From March 16 to 19, 2020, the yearly workshop "Beyond the Standard Model" will take place at the Physikzentrum Bad Honnef, organized by Gleb Arutyunov (Hamburg). The workshop focuses on recent developments in the theory of fundamental particles, the physics of the early universe, and mathematical physics. There will be introductory pedagogical lectures as well as shorter talks by the participants.
For more information see the webpage.

The Bethe Center for Theoretical Physics in Bonn will host a Bethe Forum on "Inflation" from March 23rd to 27th. The organizers are Marco Peloso (Padua), Manuel Drees (Bonn, Hans Peter Nilles (Bonn) and Ivonne Zavala (Swansea).

The first Bethe Colloquium for the summer term 2020 is scheduled for Thursday, April 23rd, at 4:15 pm in Hörsaal I.

• Frank Close (University of Oxford)
• Trinity - The treachery and pursuit of the most dangerous spy in history
• Hörsaal I, Physikalisches Institut

Abstract: Trinity was the codename for the test explosion of the atomic bomb in New Mexico on 16 July 1945. Frank Close tells the story of the bomb's metaphorical father, Rudolf Peierls (who discovered the concept in 1940); his intellectual son, the atomic spy Klaus Fuchs who worked with him in Birmingham and Los Alamos; and the ghosts of the security services in Britain, the USA and the USSR. Frank will reveal new insights from MI5 files in the National Archives, and documents of the FBI and KGB. He has also overthrown a misconception lasting 60 years that J Edgar Hoover was central to Fuchs' exposure: the real hero was probably the British codebreakers at GCHQ. By using contacts outside the United Kingdom to access documents that remain classified there, he has also found evidence that Fuchs passed information about the Hydrogen bomb to the USSR as early as September 1945. For the first time, Fuchs' role on the top secret British Atomic bomb project from 1946 to his arrest in 1950 is examined, not least how Fuchs used this to cover his tracks when meeting his Soviet contact in London.

The Bethe Forum on "Modular Flavor Symmetries" is scheduled for May 4th to 8th, 2020, in the Bethe Center for Theoretical Physics in Bonn. The organizers are Michael Ratz (Irvine), Ferruccio Feruglio (Padua), Tatsuo Kobayashi (Sapporo) and Hans Peter Nilles (Bonn).
