About me:
I am Fernando Romero-López, originally from Valencia, Spain. I completed my PhD in 2021 at the University of Valencia and I have been a postdoc at the Massachusetts Institute of Technology since then. My research focuses on understanding hadronic interactions and nuclear properties using a combination of lattice QCD and effective field theories. I study multi-hadron systems and hadronic resonances, and how their properties can be extracted from lattice QCD simulations. I am also working on machine learning research for lattice field theory, specifically utilizing flow models for accelerating the generation of gauge field configurations.
Seminar Title:
Hadronic resonances from lattice QCD
Seminar Date:
May 16th, 2023
Abstract:
The majority of known hadrons in the low-energy QCD spectrum are resonances observed in multi-particle scattering processes. First-principles determinations of the properties of these unstable hadrons are a crucial goal in lattice QCD calculations. Significant progress has been made in developing, implementing, and applying theoretical tools that connect finite-volume lattice QCD quantities to scattering amplitudes, enabling determination of masses and widths of various hadronic resonances. In this talk, I will discuss recent advances in the study of meson-baryon resonances, including the Delta(1232) and Lambda(1405) resonances, as well as three-body processes using lattice QCD.
