktail | 1,015,908 | 93,069 | 1.1709 | 0.107 | 3335.8 | BF = %$6\times 10^{-6}$% | 77.0 | 2568.6 | | %$N^{*}$% cocktail | 1,005,731 | 93,899 | 2.892 | 0.27 | 3335.8 | assume same as %$\Delta$% | 73.3 | 2445.1 | | %$B^{0}\to p\bar{p}DX$% | 1,000,388 | 10,045 | 18.61 | 0.19 | 89582 | %$BF(B\to ppD) = 13.96\times 10^{-4}$% of which 6.5% to %$X\mu$% | 25.1 | 22485.1 | | %$B^{+}\to p\bar{p}DX$% | | | | | | | | | | %$p\Lambda_{c}^{*}\mu\nu$% | 1,015,453 | 100,742 | 1.1552 | 0.114 | 17770 | %$BF(B\to\Lambda_{c}^{*}\mu\nu) = 2.5\times 10^{-4}$% with %$BF(\Lambda_{c}\to pX) = 12\%$% | 30.7 | 5455.39 | | %$ppD\mu\nu$% | 1,012,569 | 140,341 | 0.7998 | 0.11 | 10000 | ?

There are some more patches and speed gains to be found at<a href="https://twiki.cern.ch/twiki/bin/viewauth/LHCbPhysics/HistFactoryInfo" title="https://twiki.cern.ch/twiki/bin/viewauth/LHCbPhysics/HistFactoryInfo"> https://twiki.cern.ch/twiki/bin/viewauth/LHCbPhysics/HistFactoryInfo</a> The file that you want is 'Patches_May2017_ROOT-6.08.06.tar.gz'. The other versions seem to throw compilation errors. I have only tested the BB fix (HistFactoryModelUtils.cxx) - I couldn't get the other speed patches to work. ---++ Compiling ROOT ---+++ Mark's environment Compiling ROOT can be a bit of a pain. The compilers on slc6 are ancient so you need to point CMake in the direction of an LCG installation to use instead. Also make sure you enable all the options. * Extract the ROOT source code to some directory (i.e. ~/root_source) * In the source directory you need to alter the CMakeLists.txt to use a reasonably modern version of gcc and g++ by adding the following: * <blockquote> SET(CMAKE_C_COMPILER /cvmfs/lhcb.cern.ch/lib/lcg/releases/gcc/6.2.0binutils/x86_64-slc6/bin/gcc)<br />SET(CMAKE_CXX_COMPILER /cvmfs/lhcb.cern.ch/lib/lcg/releases/gcc/6.2.0binutils/x86_64-slc6/bin/g++) </blockquote> * You need to alter your PATH and LD_LIBRARY_PATH to pick up the correct libraries etc (note this is for C shell but I am sure you can figure it out for bash): * <blockquote> setenv PATH /cvmfs/lhcb.cern.ch/lib/lcg/releases/gcc/6.2.0binutils/x86_64-slc6/bin\:$PATH<br />setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH\:/cvmfs/lhcb.cern.ch/lib/lcg/releases/gcc/6.2.0/x86_64-slc6/lib64/\:/cvmfs/lhcb.cern.ch/lib/lcg/releases/gcc/6.2.0/x86_64-slc6/lib/\:/cvmfs/lhcb.cern.ch/lib/lcg/releases/gcc/6.2.0/x86_64-slc6/lib64/\:/cvmfs/lhcb.cern.ch/lib/lcg/releases/LCG_92/xrootd/4.7.0/x86_64-slc6-gcc62-opt/lib64 </blockquote> * Now copy in the code patches you wish to use (i.e. for HistFactory) * Make a new directory into which ROOT will be compiled (i.e. ~/myROOT) and cd into it. * Configure cmake * <blockquote> cmake -DAll=ON ~/root_source </blockquote> * Now you need to alter CMakeCache.txt so that it picks up the correct libraries for some things * <blockquote> //Path to a library.<br />XROOTD_XrdCl_LIBRARY:FILEPATH=/cvmfs/lhcb.cern.ch/lib/lcg/releases/LCG_92/xrootd/4.7.0/x86_64-slc6-gcc62-opt/lib64/libXrdCl.so<br /><br />//Path to a library.<br />XROOTD_XrdClient_LIBRARY:FILEPATH=/cvmfs/lhcb.cern.ch/lib/lcg/releases/LCG_92/xrootd/4.7.0/x86_64-slc6-gcc62-opt/lib64/libXrdClient.so<br /><br />//Path to a library.<br />XROOTD_XrdMain_LIBRARY:FILEPATH=XROOTD_XrdMain_LIBRARY-NOTFOUND<br /><br />//Path to a library.<br />XROOTD_XrdUtils_LIBRARY:FILEPATH=/cvmfs/lhcb.cern.ch/lib/lcg/releases/LCG_92/xrootd/4.7.0/x86_64-slc6-gcc62-opt/lib64/libXrdUtils.so<br /><br />//Dependencies for the target<br />XrdProofd_LIB_DEPENDS:STATIC=general;/cvmfs/lhcb.cern.ch/lib/lcg/releases/LCG_92/xrootd/4.7.0/x86_64-slc6-gcc62-opt/lib64/libXrdUtils.so;general;/cvmfs/lhcb.cern.ch/lib/lcg/releases/LCG_92/xrootd/4.7.0/x86_64-slc6-gcc62-opt/lib64/libXrdClient.so;general;/cvmfs/lhcb.cern.ch/lib/lcg/releases/LCG_92/xrootd/4.7.0/x86_64-slc6-gcc62-opt/lib64/libXrdCl.so;general;rpdutil;general;-lpthread;general;dl; </blockquote> * Now compile! * <blockquote> cmake --build . </blockquote> * At some point the compilation may segfault or throw some other fit.
