Trieste, 16-18 November and 19-20 November 2020

15 Nov 2020, 18:00 → 20 Nov 2020, 19:00 Europe/Rome

IWHSS 2020 is the 17th in a series of  International Workshops on Hadron Structure and Spectroscopy which the COMPASS  Collaboration  holds every year to review the status of the physics  topics  under  investigation  and to discuss future activities.

The focus of the Workshop will be on

• Spectroscopy
• Spin and 3D Structure of the Nucleon from SIDIS and Drell-Yan processes
• Fragmentation Functions
• Generalized Parton Distributions from DVCS and hard exclusive meson production
• New experimental techniques

Special sessions will be devoted to "The emergence of hadronic mass" and to "The proton radius puzzle".

 

IWHSS 2020, originally scheduled in May 2020 in Trieste, will take place from 16 to 18 November 2020. The recent evolution of the COVID-19 emergency, and the restrictions decided by the Italian government on 25 October, have ruled out the possibility to have a "hybrid" workshop, and only remote participation will be possible. Details will be given in "Participation".

Registration closed on 20 October.

 

The Workshop will be followed by the COMPASS Collaboration Meeting, on 19 and 20 November.

 

Organized by INFN, Division of Trieste, in collaboration with the Physics Department of the University of Trieste, in the context of the proESOF initiative and ESOF2020 satellite events
