The Flavour Anomaly and Implications Workshop is dedicated to the memory of Sheldon Stone.

 

This is the 2021 edition of a series of workshops between the LHCb collaboration and the theory community. 

• Registration:
  • The Implication Workshop takes place in the same week as the Flavour Anomaly Workshop
  • Please register for the Implications Workshop here: registration Registration will close Thu 14 Oct. Please contact <Lhcb.Secretariat@cern.ch> in case of problems.
  • Max. 72 people can be welcomed in the Main Auditorium.
    • No Sanitary pass is required
    • First-come-first-serve policy
• Previous Editions:
  • 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

• Goal of the meeting: 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.
• Participation: all interested theorists are welcome to participate, and are encouraged to register at the INDICO page of the Flavour Anomaly Workshop of 20 Oct.  To express interest in giving a presentation, please contact the conveners of the relevant stream (once defined; until then please contact Niels Tuning, and Marco Pappagallo).  Unfortunately, to allow informal discussion, we must restrict the participation to exclude members of competing experiments.
• COVID-19: This year's workshop will go ahead but, due to the COVID-19 situation, will take place in a hybrid mode. It will be possible to connect to and participate fully in the conference remotely via videoconference software (most likely Zoom).
• Other information
  • For further help with these or other administrative matters, please contact the LHCb Secretariat.
  • For general questions, please contact  Niels Tuning, and Marco Pappagallo
