Electromagnetic Radiation from Hot and Dense Hadronic Matter

26 Nov 2018, 08:00 → 30 Nov 2018, 18:00 Europe/Rome

Meeting room (ECT* - Villa Tambosi)

Gabor David - Stony Brook University (Stony Brook University), Charles Gale - McGill University (McGill University)

Electromagnetic Radiation from Hot and Dense Hadronic Matter

This workshop will bring together theorists and experimentalists working on direct photons and dileptons in (ultra)relativistic heavy ion collisions. Beyond the survey of the current status, a large emphasis will be given to open discussions on the new possibilities offered by the widening range of colliding systems and collision energies. Another important goal is to move toward more consistent analysis methods, to make data from different experiments easier to compare with each other, and with theory calculations.

Key Topics:

• Electromagnetic radiation from hot and dense strongly interacting matter 
• Status of our understanding of current experimental methods and results
•  The “photon flow puzzle”
• Progress in photon and dilepton production theory 
• Future experiments
