Low x gluons determined by open charm production
E. G. de Oliveira, A. D. Martin, M. G. Ryskin
We use the LHCb data on the forward production of mesons at 7, 13 and 5 TeV to make a direct determination of the gluon distribution, , at NLO in the $10^{-5} \lesssim x \l…
Scale dependence of open and production in the low region
E. G. de Oliveira, A. D. Martin, M. G. Ryskin
The `optimal' factorization scale is calculated for open heavy quark production. We find that the optimal value is ; a choice which all…
Exclusive J/psi and Upsilon photoproduction and the low x gluon
S. P. Jones, A. D. Martin, M. G. Ryskin +1
We discuss the potential to constrain the small- PDFs using the exclusive production of heavy vector mesons. The calculation of and photoproduction at NLO in collinear…
Probes of the small x gluon via exclusive J/psi and Upsilon
S. P. Jones, A. D. Martin, M. G. Ryskin +1
New, more precise data on diffractive J/psi photoproduction and on exclusive J/psi production in the process pp -> p + J/psi + p at the LHC allow a better constraint on the low-x g…
The LHC can probe small x PDFs; the treatment of the infrared region
A. D. Martin, E. G. de Oliveira, M. G. Ryskin
First, we show how to reduce the sensitivity of the NLO predictions of the Drell-Yan production of low-mass, lepton-pairs, at high rapidity, to the choice of factorization scale. I…
New Physics at the LHC. A Les Houches Report: Physics at TeV Colliders 2009 - New Physics Working Group
G. Brooijmans, C. Grojean, G. D. Kribs +57
We present a collection of signatures for physics beyond the standard model that need to be explored at the LHC. First, are presented various tools developed to measure new particl…
Small x gluon from exclusive J/psi production
A. D. Martin, C. Nockles, M. Ryskin +1
Exclusive J/psi production, gamma* p -> J/psi p, offers a unique opportunity to determine the gluon density of the proton in the small x domain. We use the available HERA data to d…
Azimuthal decorrelation of forward and backward jets at the Tevatron
J. Kwiecinski, A. D. Martin, L. Motyka +1
We analyse the azimuthal decorrelation of Mueller-Navelet dijets produced in the collisions at Tevatron energies using a BFKL framework which incorporates dominant subleading effec…
Q^2 dependence of diffractive vector meson electroproduction
A. D. Martin, M. G. Ryskin, T. Teubner
We give a general formula for the cross section for diffractive vector meson electroproduction, gamma^* p -> Vp. We first calculate diffractive qqbar production, and then use parto…
The R ratio in e+ e-, the determination of alpha(Mz^2) and a possible non-perturbative gluonic contribution
A. D. Martin, J. Outhwaite, M. G. Ryskin
We review the determination of the QED coupling at the Z pole, which is a crucial parameter for electroweak theory. We include recent e+e- -> hadron data from Novosibirsk and Beiji…
The effect of off-diagonal parton distributions in diffractive vector meson electroproduction
A. D. Martin, M. G. Ryskin
We present a simple physical description of the off-diagonal gluon distribution g (x,x^\prime,Q^2) and splitting function P_{gg}(x,x^\prime) which enter the amplitude for diffracti…
