Beyond the Flavour Anomalies V

9 Apr 2024, 08:30 → 11 Apr 2024, 18:45 Europe/Berlin

Aula (Kulturhaus Lÿz, Siegen)

Aleksey Rusov (University of Siegen)

The 5th edition of the "Beyond the Flavour Anomalies" workshop will take place in Siegen, Germany, from 9th April till 11th April 2024. It will be hosted by the theoretical particle physics group of the University of Siegen.  

The previous editions of the "Beyond the Flavour Anomalies" workshop are:

1. Online, 1-3 April 2020 
   https://conference.ippp.dur.ac.uk/event/876/
2. Online, 20-22 April 2021
   https://conference.ippp.dur.ac.uk/event/944/
3. IPPP, Durham University, 26-28 April 2022
   https://conference.ippp.dur.ac.uk/event/1064/
4. Barcelona, 19-21 April 2023
   https://conference.ippp.dur.ac.uk/event/1175/

The purpose of this event, organized shortly after the Moriond conference in March, is to bring together world-leading experts from theory and experiment to discuss in detail the current status of anomalies in flavour physics. The format of the workshop includes several talks, covering experimental overviews and prospects of measurements of flavour observables, and the theory status of these anomalies, including both the SM side (by revisiting the underlying hadronic effects) and possible BSM scenarios. Joint discussions between experimentalists and theoreticians of different aspects of the anomalies in an informal way will definitely be helpful to shed more light on origins of these tensions as well as to shape a clearer path for future studies and investigations. 

Preliminary topics of the workshop are:

• Rare semileptonic decays
• Tree-level semileptonic decays
• Lepton flavour universality ratios
• Tree-level non-leptonic decays
• Charm sector
• Hadronic effects
• Experimental overviews and prospects
• Beyond the Standard Model 

In order to encourage more informal, fruitful and insightful discussions, the number of participants is limited. Therefore participation is by invitation only.

Organising Committee

• Alexander Lenz (Siegen University)
• Mitesh Patel (Imperial College London)
• Konstantinos Petridis (Bristol University)
• Aleksey Rusov (Siegen University)
• Danny van Dyk (Durham University) 

Secretariat

Important message:

Already several participants received a scam email, offering to arrange for their accommodation in Siegen during the workshop. We would like to stress, that we have NOT arranged such a service and do NOT pass on information provided in the registration form. So do NOT respond to these offers! 

We stress that all the participants need to arrange for their accommodation themselves, either by contacting the hotels directly (some suggestions are given at the section "Accommodation suggestions") or using reputable hotel-booking sites.
