The production of a diphoton resonance via photon-photon fusion.

Harland-Lang, L. A. and Khoze, V. A. and Ryskin, M. G. (2016) 'The production of a diphoton resonance via photon-photon fusion.', Journal of high energy physics., 2016 (3). p. 182.

Abstract

Motivated by the recent LHC observation of an excess of diphoton events around an invariant mass of 750GeV, we discuss the possibility that this is due to the decay of a new scalar or pseudoscalar resonance dominantly produced via photon-photon fusion. We present a precise calculation of the corresponding photon-photon luminosity in the inclusive and exclusive scenarios, and demonstrate that the theoretical uncertainties associated with these are small. In the inclusive channel, we show how simple cuts on the final state may help to isolate the photon-photon induced cross section from any gluongluon or vector boson fusion induced contribution. In the exclusive case, that is where both protons remain intact after the collision, we present a precise cross section evaluation and show how this mode is sensitive to the parity of the object, as well as potential CP-violating effects. We also comment on the case of heavy-ion collisions and consider the production of new heavy colourless fermions, which may couple to such a resonance.
