Prof. Marek Karliner works on a range of topics in Quantum Chromodynamics, focusing on hadrons with heavy quarks. Specific topics include exotic hadrons, i.e. tetraquarks and pentaquarks, baryons with b quarks, as well as baryons containing two heavy quarks.
Research achievements include: accurate prediction of masses of baryons containing a single b quark, prediction of Z_b exotic states on the basis of anomalies in Belle experiment data, prediction of a charmed-anticharmed hadronic molecule subsequently discovered by LHCb at CERN, a highly accurate prediction of the mass of the lightest doubly-charmed baryon Xi_cc subsequently discovered by LHCb, a robust prediction for the first genuine tetraquark stable under strong interactions, (b b ubar dbar), quark-level analogue of nuclear fusion with doubly-heavy baryons, a proposal for using a future Higgs factory in radiative return mode as a high-luminosity QCD collider with CM energy above 12 GeV, discovery of spontaneous breaking of rotational symmetry in rotating solitons and emergence of hexagonal symmetry in 2+1 dimensional Skyrmion crystals.
Future directions include: utilizing the upcoming data from high luminosity pp, e+ e- and heavy ion colliders to search for and deepen the theoretical understanding of stable tetraquarks, doubly-heavy hadrons and new hadronic molecules.
