57. Quark-gluon plasma and the physics of light ion collisions at the Large Hadron Collider

Wilke van der Schee (UU/CERN)

07/11/2025, 10:30

n 2010 the Large Hadron Collider collided for the first time lead ions with a Lorentz gamma factor exceeding 1000. Such ultrarelativistic collisions create a quark-gluon plasma with an extremely high temperature. I will explain the basic physics of such collisions and then showcase very new results of similar collisions of oxygen and neon that were just performed last summer. Oxygen and neon...

56. Primordial non-Gaussianities: What are they, why do we care, and how do we measure them

Dr Daan Meerbrug (RUG)

In this talk, I will explain why primordial non-Gaussianities are considered to be one of the most exciting targets in cosmology, on par with primordial gravitational waves (and certainly more exciting than the Hubble tension!). Primordial non-Gaussianities cause the initial conditions to contain moments beyond the variance or power spectrum (second moment) and can be caused by a variety of...

37. Constraining the sources of ultra-high-energy cosmic rays with experimental measurements

Ultra-high-energy cosmic rays (UHECRs) are the most energetic particles known - and yet their origin is still an open question. However, leveraging the precision and accumulated statistics of the largest observatory in the world, the Pierre Auger Observatory, it is now possible to set constraints on the sources of UHECRs. The spectrum and mass composition measurements at the highest energies...

39. MYRRHA and its driver accelerator

Adrian Fabich

07/11/2025, 19:00

MYRRHA is the first Accelerator Driven System (ADS) to be built, consisting of a subcritical nuclear reactor driven by a high power linear accelerator, for the demonstration of transmutation of nuclear waste at pre-industrial scale. With the subcritical concentration of fission material, the nuclear reaction is sustained by the particle accelerator only.
The MYRRHA design for an ADS is based...
