Implications of LHCb measurements and future prospects

17 Oct 2018, 08:30 → 19 Oct 2018, 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), Vincenzo Vagnoni (Universita e INFN, Bologna (IT))

This is the 2018 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, and 8-10 Nov. 2017.

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 [Keri Vos, Michael Alexander, Jeremy Dalseno, Sevda Esen, email all]
• Semileptonic decays, rare decays, and tests of lepton flavour universality [Oliver Witzel, Mirco Dorigo, Preema Pais, email all]
• Electroweak physics, heavy flavour production, implications for (n)PDFs, heavy ions, and exotica searches [Lucian Harland-Lang, Albert Bursche, Carlos Vazquez, email all]
• QCD spectroscopy and exotic hadrons [Timothy Burns, Nicole Skidmore, email all]

The workshop will start on the morning of Wednesday 17 October at 08:30 and end on Friday 19 October at lunchtime.

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. As of 15 October, registration is closed; if you still wish to register and are not an LHCb member, please contact the LHCb Secretariat by email.

Please note that access to the CERN site is now restricted; this has changed since last year. 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.)

The organising committee are: Alex Lenz, Chris Parkes, Danny van Dyk, Giovanni Passaleva, Guy Wilkinson, Johannes Albrecht, Jure Zupan, Mat Charles, Monica Pepe-Altarelli, Svjetlana Fajfer, Vincenzo Vagnoni.

For general questions, please contact Mat Charles & Johannes Albrecht

Participants may also be interested in the Workshop on high-energy implications of flavor anomalies, organised by the CERN TH department and running from Oct 22 to Oct 24.
