This is the 2023 edition of a series of workshops between the LHCb collaboration and the theory community. 

• 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,
  • 8-10 Nov. 2017,
  • 17-19 Oct 2018, 
  • 16-18 Oct 2019,
  • 19-21 Oct 2020  
  • 19-22 Oct 2021 and 
  • 19-21 Oct 2022
• 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 workshop INDICO page.  To express interest in giving a presentation, please contact the conveners of the relevant stream.  Unfortunately, to allow informal discussion, we must restrict the participation to exclude members of competing experiments.
