Abstract: In high-energy physics, electroweak bosons can undergo vacuum fluctuations into quark-antiquark pairs, which interact strongly with hadrons. This process plays a crucial role in describing the parton distribution inside the proton, providing key insights into hadron structure and properties.
In this seminar, we explore how the proton’s internal structure is probed by W bosons using both unpolarized and polarized beams, revealing parity violation effects and contributing to the understanding of the proton spin puzzle. Our approach is based on the dipole formalism, incorporating nonlinear small-x evolution equations.
Additionally, we investigate the vacuum structure through boson-boson interactions, where both bosons fluctuate into quark-antiquark pairs, effectively modeling like hadron-boson interactions. This framework allows us to extract the QCD vacuum structure and study parity violation effects, with energy dependence at increasing scales.
