QCD and LHC phenomenology

Abstract

A very general algorithm has been developed for computing observables in particle collisions. This algorithm has been proven correct to a non-trivial order in perturbation theory. The project will focus on studying this algorithm and building up a computer code to implement it. This will first be done for simple prototype processes and then built up to ultimately compute any observable. The algorithm will sum all leading logarithms of soft and/or collinear origin.

Description Collaborative work in improving the CVolver codebase. 
Organisation University of Vienna
Country Austria 
Sector Academic/University 
PI Contribution Following on from the section "Briefly describe the contributions made by your partners to this collaboration or partnership.": I have collaborated with Simon to improve this codebase to implement the FKS algorithm developed originally in the paper arXiv:hep-ph/0604094v2 and subsequently validated in the thesis by René Ángeles Martínez.
Collaborator Contribution Simon Plätzer developed the original CVolver codebase to make progress in the difficult task of calculating the full colour evolution of QCD processes. This was achieved by calculating an approximation to the exponentiation of the so-called anomalous dimension matrix (in paper arXiv:1312.2448v1).
Impact Whilst the paper outlining this algorithm and providing an analytic description of the important way in which the code handles so-called colour has recently been submitted for publishing, we are still working (but close) to produce results to compare with community results.

Results and Impact "The Annual Theory Meetings ("Christmas Meetings") started in 1961 and have been held every year since (with the possible exception of two years), previously at the Rutherford Appleton Laboratory and more recently at Durham.". This meeting is for researchers in Theoretical Particle Physics to come together and present the latest advances in the field to the scientific community.

Results and Impact I presented the latest results of our Parton showevee, CVolver, at the QCD@LHC conference in Dresden. I explained the mechanics of the code in the context of the theoretical framework we have developed and presented our initial results relative to state-of-the-art Parton showers.
