Beyond The Standard Model with Standard Model Effective Field Theory?
Abstract
The Standard Model Effective Field Theory (SMEFT) is an efficient tool for maximizing the use of Large Hadron Collider (LHC) data to probe possible extensions of the Standard Model. In this talk, the speaker will describe the results from a global analysis of possible dimension-6 SMEFT operators using LHC and other data, including various searches for physics beyond the Standard Model such as supersymmetry. He will also present results from studies of LHC constraints on new physics from dimension-8 SMEFT operators, including a possible Born-Infeld extension of the Standard Model.”
About the speaker
Prof. John Ellis is a British theoretical physicist who currently holds the Clerk Maxwell Professorship of Theoretical Physics at King's College in London. After obtaining a PhD from Cambridge University and holding post-doctoral positions at SLAC and Caltech, from 1973 to 2011 he worked at CERN (Geneva), where he was Theory Division Leader for six years.
Prof. Ellis' research interests focus on the phenomenological aspects of elementary particle physics and its connections with astrophysics, cosmology and gravity. Much of his work relates directly to experiment: interpreting results of searches for new particles and exploring the physics that could be done with future accelerators. A proposal he made in 1976 led to the discovery of the gluon in 1979, and he was one of the first to study how the Higgs boson could be produced and discovered. He has authored over a thousand scientific papers, with over eighty thousand citations in total. He has been active recently in efforts to understand the Higgs particle discovered at CERN, comparing the properties of this particle with the predictions of the Standard Model, and using effective field theory to understand the implications of the discovery for extensions of the Standard Model such as supersymmetry and other possible new physics such as dark matter. He is also now studying possible future particle accelerators and experiments to measure gravitational waves.
Prof. Ellis was elected a Fellow of the Royal Society of London in 1985. He was appointed a Commander of the Order of the British Empire (CBE) in 2012 for his services to science and technology. In 2015, he was elected a Foreign Fellow of the Indian National Science Academy and a Foreign Member of the Estonian Academy of Sciences, and he has been awarded several honorary doctorates.
Prof. Ellis is an eloquent speaker, frequently invited to give public and educational lectures on particle physics and related topics. He is also well known for his relentless efforts to involve non-European nations and institutions in CERN scientific and technological activities.
