MMHT Updates, LHC jets and α S (2018)
Presentation / Conference Contribution
Thorne, R., Harland-Lang, L., & Martin, A. (2018, December). MMHT Updates, LHC jets and α S. Presented at Proceedings of XXVI International Workshop on Deep-Inelastic Scattering and Related Subjects — PoS(DIS2018)

We summarise the effects of including jet data from the LHC in the MMHT PDF extraction. We also present the latest results on the preferred value of the strong coupling α S ( M 2 Z ) αS(MZ2) in a number of fit variations. The best current value with...

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
Khoze, V., Martin, A., & Ryskin, M. (2018). Elastic and diffractive scattering at the LHC. Physics Letters B, 784, 192-198. https://doi.org/10.1016/j.physletb.2018.07.054

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.

Open charm production and low x gluons (2018)
Journal Article
de Oliveira, E., Martin, A., & Ryskin, M. (2018). Open charm production and low x gluons. Physical Review D, 97(7), Article 074021. https://doi.org/10.1103/physrevd.97.074021

We compare the rapidity, y, and the beam energy, ffiffi s p , behaviors of the cross section of the data for D meson production in the forward direction that were measured by the LHCb Collaboration. We describe the observed cross sections using NLO p... Read More about Open charm production and low x gluons.

The impact of LHC jet data on the MMHT PDF fit at NNLO (2018)
Journal Article
Harland-Lang, L., Martin, A., & Thorne, R. (2018). The impact of LHC jet data on the MMHT PDF fit at NNLO. The European Physical Journal C, 78(3), Article 248. https://doi.org/10.1140/epjc/s10052-018-5710-7

We investigate the impact of the high precision ATLAS and CMS 7 TeV measurements of inclusive jet production on the MMHT global PDF analysis at next-to-next-to-leading order (NNLO). This is made possible by the recent completion of the long-term proj... Read More about The impact of LHC jet data on the MMHT PDF fit at NNLO.

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
Khoze, V., Martin, A., & Ryskin, M. (2018). Elastic proton-proton scattering at 13 TeV. Physical Review D, 97(3), Article 034019. https://doi.org/10.1103/physrevd.97.034019

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.
