Complete O(α) QED corrections to the process ep → eX in mixed variables
نویسندگان
چکیده
The complete set of O(α) QED corrections with soft photon exponentiation to the process ep → eX in mixed variables (y = yh, Q 2 = Ql ) is calculated in the quark parton model, including the lepton-quark interference and the quarkonic corrections which were unknown so far. The interference corrections amount to few percent or less and become negligible at small x. The leading logarithmic terms proportional to ln(Q/mq) from radiation off quarks are discussed and the non-logarithmic quarkonic corrections found to be negligible for almost all experimentally accessible x and y.

LEPTONIC QED CORRECTIONS TO THE PROCESS ep − → eX IN JAQUET - BLONDEL VARIABLES
For the study of deep inelastic scattering at HERA, the use of Jaquet-Blondel variables is advantageous in several respects. We calculate the complete leptonic O(α) QED corrections for the reaction ep → eX in these variables. All but one phase space integrations are performed analytically. After exponentiation of soft photon corrections, an accuracy of at least 1% is matched. Numerical results ...

متن کاملModel independent QED corrections to the process ep − → eX †
We give an exhaustive presentation of the semi-analytical approach to the model independent leptonic QED corrections to deep inelastic neutral current lepton-nucleon scattering. These corrections include photonic bremsstrahlung from and vertex corrections to the lepton current of the order O(α) with soft photon exponentiation. A common treatment of these radiative corrections in several variabl...

Deep inelastic scattering provides us with detailed information on the nucleon structure. In order to extract the parton distribution functions from DIS cross sections and to measure αs(M 2 Z) with high precision it is crucial to control the QED radiative corrections. The 1– and 2–loop leading–log QED corrections were derived in Ref. [1–3]. Complete 1-loop corrections for DIS were given in Refs...
متن کاملO(αL) Radiative Corrections to Deep Inelastic ep Scattering
The leptonic QED radiative corrections are calculated in the next-to-leading log approximation O [ α2 ln(Q/me) ] for unpolarized deeply inelastic ep–scattering in the case of mixed variables. The corrections are determined using mass factorization in the OMS– scheme for the double–differential scattering cross sections.
