TupleToolSemiLeptonic

This project provides several additional classes for the LHCb Analysis/Phys/DecayTreeTuple package for some semileptonic analyses.

Coding style

All .cpp and .h source files have been reformatted by:

clang-format -i -style=file *.cpp *.h

for visual consistency.

The formating template is located under .clang-format in the root directory of the project.

Installation on lxplus

Type these commands in your terminal:

lb-dev DaVinci/<version> && cd DaVinciDev_<version>
git lb-use TupleToolSemiLeptonic https://github.com/umd-lhcb/TupleToolSemiLeptonic.git
git lb-checkout TupleToolSemiLeptonic/master Phys/TupleToolSemiLeptonic
make configure && make

Local development

If you want to modify this TupleTool and run a local ntupling job with lhcb-ntuples-gen you will need to set up a new DaVinci inside docker with all the dependencies we use in our reco script. The workflow would be

cd lhcb-ntuples-gen
make docker-dv ## Enter Docker
export DAVINCI_VERSION=v45r6
export PHYS_VERSION=v26r6
export TUPLETOOL_SL_VERSION=0.2.4
export TRACKER_ONLY_EMU_VERSION=0.2.2

# Setup a DaVinci dev
source /usr/local/bin/envset.sh
git config --global user.name "Physicist"
git config --global user.email "[email protected]"
lb-dev DaVinci/${DAVINCI_VERSION}
git clone https://github.com/umd-lhcb/TrackerOnlyEmu.git --branch ${TRACKER_ONLY_EMU_VERSION} --depth 1
cd DaVinciDev_${DAVINCI_VERSION}
git lb-use Phys
git lb-checkout Phys/${PHYS_VERSION} Phys/LoKiPhys
git lb-checkout Phys/${PHYS_VERSION} Phys/DaVinciTypes
git lb-checkout Phys/${PHYS_VERSION} Phys/RelatedInfoTools
git lb-use TupleToolSemiLeptonic https://github.com/umd-lhcb/TupleToolSemiLeptonic.git
git lb-checkout TupleToolSemiLeptonic/${TUPLETOOL_SL_VERSION} Phys/TupleToolSemiLeptonic
cp -r ../TrackerOnlyEmu/davinci/* .

## Now you can edit the source code in lhcb-ntuples-gen/DaVinciDev_v45r6/Phys/TupleToolSemiLeptonic/src

# Compile DaVinci
make configure && make

# Run ntupling job
cd ../run2-rdx
..//DaVinciDev_v45r6/run gaudirun.py conds/cond-std-2016.py ./reco_Dst_D0.py

If you git annex get the required .DST files, this will produce a sample std.root in the run2-rdx folder.

It is highly recommended to use a docker with DaVinci and CLion shipped. It has smart auto-completion and detects errors on-the-fly. To use the docker:

docker run --rm -it -v $(pwd):/data \
    -v $HOME/.config/clion-java:/home/physicist/.java \
    -v $HOME/.config/clion:/home/physicist/.CLion2019.2 \
    -v $XAUTHORITY:/home/physicist/.Xauthority \
    -e DISPLAY -e UID=$(id -u) -e GID=$(id -g) \
    --net=host \
    umdlhcb/lhcb-stack-cc7:DaVinci-v45r4

Note that the clion folder stores IDE configuration, and clion-java folder store the licensing ticket.

Acknowledgment

This repository is a superset of SemileptonicCommonTools, with additional tools coming from B02DplusTauNu analysis. We made some changes and ported them to DaVinci/v45, the recommended version for all run 1 and 2 analyses.
