Presenting the first set of LL corrections to sub-leading processes within W+Jets in HEJ. This adds resummation to many processes previously only matched to FO.
Double parton scattering is usually suppressed by single parton scattering. However, in some specific regions of phase-space, the differential cross-sections are comparable. Also, for a given final state, it might happen that the double parton scattering is the dominant contribution if the single parton scattering is suppressed by a higher multiplicity of couplings. For these reasons, it turns...
Most parton showers currently work in the leading colour limit, allowing for coherent gluonic radiation through either angular ordering or the dipole/antenna formalist. For photon emission, the equivalent type of radiation in QED, there is no leading colour limit and the soft structure is more complicated. In this talk, I will discuss how we are including photonic emissions into the Vincia...
Following the recent measurements I did within the CMS collaboration I will bring up some still remaining open issues in closely back-to-back dijet topologies in 2- and 3-jet inclusive events. There are considerable differences observed (up to 15%) and 2- and 3-jet data is not described by any of the models considered simultaneously. Also the unexpected behavior of Madgraph interfaced with...
