Massive c(\bar c)g-Production in Diffractive DIS
J. Bartels, H. Jung, A. Kyrieleis
We calculate the cross section for q(\bar q)g-production in diffractive DIS with finite fermion masses and zero momentum transfer. The calculation is done in the leading log(1/x_p)…

Factorization of Twist-Four Gluon Operator Contributions
Jochen Bartels, Claas Bontus, Hubert Spiesberger
We consider diagrams with up to four t-channel gluons in order to specify gluonic twist-four contributions to deep inelastic structure functions. This enables us to extend the meth…
