We analyse in detail the role of additional hadron–hadron interactions in elastic photon– initiated (PI) production at the LHC, both in p p and heavy ion collisions. We first demonstrate that the source of difference between our predictions and other... Read More about Elastic photon-initiated production at the LHC: the role of hadron-hadron interactions.

Electromagnetically induced transparency in a V-system with 87Rb vapor in the hyperfine Paschen–Back regime (2021)
Journal Article

We observe electromagnetically induced transparency (EIT) in a V-system in a thermal rubidium-87 vapour in the hyperfine Paschen-Back regime, realised with a 0.6 T axial magnetic field. In this regime energy levels are no longer degenerate and EIT fe... Read More about Electromagnetically induced transparency in a V-system with 87Rb vapor in the hyperfine Paschen–Back regime.

We outline a strategy of how to search for QCD instantons of invariant mass 20–60 GeVin diffractive events in low-luminosity runs at the LHC. We show that, by imposing appropriate selection criteria on the final states, one can select the kinematic r...
