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.

MMHT PDFs: Updates and Outlook (2017)
Journal Article
Harland-Lang, L., Nathvani, R., Thorne, R., & Martin, A. (2017). MMHT PDFs: Updates and Outlook. Acta Physica Polonica B, 48(6), 1011-1024. https://doi.org/10.5506/aphyspolb.48.1011

We present the latest results of studies within the MMHT PDF framework. We discuss the impact of the most recent ATLAS 7 TeV jet data, demonstrating that while a good fit can be achieved for individual jet rapidity bins, it is not possible to achieve...

Optimal choice of factorization scales for the description of jet production at the LHC (2017)
Journal Article

To obtain more precise parton distribution functions (PDFs) it is important to include data on inclusive high transverse energy jet production in the global parton analyses. These data have high statistics and the NNLO terms in the perturbative QCD (... Read More about Optimal choice of factorization scales for the description of jet production at the LHC.

Scale dependence of open cc¯ and bb¯ production in the low x region (2017)
Journal Article

The ‘optimal’ factorization scale μ0μ0 is calculated for open heavy quark production. We find that the optimal value is μF=μ0≃0.85p2T+m2Q−−−−−−−√μF=μ0≃0.85pT2+mQ2 ; a choice which allows us to resum the double-logarithmic, (αslnμ2Fln(1/x))n(αsln⁡μF2l...

Exclusive J=ψ production at the LHC in the kT factorisation approach (2017)
Journal Article

The recent LHCb data for exclusive J y peripheral production at 13 TeV motivate an improved ‘NLO’ analysis to estimate the gluon distribution at low x in which we re-calculate the rapidity gap survival factors and use a more precise expression for th...
