The latest studentships to have started (see left for a full list):

New Biasing Method for Variance Reduction of Compton Events in GEANT4

Student: 
Sunil Kumar
Date: 
July, 2019 to October, 2019
Sunil Kumar is a Ph.D. student at Panjab University, India, on a three-month MCnet studentship in Durham. The project was in the collaboration of Durham University and IBEX Innovations Ltd. The aim of the studentship was to develop a biasing method which can be used to reduce the variance of low and high angle Compton scattered events from a pencil beam of X-rays interacting with a sample.

Investigating singularities in NLO splitting kernels

Student: 
Emma Simpson Dore
Date: 
September, 2018 to December, 2018

The parton shower in Herwig is the product of many years of continuous development and its main purpose is to evolve the event from the hard energy scale to an infrared cutoff scale where non-perturbative hadronisation models take over. The next step in development of the shower is to include higher orders to increase the logarithmic accuracy. This requires the implementation of splitting functions for two or more emissions which involves the organisation and bookkeeping of the singularity structures of QCD cross sections.

Space time colour reconnection in Herwig

Student: 
Cody Duncan
Date: 
April, 2018 to October, 2018

The MCnet short-term project aimed at implementing a complete description of spacetime coordinates and evolution during event generation in Herwig 7. The current version of Herwig, as with most other event generators, is formulated in an energy-momentum picture, with no concrete understanding of geometry and spacetime information generation. After a high-energy collision, outgoing QCD partons will undergo bremsstrahlung, lowering their energy more and more until reaching the non-perturbative, low-energy regime of QCD.

Azimuthal di-jet correlations

Student: 
Armando Bermudez Martinez
Date: 
April, 2018 to October, 2018

Recently in CMS, we have measured the azimuthal separation between the two leading jets in multi-jet events when these are approximately back-to-back. We have also measured the more exclusive and complementary azimuthal separation between the leading jets when the presence of at least an extra much softer jet is required in the event. We have observed a tension between the data and the theory predictions from parton shower event generators as well as from improved predictions using higher order matrix elements.
