Title: An M5-Brane Model
Speaker: Christian Sämann (Heriot-Watt University)
Abstract: We show how to write an action for a classical six-dimensional superconfomal field theory containing a non-abelian tensor multiplet. All of the ingredients of this action have been available in the literature. We bring these pieces together by choosing the String Lie 2-algebra as a gauge structure which we motivate in some detail. The kinematical data contain a connection on a categorified principal bundle, which is the appropriate mathematical description of the parallel transport of self-dual strings. Our action can be written down for each of the simply laced Dynkin diagrams, and each case reduces to a four-dimensional supersymmetric Yang–Mills theory with corresponding gauge Lie algebra. Our action also reduces nicely to an M2-brane model which is a deformation of the ABJM model.
Time: Tuesday 5th December 2017, 2.30pm.
Place: Lecture Room, School of Theoretical Physics, DIAS, 10 Burlington Road, Dublin 4.

#DidYouKnow that we have repository of research publications showcasing the research of our professors, staff and scholars at DIAS? From academic papers, to technical reports, you can access it at: bit.ly/2V9GL87 #DIASdiscovers
J.L. Synge was a Senior Professor in the @StpDias from 1948 to 1972. You can read some Synge's original articles detailing his research and groundbreaking discoveries on our online repository at: bit.ly/2Gzh7X6 #DIASdiscovers
'Only a 1/4 of the 120,000 people working in jobs using #STEM are women ... girls are steering clear of what could be a universe of academic and career possibilities' Great article in the @IrishTimes with a mention of our first female fellow Sheila Tinney. bit.ly/2ElqOGu
DIAS iMARL infrastructure deploying ocean bottom seismometers which detect earthquakes and major weather events, track the presence of whales and dolphins, and capture seabed images. #DIASdiscovers
Great article in today's @IrishTimes about the breakthrough in understanding #SolarStorms, that was made by DIAS in conjuction with @tcddublin and @helsinkiuni. Read it at bit.ly/2Nd86ne. #DIASdiscovers
If you missed @petertgallagher Head of @DIASAstronomy, on @drivetimerte yesterday talking about our recent breakthrough on #SolarStorms, you can listen back at: bit.ly/2Sd1Yfm #DIASdiscovers

#DidYouKnow The School of Cosmic Physics at DIAS carried out the first gravity survey of Ireland and through off-shore geophysical research enabled the extension of Ireland’s ocean territory by tenfold. #DIASdiscovers
A key priority of the @SCSLibrary is the provision of reliable editions of hitherto unpublished material and texts, previously accessible only to scholars consulting the manuscripts. Learn more about the @DIAS_ISOS project at isos.dias.ie #DIASdiscovers
. @ProfBrianCox & @robinince using coffee & cream to explain how we got from the Big Bang to the universe as we know it today. Fantastic show tonight in @3ArenaDublin - masterclass in communicating complex scientific concepts effectively
@UniversalQandA Given you’re in Dublin, any comments on the legacy / influence of Schrödinger, who lived here for many years & was the first Director of @StpDias?
. @ProfBrianCox showing an image of the universe as it was 380,000 years after The Big Bang #Cosmology
“Your theory suggests there was a day without a yesterday” - Lemaître’s comment to Einstein on the Theory of Relativity, as cited by @ProfBrianCox
“9000 people have come out on a Saturday night to chat about #Cosmology - that makes me feel good about the world” - @ProfBrianCox is pleased with the turnout for his Dublin show :)
We’re excited to be @3ArenaDublin tonight for @ProfBrianCox. We know he’s a big fan of #Schrödinger, first Director of @StpDias, so looking forward to seeing if he speaks of Schrödinger‘s time in Dublin...
