The CLASH project is a collaboration between experimental and theoretical particle physicists at Lund University, Sweden. It is headed by Peter Christiansen and Leif Lönnblad and funded by the Knut and Alice Wallenberg Foundation.
The project focuses on improving the understanding of some of the most debated experimental results from the Large Hadron Collider (LHC) at CERN. The main goal of the project is to directly confront the traditional paradigm for small collision systems (microscopic models based on quarks and gluons) with the QGP-paradigm originating in large collisional systems (macroscopic models based on relativistic viscous hydrodynamics) and to identify the most sensitive observables for differentiating between the model descriptions.
