Project description
New corrections can refine quantum chromodynamics
High-energy particle colliders like the Large Hadron Collider across the French-Swiss border allows one to study the production of mesons and baryons containing charm and bottom quarks on a widephase space. This requires the improvement of theoretical computations based on quantum chromodynamics in such unexplored regions. The EU funded RadCor4HEF project seeks to develop an efficient method to include these phase-space corrections, jointly using high-energy factorisation and collinear factorisation. The project will use a new computational framework to include sub-leading corrections in the strong-interaction coupling, applying it to the production of a variety of quarkonium mesons such as the eta (c,b), J/psi and Upsilon as well as charm and beauty hadrons. The goal is to understand the structure of protons and to predict heavy-quark-bound-state production.
Objective
"At High Energy hadron colliders, the wide phase space for particle emissions can compensate the smallness of the strong-interaction coupling of Quantum Chromodynamics (QCD). At the LHC this effect is crucial for production of mesons containing charm and bottom quarks. At hadron collider with energy of 100 TeV, all Standard Model physics will be affected by these large corrections.
RadCor4HEF's objective is to develop an efficient and robust method to match these phase-space corrections, provided by High-Energy Factorization (HEF) formalism with standard QCD computations in Collinear Factorization(CF). At present, this is not available. I aim at advancing the HEF including sub-leading corrections in the strong-interaction coupling within a new computational framework. I will apply it to study the production of (i) the eta_{c,b}-mesons in the LHCb kinematics, (ii) photoproduction of J/psi and Upsilon mesons (iii) hadroproduction of open heavy-flavour mesons.
For all of these observables the theoretical uncertainties are larger than the experimental ones and we will change this. The matched CF+HEF framework solves the instability problems of standard CF computations for eta_{c,b}, J/psi and open heavy flavour meson production at the LHC energies. RadCor4HEF will contribute to our quest to understand the proton structure and to predict heavy-quark bound-state production, which are the most poorly understood parts of QCD.
The science generated by RadCor4HEF will be disseminated via top-level publications, oral communications, outreach events and computing codes integrated in the EU Virtual Access ""NLOAccess"". Project activities will take place in the theory pole of IJCLab Orsay managed by CNRS, which gathers all the required expertise in the theory and phenomenology of QCD and particle physics. The exceptional environment part of Paris-Saclay U. will offer me an ideal training to develop my skills, to extend my research network and to become an independent researcher."
