Description

This is the 2017 edition of a series of workshops between the LHCb collaboration and the theory community. It follows similar meetings held on 10-11 Nov. 2011, 16-18 April 2012 (which resulted in a paper published in EPJ C 73 (2013) 2373), 14-16 Oct. 2013, 15-17 Oct. 2014, 3-5 Nov. 2015 and 12-14 Oct. 2016.

The purpose of the meeting is to consider the latest results from LHCb, discuss possible interpretations and identify important channels and observables to test leading theoretical frameworks in the near future of LHCb data-taking.

The meeting will be arranged in four streams, with three conveners each.

Mixing and CP violation in Beauty and Charm [Stefan Schacht, Alex Pearce, Wenbin Qian, email all]
Semileptonic decays, rare decays, and tests of lepton flavour universality [Danny van Dyk, Marianna Fontana, Stefanie Reichert, email all]
Electroweak physics, heavy flavour production, implications for (n)PDFs, and exotica searches [Rhorry Gauld, Martino Borsato, Emilie Maurice, email all]
QCD spectroscopy and exotic hadrons [Graham Moir, Jibo He, Ivan Polyakov, email all]

All interested theorists are welcome to participate, and are encouraged to register at the workshop INDICO page (there is no registration fee). To express interest in giving a presentation, please contact the conveners (once defined) of the relevant stream. Unfortunately, to allow informal discussion, we must restrict the participation to exclude members of competing experiments.

The workshop will start on Wednesday 8/11 at 8h30 and end on Friday 10/11 lunchtime.

Participants should arrange their own accommodation (e.g. at the CERN hostel). For administrative matters (e.g. concerning external access to CERN), please contact the LHCb Secretariat. If while booking a room at the CERN hostel you are required to specify a reference email address at CERN, please use LHCb.Secretariat@cern.ch

Organising committee: Fulvia De Fazio, Tim Gershon, Patrick Koppenburg, Alexander Lenz, Chris Parkes, Giovanni Passaleva, Marie-Helene Schune, David Straub, Vincenzo Vagnoni (chair), e-mail all
