Nucleon Structure Laboratory (LSN) – The internal structure of hadrons

The Nucleon Structure Laboratory leads research programs in hadron physics and Quantum Chromodynamics (QCD) with a specific focus on the internal structure of hadrons. Its activities can be classified into three major branches:

  • Experimental nuclear physics: propose, conceive, build and run new experiments, perform data acquisition and analysis,  apply statistical methods for physics analysis , and also prospect for future experimental facilities (Electron-Ion Collider : EIC).
  • Theoretical nuclear physics: modelling the hadron structure, ab initio computations, study of polarization effects in lepton or hadron scattering, theoretical analysis of experimental data, phenomenology of hadron structure functions.
  • Detector physics: research and development of innovative detectors, including potential applications beyond nuclear and particle physics.

The research programs of the Nucleon Structure Laboratory cover in a consistent way all the modern aspects of nucleon structure, from the theoretical motivation of some key problems to the design of the required associated detectors.

  • sPHENIX

    sPHENIX

    sPHENIX is a new detector that will be installed at RHIC, BNL. sPHENIX will feature the most advanced technologies for studying strongly coupled quark-gluon plasma using jets and heavy flavors as observables. The goal of sPHENIX is to understand the microscopic structure of plasma and reveal how its strongly coupled nature emerges from the elementary…
