Recent developments in perturbative QCD
Gavin P. Salam
A brief overview of some recently active topics in perturbative QCD, including: string-inspired recursion techniques at tree level; recursion approaches and automation of standard…
Infrared safe definition of jet flavour
Gavin P. Salam
Though it is widely taken for granted that it makes sense to separately discuss quark and gluon jets, normal jet algorithms lead to a net parton-level jet flavour that is infrared…
Automated Resummation and Hadron Collider Event Shapes
Gavin P. Salam
This writeup gives an introduction to the theoretical understanding that lies behind automated resummation. It then discusses its applications to hadron-collider event shapes.
HERA and the LHC - A workshop on the implications of HERA for LHC physics: Proceedings - Part A
S. Alekhin, G. Altarelli, N. Amapane +191
The HERA electron--proton collider has collected 100 pb of data since its start-up in 1992, and recently moved into a high-luminosity operation mode, with upgraded detectors…
Minimal Subtraction vs. Physical Factorisation Schemes in Small-x QCD
M. Ciafaloni, D. Colferai, G. P. Salam +1
We investigate the relationship of ``physical'' parton densities defined by kt-factorisation, to those in the minimal subtraction scheme, by comparing their small-x behaviour. We f…
Infrared safe definition of jet flavour
Andrea Banfi, Gavin P. Salam, Giulia Zanderighi
It is common, in both theoretical and experimental studies, to separately discuss quark and gluon jets. However, even at parton level, widely-used jet algorithms fail to provide an…
