Soft photon emission at the LHC and the LBK theorem — •Roger Balsach¹, Domenico Bonocore², and Anna Kulesza¹ — ¹Institute of Theoretical Physics, WWU Münster, D-48149 Münster, Germany — ²Physik Department T31, Technische Universität München, D-85748, Garching, Germany

The emission of low energetic (soft) photons plays a fundamental role in the understanding of Quantum Field Theories. However, there appears to be a discrepancy between the experimental measurements and the calculations for one-photon emission observables. Furthermore, future improvements to the ALICE detector will result in better measurement of soft photon emission, necessitating increasing precision of theoretical predictions.

For those reasons, we compute the cross-section for processes with a single photon emission including NLP and one-loop QCD corrections.
