### Research

A complete CV is available here, and a current list of publications can be found here.

Research Interests:

Eram Rizvi is a member of the ATLAS Collaboration at the LHC, and is studying the process of quark & anti-quark annihilation and the subsequent decay to muon and anti-muon. This process is sensitive to the distribution of quarks and gluons inside the proton, and therefore tells us about the dynamics of QCD - one of the four fundamental forces of nature. At high energies, this process is one of the main decay mechanisms for some new particles like a heavy Z' boson, or so-called Kaluza-Klein excitations of particles moving in hidden extra-dimensions.

Eram is also studying QCD in the Deep Inelastic Scattering of high energy electrons off the quark constituents of the proton at the H1 experiment in Hamburg, Germany. Precision measurements of the inclusive neutral and charged current cross sections provide complementary information about the quark and gluon content of the proton and his measurements allow stringent constraints to be placed on calculated processes at the LHC. These measurements are also sensitive to the Electroweak parts of the Standard Model and can be used to place limits on the quark radius.

He is also part of a small collaboration of theoreticians and experimentalists interested in the area of quantum gravity which has yet to be experimentally observed. It is hoped that at the very highest energy LHC collisions quantum gravity effects may become visible and lead to the production of micro black holes and the discovery of hidden extra-dimensions. Together with collaborators Eram has produced a state-of-the-art calculation and simulation of these processes, published as the computer program BlackMax which will help LHC physicists search for these new phenomena.

### Teaching

My teaching covers a variety of courses and topics which I have given since 2004 including:

#### Analysis Methods in High Energy Physics

This course aims to provide general background to experimental techniques often used in particle physics analyses. Detailed statistical techniques are not covered since there are many lectures covering these topics. Instead the lectures introduce the student to Monte Carlo simulations, what they are and their limitations. Event signatures are discussed as well as reweighting techniques and an introduction to acceptance corrections and bin purity. These lectures form part of the University of London Intercollegiate Lectures in Elementary Particle Physics. The lecture notes for this course are available here.

#### Graduate Lectures in Parton Density Functions

This was an invited lecture at a graduate school on the partond density functions of the proton as part of the Helmholtz Alliance graduate lecture series in Berlin 2008. The lecture notes for this lecture are available here.

#### Rutherford Summer School in High Energy Physics

The Rutherford Summer School on Experimental High Energy Physics runs in September each year for all 1st year graduate students and is a 2 week intensive residential school. I have participated in the school as a tutor in 2005-7.

#### Nuclear Physics and Astrophysics

The main part of my undergraduate teaching is a module on nuclear physics and astrophysics. This is a core 2nd year module and covers basic nuclear structure, decays, fusion, fisson, nucleosynthesis and cosmology. The module details are given here where a full set of lecture notes, and additional material is available. I have produced a series of podcasts and video for revision which is available for viewing and download.

#### Undergraduate Tutorials in Synoptic Physics

I have taken on tutorials for this compulsory final year module aimed at giving students an overview of the complete physics syllabus and how to apply physics principles in general situations. The module details are available online.

#### Undergraduate Lectures in Experimental Technique

I run the 1st year undergraduate lab course - Scientific Measurement. The module consists of 8-10 lectures on experimental technique followed by 2 lab sessions per week. The emphasis of the module was to foster good lab practice and the estimation of experimental uncertainties, statistical and systemtatic. The lecture notes are available here:
