Subject: [Sg-l:9905] 2nd Hokkaido Workshop on Particle Physics at Crossroads (March 3-6, 2026)
From: Ryuichiro Kitano (Sg-l 経由) 

Dear all,

We are pleased to announce the Particle Phenomenology Workshop, which 
will be held in Sapporo from March 3 to 6, 2026. A limited number of 
slots are available for contributed talks.

If you are interested in participating, please register through the 
Indico page:
https://conference-indico.kek.jp/event/346/

Registration will close once the maximum number of participants (~50) is 
reached. Please see below for a detailed description of the workshop.

Best regards,
Ryuichiro Kitano
on behalf of the Organizing Committee

Particle physics is at crossroads: the Standard Model is confirmed with 
unprecedented precision after decades of experimental explorations, and 
yet it offers no explanation to some of the most profound scientific 
puzzles such as the nature of dark matter and dark energy. Moreover, 
past theoretical guiding principles such as naturalness have not bore 
fruit in experimental searches. Quo vadis particle physics?

Pondering on the future, we would like to gather a small group of 
theoretical and experimental experts in an informal setting to evaluate 
the current state of affairs and devise future strategies, all 
surrounded by the natural beauty of Hokkaido in the winter.

This is the 2nd workshop of this series.
(last one in 2024: https://conference-indico.kek.jp/event/248/)

In this workshop, we plan to devote a significant amount of effort to 
the muon as a common thread between a very high energy collider and 
other low energy precision tests of the Standard Model, as well as their 
possible synergies. Wider theoretical/experimental topics on BSM 
(searches) will also be covered.
