Prague Spring Amplitudes Workshop

15 May 2023, 10:30 → 18 May 2023, 18:00 Europe/Zurich

Prague

Karol Kampf (Charles University (CZ)), Jaroslav Trnka, Adam Smetana (Czech Technical University in Prague (CZ))

Prague Spring Amplitudes Workshop focuses on some selected problems of scattering amplitudes and related topics. The schedule will allow plenty of time to discuss recent problems and challenges in the field.

Location

The workshop will take place May 15-18 in the heart of Prague in the building of the Institute of Experimental and Applied Physics of the Czech Technical University in Husova 5. It is located in the Old Town, close to all historical monuments, shops and restaurants.
