Implications of LHCb measurements and future prospects

16 Oct 2019, 08:30 → 18 Oct 2019, 14:30 Europe/Zurich

500/1-001 - Main Auditorium (CERN)

Alexander Lenz (IPPP, Durham), Chris Parkes (University of Manchester (GB)), Danny van Dyk (TU München), Giovanni Passaleva (INFN Florence (IT)), Guy Wilkinson (University of Oxford (GB)), Johannes Albrecht (Technische Universitaet Dortmund (DE)), Jure Zupan (University of Cincinnati), Matthew John Charles (LPNHE Paris, CNRS/IN2P3 UPMC and UPD), Monica Pepe-Altarelli (CERN), S Fajfer (Univ. of Ljubljana and Inst. J. Stefan), Yasmine Sara Amhis (Centre National de la Recherche Scientifique (FR))

This is the 2019 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, 12-14 Oct. 2016, 8-10 Nov. 2017, and 17-19 Oct 2018.

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 the following conveners:

• Mixing and CP violation in Beauty and Charm [Matthew Kirk, Fabio Ferrari, Jinlin Fu, Nathan Jurik, email all]
• Semileptonic decays, rare decays, and tests of lepton flavour universality [Marzia Bordone, Peter Stangl, Carla Marin Benito, Ricardo Vazquez Gomez, email all]
• Electroweak physics, heavy flavour production, implications for (n)PDFs, heavy ions, and exotica searches [Fady Bishara, Charlotte van Hulse, Shanzhen Chen, email all]
• QCD spectroscopy and exotic hadrons [Feng-Kun Guo, Patricia Magalhaes, Biplab Dey, Tim Evans, email all]

The workshop will start on the morning of Wednesday 16 October and end on Friday 18 October around lunchtime.

All interested theorists are welcome to participate, and are encouraged to register at the workshop INDICO page.  To express interest in giving a presentation, please contact the conveners of the relevant stream (once defined; until then please contact Mat Charles and Johannes Albrecht).  Unfortunately, to allow informal discussion, we must restrict the participation to exclude members of competing experiments.

Please note that access to the CERN site is now restricted. If you are a CERN user with a CERN ID badge, you can enter with your badge as usual. Otherwise, you will require a visitor authorisation and special printable badge to enter. This authorisation will be handled by the LHCb Secretariat for all registered participants. Therefore, it's very important that visitors register in advance for the workshop. This is also related to accommodation at the CERN hostel, as explained below.

Participants should arrange their own accommodation. One option is the CERN hostel. To book at the CERN hostel:

• If you are a CERN user with an active CERN account, you can simply make a web booking.
• Otherwise, you will need to make a booking request (which can be done via this form). In nearly all cases, you should choose the "External CONF" status and the reason to visit CERN should be given as "Workshop/Seminar/Conference". The form will ask for a "CERN guarantor", for which you should specify one of the members of the LHCb Secretariat (Amelie Caillet, Nathalie Grüb, Cindy Denis) whose address is: LHCb.Secretariat@cern.ch . They have access to the list of registered participants and can confirm your participation. Please keep the Secretariat in cc for all email correspondance about your hostel booking.

For further help with these or other administrative matters, please contact the LHCb Secretariat. (If the CERN hostel becomes full, you may wish to try a third-party service such as Booking.com ; please note that CERN and the LHCb Secretariat will not be able to assist you with this.)

For those unable to attend in person, it will also be possible to connect to the conference remotely via Vidyo software. Please note that the main focus of the workshop remains on-site; we offer a video connection on a best-effort basis but cannot guarantee the quality or reliability of the connection. We do not accept remote talks, and those connected remotely will not be able to take part in the Q&A/discussion.

For general questions, please contact Mat Charles & Johannes Albrecht

As well as this webpage, occasional bulletins about the workshop series are available by email. If you wish to be added to the distribution list, please contact us. (Alternatively, those with CERN accounts should be able to add themselves to the e-group directly here.)
