Dear Colleagues,

We would like to cordially invite you for the XXVI International Workshop on Weak Interactions and Neutrinos (WIN 2017) at the University of California, Irvine in the sunny Southern California (south of Los Angeles). The scientific program will take place from June 19th through June 24th of 2017.

The International Workshops on Weak Interactions and Neutrinos have been organized regularly for the past 40 years at venues in Africa, Asia, Europe and the United States, with the last Workshop taking place in Heidelberg, Germany in June 2015. These Workshops offer the physics community a significant opportunity to assess the status of major topics within the field and initiate collaborative effort to address current challenges. The Workshops attract leading experimentalists and theorists, from all over the world, who take advantage of the occasion to work with colleagues on common problems. In many cases the efforts initiated at these Workshops result in completed projects that are published in international journals. These projects have sometimes proven to be major breakthroughs such as the MSW effect, which was first discussed at the WIN85 meeting in Finland.

As customary in this workshop series, the program will be structured to allow ample time for formal and informal discussions in the four working groups:

– Neutrino Physics
– Weak Interactions
– Flavor Physics
– Astroparticle Physics

Registration and abstract submission will be open by early February 2017.

We look forward to seeing you in Irvine in the summer!
