Physical Review D, 2016 We report on the possibility of reweighting parton-shower Monte Carlo predictions for scale variations in the parton-shower algorithm. The method is based on a generalization of the Sudakov veto algorithm. We demonstrate the feasibility of this approach using example physical distributions.

Elastic parton-parton scattering from AdS/CFT [PDF]
Physics Letters B, 1999 Using the AdS/CFT correspondence and the eikonal approximation, we evaluate the elastic parton-parton scattering amplitude at large $N$ and strong coupling $g^2N$ in N=4 SYM. We obtain a scattering amplitude with a Regge behavior that unitarizes at large $\sqrt{s}$.

The multidimensional nucleon structure
EPJ Web of Conferences, 2016 We discuss different kinds of parton distributions, which allow one to obtain a multidimensional picture of the internal structure of the nucleon.

Implementing potential climate‐smart practices through diverse partnerships
PLANTS, PEOPLE, PLANET, EarlyView.Climate change is one of the greatest threats to society, negatively impacting agriculture and crop yields. Globally, agriculture is also one of the largest greenhouse gas (GHG) emitting sectors. Climate‐smart practices that are developed through diverse partnerships with scientists and practitioners are needed to decrease GHG emissions. We implemented

Double Parton Interactions inp-Acollisions and Partonic Correlations [PDF]
EPJ Web of Conferences, 2015 The Double Parton Scattering dynamics is different in p-p and in p-A collisions. Their joint study of DPS in p-p and in p-A collisions can therefore provide valuable information on the non-perturbative input to the process, namely multi-parton correlations, which cannot be obtained by studying DPS in p-p only.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

A parton shower consistent with parton densities at LO and NLO: Pdf2Isr
European Physical Journal C: Particles and FieldsWe present a method for obtaining an initial-state parton shower model where the (backward) evolution fully consistent with the (forward) evolution of the collinear parton density used.

Organ‐specific ozone and nitrogen legacies strengthen substrate control over litter decomposition
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Elevated tropospheric ozone (O3) and nitrogen (N) deposition are concurrent atmospheric changes that strongly influence terrestrial carbon cycling, yet their combined effects on below‐ground decomposition remain poorly understood.
