Title:          J/psi and D meson production in ZEUS, CMS, LHCb and ALICE (Open) Data

DESY group:     CMS

Type:           Tandem: Online (Remote) part

Duration:       19th july - 10th sep 2021

Description:    The study of open and hidden charm production in ep and pp collisions is one of the means to understand 
                Quantum Chromodynamics (QCD) at the boundary of the perturbative and nonperturbative regimes.
                Both the ZEUS common ntuples and the CMS nanoAODplus ntuples contain muons from J/psi decays and charm 
                mesons in similar formats which can straightforwardly be translated into each other. Doing such a 
                translation allows a common analysis and direct comparison of the resulting distributions with the same 
                analysis code.
                The first (simpler) goal is to prepare the tools to be able to read the ZEUS, CMS nad LHCb (possibly also 
                ALICE) data with the same code, to use these tools to produce corresponding kinematic distributions, 
                and to draw conclusions from their comparison at reconstruction level.
                The second (more ambitious) goal is to add simulations where available, derive corresponding cross sections, 
                and discuss what one can learn from these concerning QCD.


Special Qualifications expected:
No previous knowledge necessary (learning on the job). Previous knowledge of ROOT, C++, linux as well as basic 
knowledge of particle and/or detector physics would be an advantage.

Cancellation policy: In case the on-site part is cancelled due to COVID pandemic restriction
this online (remote) part of the project will still take place.
