Abstract
We investigate the Lorentz-violating effects of Standard Model Extension (SME) in single W boson production process pp → pγp → p W- q' X at the Large Hadron Collider (LHC). We employ the Weizsacker-Williams approximation for photons emitted from one of the incoming proton beams and consider γq → W- q' as a subprocess in the proton-proton collision. The behavior of the differential cross-section for various orientations of the constant background fields is obtained by taking into account longitudinal and transverse polarization states of the final W bosons.
Highlights
The Standard Model (SM) of particle physics and Einstein’s general theory of relativity are the most successful theories to date
Lorentz symmetry is involved as a fundamental assumption in both of these theories and the unification of these theories is expected to make an agreement at Planck scale, mp ≃ 1019 GeV, for a unified quantum description of nature
The Planck scale is 1015 times larger than the energy achieved at the Large Hadron Collider (LHC)
Summary
The Standard Model (SM) of particle physics and Einstein’s general theory of relativity are the most successful theories to date. We are interested in the subprocess γq → W −q′ in photon-proton collisions at the Large Hadron Collider (LHC) in the presence of a constant antisymmetric tensor background field b θφ .
