Femtoscopy studies using the "Correlation Analysis Tool using the Schrödinger equation" (CATS) — •Dimitar Mihaylov and Laura Fabbietti — James-Franck-Straße 1, 85748 Garching, Germany

The femtoscopy method can be used to investigate both the emission source and the interaction potential between particle pairs by measuring their correlation function. Recent studies have demonstrated that femtoscopy can be deployed to study the hyperon-nucleon interaction at low relative distances and momenta. The deeper understanding of those interactions is relevant not only in nuclear physics, but is strongly linked to the equation of state which in turn relates to the structure of neutron stars.

Femtoscopy analyses performed in high energy pp collisions at ALICE demonstrated bigger sensitivity to the interaction potentials due to the small emission source. However the currently available analysis tool in the field tend to be approximate and only applicable to larger source radii. This motivated us to develop the “Correlation Analysis Tool using the Schrödinger equation” (CATS) which entirely relies on numerical methods to evaluate the correlation function.

In this talk we will explain the basic working principles of the new tool, we will test it against established benchmark methods in the field and finally we will present the results from the first physics studies performed with CATS.
