## BGU Physics Department()

### The High Energy Physics (HEP) Group()

Our interests include quantum field theory, string theory, particle phenomenology, cosmology, astroparticle physics, GUTs, QCD, integrable models. The group has been traditionally very strong in various aspects of gravitational theory and its interplay with quantum world. One of the hottest topics explored today is quantum black holes probed by the emitted gravitational waves in collisions of astrophysical black holes. The research, which may revolutionize our understanding of black holes in particular and quantum gravity in general, combines fundamentals of quantum gravity and string theory with a detailed comparison to data, a unique combination in Israel. Development of new theories of gravity based on non metric volume elements is another research direction pioneered at BGU. It has been successful in construction of dark energy dark matter unified models, quintessential inflation and provides a new way to address the cosmological constant problem. Gravitation theory in anti-de-Sitter space finds unique applications to generalized theory of transport, via the so called fluid-gravity correspondence. Among the new fields that are being developed are particle physics phenomenology, with a particular interest in theories beyond the Standard Model. The research focuses on strategies for new particle searches at the LHC, and develops measurement techniques for the LHC and future colliders. The HEP group is the only group in Israel that combines both theoretical and experimental effort in high energy nuclear physics. On the theoretical side this comes with unique expertise in high energy quantum chromo-dynamics, the theory of hadronic collisions. This is met with a new experimental trust in relativistic heavy ion collisions measured with the ATLAS experiment at the LHC. Relativistic heavy ion collisions are thought to produce a quark-gluon plasma; a state of matter in which the smallest constituents of matter are deconfined.
