Limits on the effective quark radius from inclusive $ep$ scattering at HERA
Abstract
The high-precision HERA data allows searches up to TeV scales for Beyond the Standard Model contributions to electron-quark scattering. Combined measurements of the inclusive deep inelastic cross sections in neutral and charged current scattering corresponding to a luminosity of around 1 fb have been used in this analysis. A new approach to the beyond the Standard Model analysis of the inclusive data is presented; simultaneous fits of parton distribution functions together with contributions of "new physics" processes were performed. Results are presented considering a finite radius of quarks within the quark form-factor model. The resulting 95% C.L. upper limit on the effective quark radius is cm.
