Quark Confinement
"Quark Confinement 2023" is a Simons Foundation Collaboration and will be held May 2-6, 2023.
The workshop will focus on recent developments in our understanding of color confinement and QCD strings from a wide variety of perspectives, ranging from field theory to string theory, including both analytic and numerical techniques. The workshop is planned as in-person event. We plan to have about 40 active participants, but the number of talks per day will be kept limited so that there
is plenty of time for informal interaction and collaboration.

Workshop Location:
The workshop will be held in Keller Hall 3-180 on the East Bank of the University of Minnesota Twin Cities campus.
The building can be accessed via the main doors on Washington Avenue and the side doors on Union Street and the Scholars Walk.
Banquet Location:
The banquet for workshop participants will be held on Thursday, May 4th at 6:00 pm in University Hall at the McNamara Alumni Center.
Getting to the University of Minnesota:
Once you land at the Minneapolis/St. Paul International Airport (MSP), you have several options you can take to get to the University of Minnesota (UMN).
The Metro Transit Light Rail is the most efficient and cost effective mode of travel. It will cost $2.00 or $2.50 (rush hours) for a one-way ticket. The trains run every 10 - 15 minutes on weekdays and will get you to the UMN campus in about 30 minutes. From MSP, take the Blue Line north to US Bank Station. From there you will transfer to the Green Line and take that east to East Bank Station or Stadium Village Station. Find more information on the Light Rail Transit page of the MSP website.
Shuttle service is available from MSP, however the waits can be long and cost may be high at $20.00 - $73.00 depending on whether you share the ride or travel alone. To learn more see the Van and Shuttle service page of the MSP website.
Taxi services are available at MSP, including Uber and Lyft. It will take approximately 30 - 60 minutes to get to campus depending on traffic and will cost between $25.00 - $60.00. Visit the Ground Transportation page of the MSP website for more information on app-based ride services.
Car rental is not recommended. Parking around campus is limited and can be expensive.
Local Restaurants:
Please see our Restaurant Locations Map for ideas on where to eat in the area.
Lodging for non-local invited speakers will be provided by the workshop sponsors at the Graduate Minneapolis (room and tax only). The hotel is within blocks of the workshop venue and about 30 minutes from the MSP airport. Light-rail transit, Taxi or SuperShuttle service is available for transportation to the hotel and/or workshop location.
Information regarding details of hotel arrangements will be sent via e-mail to each participant of the workshop after registration. Please DO NOT contact the hotel to update reservations; contact the email address below for any changes that need to be made.
Please don't hesitate to contact us with any questions by e-mail at FTPI@umn.edu.
