Description

The H1 and ZEUS experiments at HERA have recently presented the combined measurement of inclusive deep inelastic cross sections in neutral and charged current ep scattering corresponding to a luminosity of about 1 fb-1. The high precision of the data makes searches for new contributions to electron-quark scattering possible up to TeV scales. A new approach to beyond the Standard Model (BSM) analysis of inclusive ep data is outlined, taking into account possible contributions to the QCD fit of parton distributions coming from ''new physics'' processes. Results are presented considering a finite radius of quarks within the quark form factor model. The resulting 95% C.L. upper limit for the radius of the electroweak charge of quarks is 0.43 . 10-16 cm.
