Search for Contact Interactions in e^{\pm}p Collisions at HERA

Understand

A search for physics beyond the Standard Model in neutral current deep inelastic scattering at high negative four-momentum transfer squared Q^2 is performed in e^{\pm}p collisions at HERA.

• The differential cross section ds/dQ^2, measured using the full H1 data sample corresponding to an integrated luminosity of 446 pb^{-1}, is compared to the Standard Model prediction.
• No significant deviation is observed.
• Limits on various models predicting new phenomena at high Q^2 are derived.
