IPPP Summer Studentships 2017:

The IPPP will offer again this summer the possibility of working on a project in theoretical particle physics for about three weeks in Summer 2017. The topic and the names of the supervisors are given below. The exact dates can be agreed individually with the supervisor; successful applicants will receive 100 pounds per week from the IPPP. In the previous years this turned out to be a very successful program. Three years ago some of the students managed even to write a publication. The deadline for the application is 27th March 2017.

Interested students should contact alexander.lenz@durham.ac.uk.

 

Simon Badger - Introduction to modern amplitude methods

On-shell scattering amplitudes are the fundamental quantities that allow us to make theoretical predictions
for collider experiments. Traditional approaches to their computation are so difficult that many important quantities
are still unknown. On the other hand, final expressions are often remarkably simple and point to a deeper underlying mathematical
structure. Understanding these simplicities has led to new methods and new connections between mathematics and physics.
The aim of this project is to study some of the basic properties of scattering amplitudes and uncover the hidden simplicity
using new methods.

 

David Cerdeno - Introduction to the detection of dark matter particles

Astrophysical and cosmological evidence indicates that the majority of the matter in the Universe takes the form of non-luminous particles known as dark matter. The detection and identification of this new kind of matter constitutes one of the main open problems in modern Astroparticle Physics. In this project we will investigate ways to detect these particles in experiments on Earth, through their collisions with a target material.

 

Frank Krauss and Holger Schulz - Professor Framework

Recent studies have demonstrated the capabilities of parametrisation based approaches when constraining physics models beyond the standard model by means of numerical minimisation. Aim of this project is to implement analytic gradients into the Professor software (Python) in order to drastically reduce the run-time of the minimisation. This will in turn allow for significant progress in the exploration and constraining of high dimensional
parameter spaces frequently found in new physics models.

Alexander Lenz - Indirect Searches for New Physics

New unknown fundamental particles could be produced directly in particle accelerators, if the collider energy is larger than the masses of the new particles. In addition such new particle would also have a more subtle effect, they would modify many experimental observables via virtual effects. In the project such virtual effects will be investigated assuming that the standard model of particle physics is extended by additional particles. The theory results will be compared with recent experimental results, mostly from LHCb at the Large Hadron Collider.

 

Daniel Maitre - Introduction to Nuclear and Particle  Physics

This project involves helping to devise exercises and support material for the NPP module. The additional module will help NPP students to grasp and explore complicated concepts without the usual algebraic manipulation.

 

Peter Ballett - Neutrino Physics

The neutrino sector of the Standard Model (SM) of particle physics is known to be incomplete. Last year's Nobel Prize recognized the discovery of an effect known as neutrino oscillation, which is understood as direct evidence for non-zero neutrino masses and provides a startling contradiction to the massless neutrinos of the SM. Physicists at the IPPP are currently working on many topics relating to the construction of better theoretical explanations of the neutrino sector and how we can learn more about these particles at current and future experiments. If you are interested in working on a topic in this field, please free to get in touch by email: peter.ballett@durham.ac.uk.

 

David Grellscheid - Contur

Contur is a tool to constrain new physics with collider measurements of Standard Model signatures.
Information about Contur can be found at https://arxiv.org/abs/1606.05296

 

 

Michael Spannowsky - Higgs Physics

The project will focus on improving methods to search for new particles at the LHC. These methods will be tested on pseudodata and will allow current LHC experiments to increase their sensitivity. The project is related to data-intensive science (Big data) and machine-learning. Some expertise in programming is required and some knowledge of particle phenomenology can be beneficial.
