Photon-initiated processes at high mass (2016)
Journal Article
Harland-Lang, L., Khoze, V., & Ryskin, M. (2016). Photon-initiated processes at high mass. Physical Review D, 94(7), Article 074008. https://doi.org/10.1103/physrevd.94.074008

We consider the influence of photon-initiated processes on high-mass particle production. We discuss in detail the photon parton distribution function (PDF) at relatively high parton x, relevant to such processes, and evaluate its uncertainties. In p...

Sudakov effects in photon-initiated processes (2016)
Journal Article
Harland-Lang, L., Khoze, V., & Ryskin, M. (2016). Sudakov effects in photon-initiated processes. Physics Letters B, 761, 20-24. https://doi.org/10.1016/j.physletb.2016.08.004

We consider the effect of the Sudakov factor in photon-initiated processes, corresponding to the no branching probability for the initial-state photon. We demonstrate how such a factor follows simply from the solution of the DGLAP equation for the ph... Read More about Sudakov effects in photon-initiated processes.

The photon PDF in events with rapidity gaps (2016)
Journal Article
Harland-Lang, L., Khoze, V., & Ryskin, M. (2016). The photon PDF in events with rapidity gaps. The European Physical Journal C, 76(5), Article 255. https://doi.org/10.1140/epjc/s10052-016-4100-2

We consider photon-initiated events with large rapidity gaps in proton–proton collisions, where one or both protons may break up. We formulate a modified photon PDF that accounts for the specific experimental rapidity gap veto, and demonstrate how th... Read More about The photon PDF in events with rapidity gaps.

Two scales in Bose–Einstein correlations (2016)
Journal Article
Khoze, V., Martin, A., Ryskin, M., & Schegelsky, V. (2016). Two scales in Bose–Einstein correlations. The European Physical Journal C, 76(4), Article 193. https://doi.org/10.1140/epjc/s10052-016-4055-3

We argue that the secondaries produced in high-energy hadron collisions are emitted by small-size sources distributed over a much larger area in impact parameter space occupied by the interaction amplitude. That is, Bose–Einstein correlation of two e... Read More about Two scales in Bose–Einstein correlations.

The production of a diphoton resonance via photon-photon fusion (2016)
Journal Article
Harland-Lang, L., Khoze, V., & Ryskin, M. (2016). The production of a diphoton resonance via photon-photon fusion. Journal of High Energy Physics, 2016(3), Article 182. https://doi.org/10.1007/jhep03%282016%29182

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 fusio...

Exclusive physics at the LHC with SuperChic 2 (2016)
Journal Article
Harland-Lang, L., Khoze, V., & Ryskin, M. (2016). Exclusive physics at the LHC with SuperChic 2. The European Physical Journal C, 76(1), Article 9. https://doi.org/10.1140/epjc/s10052-015-3832-8

We present a range of physics results for central exclusive production processes at the LHC, using the new SuperChic 2 Monte Carlo event generator. This includes significant theoretical improvements and updates, most importantly a fully differential... Read More about Exclusive physics at the LHC with SuperChic 2.
