Anomalous WW-gamma Vertex at LC+HERA Based gamma-p Collider

TL;DR

This paper explores the potential of a combined LC+HERA gamma-p collider to detect anomalous WW-gamma couplings, demonstrating competitive sensitivity and providing limits comparable to future collider projections.

Contribution

It introduces the sensitivity analysis of the LC+HERA gamma-p collider for anomalous WW-gamma couplings and compares its effectiveness with other collider methods.

Findings

Limits of -0.16<(kappa-1)<0.14 and -0.30<lambda<0.30 at 95% C.L. are achievable.

The collider's sensitivity is competitive with future collider projections.

Results are compared with ep collider predictions using Weizsacker-Williams Approximation.

Abstract

The potential of LC+HERA based gamma-p collider to probe WW-gamma vertex is presented through the discussion of sensitivity to anomalous couplings and p_{T} distribution of the final quark. The limits of -0.16<(kappa-1)<0.14, -0.30<lambda<0.30, at 95% C.L. can be reached with integrated luminosity 100pb^{-1} and they are competitive to projected future limits from other colliders. The results are compared with corresponding ep collider using Weizsacker-Williams Approximation.
