Two-photon decay of fully-charmed tetraquarks from light-by-light scattering at the LHC
Volodymyr Biloshytskyi, Lucian Harland-Lang, Bogdan Malaescu +3
The LHC newly-discovered resonant structures around 7 GeV, such as the , could be responsible for the observed excess in light-by-light scattering between 5 and 10 GeV. We…
Muonic-Atom Spectroscopy and Impact on Nuclear Structure and Precision QED Theory
Aldo Antognini, Sonia Bacca, Andreas Fleischmann +10
Recent progress in laser and x-ray spectroscopy of muonic atoms offers promising long-term possibilities at the intersection of atomic, nuclear and particle physics. In muonic hydr…
Theoretical discrepancies in the nucleon spin structure and the hyperfine splitting of muonic hydrogen
Vladimir Pascalutsa, Franziska Hagelstein, Vadim Lensky
Two groups, ours (Mainz) and Bochum, have recently been re-evaluating the spin polarizabilities and spin structure functions at low , using the baryon chiral perturbation theory…
Forward light-by-light scattering and electromagnetic correction to hadronic vacuum polarization
Volodymyr Biloshytskyi, En-Hung Chao, Antoine Gérardin +5
Lattice QCD calculations of the hadronic vacuum polarization (HVP) have reached a precision where the electromagnetic (e.m.) correction can no longer be neglected. This correction…
The two-photon decay of X(6900) from light-by-light scattering at the LHC
Volodymyr Biloshytskyi, Vladimir Pascalutsa, Lucian Harland-Lang +3
The LHCb Collaboration has recently discovered a structure around 6.9 GeV in the double- mass distribution, possibly a first fully-charmed tetraquark state . Based on…
Two-photon exchange in (muonic) deuterium at N3LO in pionless effective field theory
Vadim Lensky, Franziska Hagelstein, Vladimir Pascalutsa
We present a study of the two-photon-exchange (-exchange) corrections to the -levels in muonic (D) and ordinary (D) deuterium within the pionless effective field theory (…
