Abstract
We present a calculation of interference effects in Hjj production via gluon fusion and via vector boson fusion, respectively, beyond tree level. We reproduce results recently discussed in the literature, but go beyond this calculation by including a class of diagrams not considered previously. Special care is taken in developing a numerically stable and flexible parton level Monte-Carlo program which allows us to study cross sections and kinematic distributions within experimentally relevant selection cuts. Loop-induced interference contributions are found to exhibit kinematical distributions different in shape from vector boson fusion. Due to the small interference cross section and cancelation among different quark flavor contributions their impact on the signal process is found to be negligible in all regions of phase space, however.
