Exclusive vector meson production in heavy ion collisions (2019)
Journal Article
Khoze, V., Martin, A., & Ryskin, M. (2019). Exclusive vector meson production in heavy ion collisions. Journal of Physics G: Nuclear and Particle Physics, 46(8), Article 085002. https://doi.org/10.1088/1361-6471/ab2009

We discuss the salient features of exclusive vector meson production in heavy ion collisions at LHC energies. Special attention is paid to the space-time picture of the process. We account for both coherent and incoherent contributions. The explicit... Read More about Exclusive vector meson production in heavy ion collisions.

LHC searches for Dark Matter in compressed mass scenarios: challenges in the forward proton mode (2019)
Journal Article
Harland-Lang, L., Khoze, V., Ryskin, M., & Tasevsky, M. (2019). LHC searches for Dark Matter in compressed mass scenarios: challenges in the forward proton mode. Journal of High Energy Physics, 2019(4), Article 10. https://doi.org/10.1007/jhep04%282019%29010

We analyze in detail the LHC prospects at the center-of-mass enery of s√ = 14 TeV for charged electroweakino searches, decaying to leptons, in compressed supersymmetry scenarios, via exclusive photon-initiated pair production. This provides a potenti... Read More about LHC searches for Dark Matter in compressed mass scenarios: challenges in the forward proton mode.

Searching for the odderon in ultraperipheral proton-ion collisions at the LHC (2019)
Journal Article
Harland-Lang, L., Khoze, V., Martin, A., & Ryskin, M. (2019). Searching for the odderon in ultraperipheral proton-ion collisions at the LHC. Physical Review D, 99(3), Article 034011. https://doi.org/10.1103/physrevd.99.034011

We explore the possibility of observing odderon exchange in proton-ion collisions at the LHC, via the ultraperipheral photoproduction of C-even mesons. As well as the signal, we consider in detail the principle backgrounds, due to QCD-initiated produ... Read More about Searching for the odderon in ultraperipheral proton-ion collisions at the LHC.

Exclusive LHC physics with heavy ions: SuperChic 3 (2019)
Journal Article
Harland-Lang, L., Khoze, V., & Ryskin, M. (2019). Exclusive LHC physics with heavy ions: SuperChic 3. The European Physical Journal C, 79(1), Article 39. https://doi.org/10.1140/epjc/s10052-018-6530-5

We present results of the updated SuperChic 3 Monte Carlo event generator for central exclusive production. This extends the previous treatment of proton–proton collisions to include heavy ion (pA and AA) beams, for both photon and QCD-initiated prod...

Black disk radius constrained by unitarity (2018)
Journal Article
Khoze, V., Martin, A., & Ryskin, M. (2018). Black disk radius constrained by unitarity. Physics Letters B, 787, 167-170. https://doi.org/10.1016/j.physletb.2018.10.054

We argue that if the elastic proton–proton cross section increases with energy, the Froissart-like high energy behaviour of the elastic amplitude (which corresponds to a ‘black disk’ of radius R(s) = c ln s −βln(ln s)) is the only possibility to sati...

Elastic and diffractive scattering at the LHC (2018)
Journal Article

Inspired by the new TOTEM data on elastic pp scattering at 13 TeV, we study the possibility to describe all the diffractive collider data (, , ) in a wide interval of energy (0.0625 to 13 TeV) in the framework of a two-channel eikonal model. We show... Read More about Elastic and diffractive scattering at the LHC.

Multiple interactions and rapidity gap survival (2018)
Journal Article
Khoze, V., Martin, A., & Ryskin, M. (2018). Multiple interactions and rapidity gap survival. Journal of Physics G: Nuclear and Particle Physics, 45(5), Article 053002. https://doi.org/10.1088/1361-6471/aab1bf

Observations of rare processes containing large rapidity gaps at high energy colliders may be exceptionally informative. However the cross sections of these events are small in comparison with that for the inclusive processes since there is a large p... Read More about Multiple interactions and rapidity gap survival.

Black disk, maximal Odderon and unitarity (2018)
Journal Article
Khoze, V., Martin, A., & Ryskin, M. (2018). Black disk, maximal Odderon and unitarity. Physics Letters B, 780, 352-356. https://doi.org/10.1016/j.physletb.2018.03.025

We argue that the so-called maximal Odderon contribution breaks the ‘black disk’ behaviorof the asymp-totic amplitude, since the cross section of the events with Large Rapidity Gaps grows faster than the total cross section. That is the ‘maximal Odde... Read More about Black disk, maximal Odderon and unitarity.

Elastic proton-proton scattering at 13 TeV (2018)
Journal Article

The predictions of a model which was tuned in 2013 to describe the elastic and diffractive p p - and/or p ¯ p -data at collider energies up to 7 TeV are compared with the new 13 TeV TOTEM results. The possibility of the presence of an odd-signature O... Read More about Elastic proton-proton scattering at 13 TeV.

Total π + p cross section extracted from the leading neutron spectra at the LHC (2017)
Journal Article
Khoze, V., Martin, A., & Ryskin, M. (2017). Total π + p cross section extracted from the leading neutron spectra at the LHC. Physical Review D, 96(3), Article 034018. https://doi.org/10.1103/physrevd.96.034018

We use the very forward neutron energy spectra measured by the LHC forward experiment at 7 TeV to extract the πþp total cross section at center-of-mass energies in the range 2.3–3.5 TeV. To do this, we have to first isolate the π-exchange pole in for... Read More about Total π + p cross section extracted from the leading neutron spectra at the LHC.
