Probing new physics in diphoton production with proton tagging at the Large Hadron Collider
read the original abstract
The sensitivities to anomalous quartic photon couplings at the Large Hadron Collider are estimated using diphoton production via photon fusion. The tagging of the protons proves to be a very powerful tool to suppress the background and unprecedented sensitivities down to $6 \cdot 10^{-15}$\gev$^{-4}$ are obtained, providing a new window on extra dimensions and strongly-interacting composite states in the multi-TeV range. Generic contributions to quartic photon couplings from charged and neutral particles with arbitrary spin are also presented.

Magnetic Monopoles -- From Dirac to the Large Hadron Collider
Magnetic monopoles are theoretically well-motivated but remain unobserved after extensive searches in cosmic rays and at particle colliders such as the LHC.
