Multi-prong improved data selection (trigger-detector-less data acquisition, deadtime-free frontend electronics, Field Programmable Array (FPGA) based online selection) plus distributed physics analysis (partial wave analysis of resonances, and multi-particle correlations) for rare signal events under high background conditions (multi-PByte/month) in anti-p-p, anti-p-A, and A-A collisions for the PANDA and CBM experiments at the future FAIR facility.

Extraction of high-precision nuclear parton distribution functions (nPDF) through global fits including the latest LHC p-A and A-A data. Extension of current gluon-saturation calculations (CGC, BFKL, TMD...) to NLO accuracy with resummation corrections, for observables with three jets and with heavy-quarks. Calculation of multi-particle correlations issuing from initial-state PDF effects to separate them from final-state hydrodynamic effects in small systems (p-p, p-A collisions).

Development of novel experimental and theoretical techniques for jet physics in A-A collisions, providing a reference implementation of jet interactions in a QGP via a full heavy-ion Monte Carlo (MC) event generator. Definition of new observables and development of new tools (based on quark/gluon jet substructure variables via machine-learning techniques) with increased sensitivity to the physical mechanisms involved in jet-QGP interactions.

Address the “proton-radius puzzle” via combined data-theory analyses of new results in atomic spectroscopy (laser spectroscopy of Hydrogen molecules and molecular ions, muonic atoms, He+ ions, positronium, and muonium) and very-low momentum transfer (Q2) lepton-proton elastic scattering at various energies.

Address the “neutron stars hyperon puzzle” (contradiction between the observation of 2-solarmasses neutron stars and microscopical predictions of a softening of the nuclear equation-of-state due to the presence of strange-quark hadrons) through combined theoretical and experimental studies of (anti)hypernuclei and bound strange-meson systems produced in hadronic collisions at various c.m. energies.

Development of combined software, data sharing, and methodologies in lattice QCD theory across Europe along 4 axes: (i) hadron spectroscopy and structure, (ii) hadrons under extreme conditions, (iii) hadrons in the SM and beyond, (iv) novel numerical algorithms and computing for lattice hadron physics.

Extraction of QGP transport coefficients from new high-precision theoretical calculations and experimental measurements of the production of open and closed heavy flavour (HF) quarks (charm and beauty) in A-A collisions at the LHC. Accurate measurements of total c-cbar, b-bbar cross sections in p-p, p-A and A-A collisions. Development of a new data-theory interface (with a Rivet-like standard format) to compare event-byevent experimental results to MC predictions.
