PhD project: High Energy Jets

Project description

The start of LHC Run 2 gives particle collisions at an even greater centre-of-mass energy.  This is an exciting opportunity for new physics discoveries, but also poses a problem to our theoretical predictions.  The large range of energy scales can damage the convergence of the perturbative expansion through the appearance of logarithms at all orders in the coupling.  The High Energy Jets framework is a perturbative framework incorporating these corrections at all orders in the coupling at the matrix-element level which is then implemented as a fully-flexible event generator. This approach has been seen to describe LHC data well, including some important cases where more traditional approaches have failed.  Current priorities include moving to next-to-leading order accuracy and further enhancing the description through merging with parton showers.
