Parton Showers, Event Generators and Resummation 2017

27 Mar 2017, 08:00 → 29 Mar 2017, 18:00 Europe/London

The Queen’s Building (Emmanuel College, Cambridge)

With the large statistics rapidly accumulating at the LHC, the need for reliable event generators and predictions that go beyond fixed-order perturbation theory becomes ever more pressing.  The aim of the PSR workshop is to achieve advances in this direction by bringing together the QCD communities involved in analytic resummations and parton shower event generators. In particular, it will cover the following topics:

• Different resummation techniques and their relations
• Different parton-shower formalisms and their relations
• The connection between parton showers and resummation
• Matching of showers and resummations with fixed-order results

The workshop will continue the successful series of meetings at DESY Hamburg (2009, 2012), Manchester (2010), Durham (2013), Munster (2014), Krakow (2015) and Paris (2016).
