Special Seminar: Forward Physics Facility @ CERN: The Astroparticle Connection

• Subir Sarkar (University of Oxford)
• Subir Sarkar (Saha Institute of Nuclear Physics (IN))

There is a renaissance of neutrino physics at CERN with the detection of TeV energy neutrinos from the colliding beams at the LHC by the FASER & SND detectors. There is much exciting physics that can be done at the proposed Forward Physics Facility of direct relevance to astroparticle physics experiments like cosmic neutrino telescopes and cosmic ray air shower arrays. I will discuss relevant topics such as neutrino interactions, forward charm & light hadron production and searches for new physics beyond-the-Standard-Model.

Landscape of the QCD Vacuum

We found new solutions of the sourceless Yang-Mills equation describing the superposition of chromomagnetic vortices of oppositely oriented magnetic fluxes. These gauge field configurations have constant energy densities and are separated by potential barriers forming a complicated landscape. It is suggested that the solutions describe the condensate of chromomagnetic vortices and represent a dual analog of the Cooper pairs condensate in a superconductor. In the presence of an Abelian field and in a particular limit the solutions reduce to flat connections of zero energy density and are forming a complicated potential landscape of the QCD vacuum. A possible tunnelling transition between these superfluxon flat configurations and the flat configurations with non-vanishing Chern-Pontryagin index will wash out the CP violating 𝜃 angle to zero, dynamically restoring CP symmetry.
