Elastic scattering and diffractive dissociation in the light of LHC data (2015)
Journal Article
Khoze, V., Martin, A., & Ryskin, M. (2015). Elastic scattering and diffractive dissociation in the light of LHC data. International Journal of Modern Physics A, 30(08), Article 1542004. https://doi.org/10.1142/s0217751x1542004x

We study the behavior of elastic and diffractive proton dissociation cross sections at high energy. First, we describe what would be expected to be observed at the Large Hadron Collider (LHC) based on conventional Regge theory. We emphasize the tensi...

Evolution in opening angle combining DGLAP and BFKL logarithms (2014)
Journal Article
de Oliveira, E., Martin, A., & Ryskin, M. (2014). Evolution in opening angle combining DGLAP and BFKL logarithms. The European Physical Journal C, 74(10), Article 3118. https://doi.org/10.1140/epjc/s10052-014-3118-6

We present an evolution equation which simultaneously sums the leading BFKL and DGLAP logarithms for the integrated gluon distribution in terms of a single variable, namely the emission angle of the gluon. This form of evolution is appropriate for Mo... Read More about Evolution in opening angle combining DGLAP and BFKL logarithms.

The photon PDF of the proton (2014)
Journal Article
Martin, A., & Ryskin, M. (2014). The photon PDF of the proton. The European Physical Journal C, 74(9), Article 3040. https://doi.org/10.1140/epjc/s10052-014-3040-y

We show how the photon input parton distribution function (PDF) may be calculated with good accuracy and used in an extended DGLAP global parton analysis in which the photon is treated as an additional point-like parton. The uncertainty of the input... Read More about The photon PDF of the proton.

BFKL equation for an integrated gluon density (2014)
Journal Article
de Oliveira, E., Martin, A., & Ryskin, M. (2014). BFKL equation for an integrated gluon density. The European Physical Journal C, 74(8), Article 3030. https://doi.org/10.1140/epjc/s10052-014-3030-0

We show how it is possible to rewrite the BFKL equation for the unintegrated gluon distribution, in terms of integrated gluons, similar to that used in DGLAP. We add to our equation the next-to-leading log terms which provide exact energy-momentum co... Read More about BFKL equation for an integrated gluon density.

High-energy elastic and diffractive cross sections (2014)
Journal Article
Khoze, V., Martin, A., & Ryskin, M. (2014). High-energy elastic and diffractive cross sections. The European Physical Journal C, 74(2), Article 2756. https://doi.org/10.1140/epjc/s10052-014-2756-z

We present a ‘global’ description of the wide variety of high-energy elastic and diffractive data that are presently available, particularly from the LHC experiments. The model is based on only one pomeron pole, but it includes multi-pomeron interact... Read More about High-energy elastic and diffractive cross sections.

High-energy strong interactions: from ‘hard’ to ‘soft’. (2011)
Journal Article
Ryskin, M., Martin, A., & Khoze, V. (2011). High-energy strong interactions: from ‘hard’ to ‘soft’. The European Physical Journal C, 71(4), Article 1617. https://doi.org/10.1140/epjc/s10052-011-1617-2

We discuss the qualitative features of the recent data on multiparticle production observed at the LHC. The tolerable agreement with Monte Carlos based on LO DGLAP evolution indicates that there is no qualitative difference between ‘hard’ and ‘soft’...

Bright matter-wave soliton collisions in a harmonic trap : regular and chaotic dynamics (2007)
Journal Article
Martin, A., Adams, C., & Gardiner, S. (2007). Bright matter-wave soliton collisions in a harmonic trap : regular and chaotic dynamics. Physical Review Letters, 98(2), https://doi.org/10.1103/physrevlett.98.020402

Collisions between bright solitary waves in the 1D Gross-Pitaevskii equation with a harmonic potential, which models a trapped atomic Bose-Einstein condensate, are investigated theoretically. A particle analogy for the solitary waves is formulated an... Read More about Bright matter-wave soliton collisions in a harmonic trap : regular and chaotic dynamics.

Physical gluons and high-ET jets (2004)
Journal Article
Martin, A., Roberts, R., Stirling, W., & Thorne, R. (2004). Physical gluons and high-ET jets. Physics Letters B, 604(1-2), 61-68. https://doi.org/10.1016/j.physletb.2004.10.040

We propose a more physical parameterization of the gluon distribution for global parton analyses of deep inelastic and related hard scattering data. In the new parameterization the gluon distribution at large x in the -scheme is driven by the valence... Read More about Physical gluons and high-ET jets.

We calculate g–2 of the muon and the QED coupling alpha(MZ2), by improving the determination of the hadronic vacuum polarization contributions and their uncertainties. We include the recently reanalyzed CMD-2 data on e+e–-->pi+pi–. We carefully combi... Read More about Predictions for g-2 of the muon and alpha(QED)(M(Z**2)).

We calculate (g-2)/2 of the muon, by improving the determination of the hadronic vacuum polarisation contribution, a_mu^{had,LO}, and its uncertainties. The different e+e- data sets for each exclusive (and the inclusive) channel are combined in order... Read More about The SM prediction of g-2 of the muon.

Unintegrated parton distributions (2001)

We describe how to calculate the parton distributions fa(x,kt2,μ2), unintegrated over the parton transverse momentum kt, from auxiliary functions ha(x,kt2), which satisfy single-scale evolution equations. The formalism embodies both DGLAP and BFKL co... Read More about Unintegrated parton distributions.

We evaluate, in a model-independent way, the signal-to-background ratio for Higgs→ b¯b detection in exclusive double-diffractive events at the Tevatron and the LHC. For the missing-mass approach to be able to identify the Higgs boson, it will be nece... Read More about Double-diffractive processes in high resolution missing-mass experiments at the Tevatron.
