Energy consumption and jet multiplicity from the leading log BFKL evolution
We study the associated jet multiplicity arising from t–channel BFKL gluon
evolution in forward dijet production at hadron colliders. Previous results have shown that
the effect of conserving overall energy and momentum is to...
Double parton distributions incorporating perturbative QCD evolution and momentum and quark number sum rules
It is anticipated that hard double parton scatterings will occur frequently in
the collisions of the LHC, producing interesting signals and significant backgrounds to certain
single scattering processes. For double scattering...
The effect of leg-to-body ratio on male attractiveness depends on the ecological validity of the figures
Leg-to-body ratio (LBR) predicts evolutionary fitness, and is therefore expected to influence bodily attractiveness. Previous investigations of LBR attractiveness have used a wide variety of stimuli, including line drawings...
A new mechanism of strain transfer in polycrystals.
At the grain boundaries of plastically deforming polycrystals, strain transfer mechanisms can accommodate the shear strain carried by slip bands and mechanical twins to prevent stress build-ups and damage. So far, only the...
Uncertainties of predictions from parton distributions II
We determine the uncertainties on observables arising from the errors on the experimental
data that are fitted in the global MRST2001 parton analysis. By diagonalizing the
error matrix we produce sets of partons suitable for use...
Parton distributions for the LHC
We present the first determination of parton distributions of the nucleon at
NLO and NNLO based on a global data set which includes LHC data: NNPDF2.3. Our
data set includes, besides the deep inelastic, Drell-Yan, gauge...
Parton distributions incorporating QED contributions
We perform a global parton analysis of deep inelastic and related hard-scattering data,
including O( QED) corrections to the parton evolution. Although the quality of the fit is
essentially unchanged, there are two important...
Uncertainties of predictions from parton distributions - I
We study the uncertainties in parton distributions, determined in global fits to deep
inelastic and related hard scattering data, due to so-called theoretical errors. Amongst
these, we include potential errors due to the change...
Estimating Atomic Contributions to Hydration and Binding Using Free Energy Perturbation.
We present a general method called atom-wise free energy perturbation (AFEP), which extends a conventional molecular dynamics free energy perturbation (FEP) simulation to give the contribution to a free energy change from each...
Physical gluons and high-E-T jets
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 MS-scheme...
MRST partons generated in a fixed-flavour scheme
We generate fixed three- and four-light-flavour sets of partons using MRST2004 partons
as input. We show that it is important to set nf = 3 in the strong coupling, as
well as in the splitting and coefficient functions, in order...
