The study investigates quark-sector Lorentz violation in Drell-Yan dilepton production with Z-boson exchange, demonstrating how the chiral nature of weak interactions allows for the study of parity-violating and spin-dependent effects using unpolarized initial states. Constraints on Lorentz violation coefficients for the first two generations of quarks are established based on measurements from the Large Hadron Collider.
Quark-sector Lorentz violation is studied in the context of Drell-Yan dilepton production including effects from Z-boson exchange. We show the chiral nature of the weak interactions enables parity-violating and spin-dependent effects to be studied using unpolarized initial states. Constraints are placed on dimensionless and CPT-even coefficients for Lorentz violation for the first two generations of quarks using measurements from the Large Hadron Collider.
