We present an analysis to extract kaon parton distribution functions (PDFs) using meson-induced Drell-Yan and quarkonium production data. Starting from the statistical model, first developed for describing the partonic structure of nucleons and later applied to the pion, we have extended this approach to perform a global fit to existing kaon-induced Drell-Yan and charmonium production data....
The proton charge radius is one of the pivotal quantities in physics. In particular, its value is highly correlated with the experimental determination of the Rydberg constant. For the past seventy years it has been measured through elastic electron-proton scattering and ordinary hydrogen spectroscopy methods. Over the years, results from both methods generally agreed with each other within...
In this talk, I will highlight recent semi-inclusive deep inelastic scattering (SIDIS) studies carried out at Jefferson lab to probe hadronization mechanisms and associated medium modifications of the underlying structure of atomic nuclei, with a focus on the first-ever SIDIS Lambda production in the current and target fragmentation regions. These new results, alongside the lately collected...
The initial scientific case for upgrading the Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Lab (JLab) to 22 GeV will be presented. The proposed physics program encompasses a large and diverse range of transforamtive investigations centered around the non-perturbative dynamics inherent in hadron structure and the exploration of strongly interacting systems. It builds upon...
The goal of LHCspin is to develop innovative solutions and cutting-edge technologies to advance the field of spin physics over the next few years, by exploring a unique kinematic regime and exploiting new reaction processes. To achieve this, a polarized gaseous target, operated in combination with high-energy, high-intensity LHC beams and the highly performing LHCb particle detector, has the...
Many of the physicists working in this field were not alive in 1974 and many others have not heard of the November Revolution. We give that name to an event at the SLAC Auditorium on November 11, 1974 when teams from Brookhaven and SLAC announced the remarkable results that heralded the discovery of the fourth quark, charm. This discovery led, very quickly, to the Standard Model of Particle Physics.
