Precision studies of the strongly interacting NΛ–NΣ coupled system at the LHC — •Dimitar Mihaylov — TUM, Physics Department, James-Franck-Straße, 85748 Garching

The study of the strong interaction among stable and unstable hadrons is a fundamental question in nuclear physics and it is a key ingredient for the description of the Equation of State, and the understanding of the structure of dense stellar objects, such as neutron stars. Traditional measurements, including scattering and hypernuclei experiments, are insufficient to provide strong constraints to the theoretical modeling of the interaction between hadrons containing strangeness.

Two particle correlation measurements are a prominent tool to probe the strong interaction with high precision even in the multi-strangeness sector. The ALICE collaboration has demonstrated that high-multiplicity pp collisions are particularly well suited due to the enhanced production of strangeness. Combined with the excellent tracking and particle identification capabilities of the ALICE detector, precision studies of the strong interaction among strange hadrons is possible. The present contribution will discuss the latest ALICE results on the study of the NΛ–NΣ coupled system through measurement of the pΛ correlation function.
