Description
This 3 days workshop aims at gathering string theorists and cosmologists to discuss recent developments on the timely topics of:
- Dark energy (cosmological constant or dynamical)
- Hubble tension and early dark energy models
- Inflation and CMB
- Cosmological correlators
considering both observational constraints (including DES, DESI results, prospects from Euclid, LSST, and CMB observations) as well as theoretical constraints (cosmological model building, string theory realisations and swampland obstructions). Ample time will be given for discussions between the participants and members of the two communities. Recent related events include the String - Cosmo Day and the AES3L workshop. This workshop takes part in the Transverse Task Force activities of the GdR CoPhy.
The workshop will take place in the Auditorium of LAPTh in Annecy, France, from the 10th till the 12th December 2025.

Public outreach talk: On Wednesday 10th December, there will be a public event from 17h until 19h, including at 18h a public outreach talk in French by Thibaut Coudarchet. This is part of "Les Mercredis du LAPP et du LAPTh".
Registration: is open from the 8th September till the 12th November (or earlier if filled). Registration is mandatory for participation. For organisational reasons, unfortunately, we cannot accept more than about 80 participants. Therefore, each registration will be subject to approval, and confirmation will be sent. Priority will be given to experts in the field.
Contributed talks: we offer the possibility to young participants to propose a contributed talk of 20 minutes, including questions. This is done together with the registration. This call will be open from the 08th September till the 03rd October 2025, after which we will proceed with a selection.
Coffee, 3 lunches and 1 workshop dinner: those will be offered to registered participants. Attendance is asked during registration. Coffee and lunches take place at LAPTh. The workshop dinner will take place on Thursday 11th December at 19:30 at the restaurant Bleu Imperial. To reach the dinner restaurant as a group, we will leave LAPTh and catch the Bus 1 at Campus (18:41 or 18:53), stop at Montremont and walk along Avenue de France.
Accommodation: we recommend Hotel de Bonlieu, Allobroges Park Hotel or Moxy Annecy, even though many other hotels are possible in Annecy. Speakers and discussion conveners get two nights (10-12th Dec.) pre-booked and covered by us.
Travel information: nearby airports are in Geneva and Lyon. Annecy can also be reached by train (SNCF) or by bus (see below).
From Geneva airport as well as Geneva Cornavin train station, you can reach Annecy by train or by bus (272). It takes between 1:30 to 2 hours, and booking for both can be done on the Swiss train website. A faster option (45 mins), although traffic and border dependent, is by car. Other options are Flixbus (bus) or Blablacar (bus and car sharing).
From Lyon airport, you would have to take a fast tram to Lyon La Part Dieu train station. From there, you can take a train to Annecy (between 1:30 to 2 hours). Other options from Lyon are by car (1:30 hour) or again Flixbus or Blablacar.
Once at Annecy train and bus station, or from the city center, LAPTh can easily be reached by bus (e.g. with line 1, direction "Parc des Glaisins", stop at "Campus") following these instructions. It takes about 20 mins, and tickets can be bought with cash at the bus driver, or with a text message (SMS). SIBRA is the public transport website.
More travel information can also be found here. Travel expenses remain to be covered by participants.
Social activities: Annecy, with its lake and old city, deserves to be explored. At this time of the year, we also recommend the Christmas markets. In addition, the mountain surroundings offer ski resorts, sometimes reachable by public transport.
Disclaimer: Some registered participants have been contacted via phishing emails about their "hotel booking" or "reservation confirmation". Please be careful, this is a scam.
