Full next-to-leading-order electroweak corrections were calculated for off-shell vector-boson scattering. These corrections significantly impact the fiducial cross section, revealing intrinsic features of these scattering processes.
Area of Science:
- High Energy Physics
- Quantum Field Theory
- Particle Physics
Background:
- Vector-boson scattering (VBS) processes are crucial for understanding electroweak symmetry breaking.
- Precise theoretical predictions are essential for interpreting experimental data at particle colliders.
Purpose of the Study:
- To present the first full next-to-leading-order electroweak corrections to off-shell vector-boson scattering.
- To investigate the impact of these corrections on the fiducial cross section.
Main Methods:
- Computation of complete matrix elements for the electroweak process pp→μ^{+}ν_{μ}e^{+}ν_{e}jj.
- Inclusion of all nonresonant and off-shell contributions.
- Fully differential calculation.
Main Results:
- Surprisingly large electroweak corrections of up to -16% for the fiducial cross section were found.
- These large corrections are an intrinsic feature of vector-boson-scattering processes.
- The origin of these corrections was elucidated using approximations.
Conclusions:
- Electroweak corrections play a significant role in off-shell vector-boson scattering.
- The findings provide a more precise theoretical framework for VBS studies.
- Further theoretical and experimental investigations into VBS are warranted.
