Abstract:
The femtoscopy technique at the Large Hadron Collider has proven capable of providingunprecedented precision information on the low-energy interaction between nucleons andstrange hadrons. The experimental methodology exploits the emission of particle pairs atthe femtometer scale in the collisions and analyzes the momentum correlation induced byfiee scattering of the produced hadrons. The measurements of the p-A and p-E.correlation functions by the ALICE collaboration have been used to challenge effectivefield theory results and to test for the first time lattice OCD calculations, Recently, thesame experimental technique has been used to access the dynamics of three hadrons andthree-nucleon (N-N-N)as well as N-N-A correlation measurements became availablePhenomenological calculations indicate that the effect of the three-body forces in the NN-A correlation function is pronounced, demonstrating that correlation function analysescan be used to access the dynamics of few-body systems. In this seminar, I will discussthe impact of the femtoscopy method on the understanding of the two-and three-bodyinteractions with hadrons.

About the speaker:
Raffaele Del Grande earned B.S. from U ofL'Aquila (2011),M.S. from U of Rome La Sapienza (2014),and Ph.D. fromINFN Frascati (2018), studying hadronic physics at DAFNE.As a postdoc in Frascati (2018-2020), he researched kaonicatoms at DAFNE and Pauli-violating atoms at Gran SassoLab. In 2020, he joined ALICE group of Tech. U in Munichfocusing on hadronic interaction studies via femtoscopy andcoordinating all ALICE femtoscopy analyses (2022-2024)In 2025, he became Asst. Prof. at Czech Tech. U in Prague.
