Thursday 14th March: STP Seminar – “The electroweak monopole: the theory behind it, properties and its relevance in cosmology “
Title: The electroweak monopole: the theory behind it, properties and its relevance in cosmology
Speaker:Professor Yongmin Cho (Sogang University, Korea)
Abstract: The electroweak monopole in the standard model, the existence, characteristic features, cosmological production, and physical implications are discussed. The discovery of Higgs particle has been thought to be the ‘final’ test of the standard model. If the standard model is correct, however, it must have the electroweak monopole as the electroweak generalization of the Dirac monopole. This means that the detection of this monopole should become the final and topological test of the standard model. If detected, it becomes the first magnetically charged and stable topological elementary particle in the history of physics. Moreover, it has deep implications in physics. In cosmology it could generate the primordial magnetic black holes which could explain the dark matter, become the seed of the large scale structures of the universe, and be the source of the intergalactic magnetic field. As importantly, it could generate the hitherto unknown magnetic current that could have huge practical applications. Furthermore the existence of the monopole requires us to reformulate the perturbative expansion in quantum field theory. This makes the detection of the electroweak monopole a most urgent issue. Useful tips for the MoEDAL detector at LHC and similar experiments to detect the monopole are discussed.

Today marks the date of birth of John L. Synge, 1897-1995, who served as Director of the @StpDias from 1956 to 1969. Synge brought a new direction and dynamism to the School with interests in general relativity geometry and a broad interest in all fields of classical physics.

As of March 2019 there are 3,925 confirmed exoplanets in the @NASA Exoplanet Archive. @petertgallagher explains how astrophysicists detect these planets by looking at light curves as they transit in front of stars. #DIASdiscovers
Prof @petertgallagher kicks off with an apt quote from Schrödinger, ‘Some of us should adventure to embark on a syntheses of facts and theories....and the risk of making fools of ourselves’ #DIASdiscovers
Today at DIAS Professor @petertgallagher is answering the question ‘What is Extra-terrestrial Life?’. This is the first talk in a four-part public lecture series exploring ‘What is Life?’, famously considered by Professor Erwin Schrödinger in 1943. #DIASdiscovers
Tomorrow, at 1pm, Professor @petertgallagher will ask “What is Extra-terrestrial Life?” in the first of a four part public lecture series. There are a limited number of places still available - reserve your place free of charge at bit.ly/2HEJfYN. #DIASdiscovers
