Multi-Boson Interactions 2021

Aug 23, 2021, 1:50 PM → Aug 27, 2021, 1:00 PM Europe/Zurich

Warning: all conference participants are kindly required to fill in this form

The 2021 edition of the MBI International Conference is jointly organised with the VBSCan COST Action in the Milano - Bicocca University, with the support of the INFN.

The program will cover the latest experimental results, the state-of-the art theory calculations and future prospects of the physics with multi-boson final states at particle colliders, and will be the closing event of the VBSCan COST Action.

The conference will be hybrid to allow for a wide participation, and its format will be finalised in early summer, as a function of the international situation of the covid pandemics control.

The conference will take place in the Building U6-Agorà (google maps link).

Please remember that a valid COVID-19 Green Pass will be mandatory to enter the conference hall.
