Sum rule improved double parton distributions in position space

11 May 2020  ·  Diehl Markus, Gaunt Jonathan R., Lang Daniel M., Ploessl Peter, Schafer Andreas ·

Models for double parton distributions that are realistic and consistent with theoretical constraints are crucial for a reliable description of double parton scattering. We show how an ansatz that has the correct behaviour in the limit of small transverse distance between the partons can be improved step by step, such as to fulfil the sum rules for double parton distributions with an accuracy around 10%...
