The Theoretical Particle Physics group is mainly active in particle physics phenomenology. Work which relates theory to quantitative predictions for collider experiments. The group is subdivided into smaller, more informal, research groups centered around different research areas, which again are clustered into different categories, centered around the individual researchers' projects. They includ

The theory group in Lund has been a pioneer in the field of event generators for high energy physics, with particular emphasis on Quantum Chromodynamics (QCD), since the inception of the field in the late 1970s. Today seven seniors, Christian Bierlich, Rikkert Frederix, Gösta Gustafson (emeritus), Leif Lönnblad, Malin Sjödahl, Torbjörn Sjöstrand (emeritus) and Korinna Zapp all work on various aspe

The PYTHIA Monte Carlo event generator is one of the most widely used pieces of event generator software in the world. Originally a Lund University project, it is now maintained by an international collaboration with members from around the world. The PYTHIA program aims to deliver a full description of all aspects of collisions between particles such as electrons, protons, photons and heavy nucle

Low-energy particle physics is an area of particle physics covering most things not done at the highest energies. It encompasses what goes under the names of flavour-, precision- and hadronic physics and has strong connections to some areas of nuclear physics. Within the Lund theory group, Johan Bijnens, together with students and post docs, works on projects within all these aspects. In the histo

Physics beyond the Standard Model refers to the search for a phenomenologically consistent theoretical framework providing a first-principle explanation of the known properties and deficiencies of the Standard Model being a low-energy effective field theory limit of a more fundamental ultraviolet-complete theory. Currently the group consists of two seniors: Roman Pasechnik and Johan Rathsman. Desp

The division organises regular seminars, traditionally known as Science Coffee, usually alternating between experimental and theoretical research topics. Science coffee seminars can sometimes be replaced with informal seminars, usually on topics with a more narrow scope. The normal starting time is Tuesdays at 11:15. Organizers are Alice Ohlson (experiment) and Roman Pasechnik (theory).  Seminar c

Bachelor and Master projects Computing in particle physics experiments Modern Particle Physics is also appropriately called High Energy Physics, because it relies upon accelerators delivering high-energy particle collisions in order to generate data. Gone are the days when particle physicists were climbing mountains with photographic plates, hoping to register rare particles coming from collisions

Bachelor and Master projects ATLAS experiment at CERN The ATLAS experiment is one of the two largest experiments at the Large Hadron Collider (LHC) at CERN. ATLAS is designed to search for new particles in proton-proton collisions at this world's most powerful accelerator, which saw first particle collisions in late 2009. Together with another large experiment (CMS), ATLAS announced the discovery

Bachelor and Master projects ALICE experiment at CERN The ALICE experiment is one of the four large experiments at the Large Hadron Collider (LHC) at CERN. It is dedicated to the study of the quark-gluon plasma (QGP), a new state of matter in which quarks and gluons are deconfined. The Lund ALICE group is involved in both data analysis and hardware development for upgrades and even a possible futu

Bachelor and Master projects The Lund group is deeply involved in the development of several Monte Carlo event generators, used for simulating collision events as they arise in high energy experiments. There are possibilities for several different kinds of bachelor and master projects, in the full spectrum between projects which are very theoretical, and projects which are very close to experiment
