Jonathan Cullen (Durham University)
In this talk I will discuss the Standard Model Effective Field Theory (SMEFT), a very general model to describe the interaction of the Standard Model with fields at masses far higher than those of the SM. I will discuss the necessity for, and techniques of using dimension-6 operators to compute decay rates and cross sections at next-to-leading order (NLO) and the phenomenological applications...
11. General Treatment of the Monopole Production Cross Sections by Drell-Yan and Photon Fusion for Three Spin Models
Ms Stephanie Baines ((King's College London) on behalf of the MoEDAL collaboration)
Recently there is a revived interest in monopole searches with masses accessible at current colliders, due to several theoretical models predicting the existence of light monopoles. However all of such models predict monopoles with structure (solitons), whose production at colliders may be strongly suppressed. On the other hand, there is no theory up to now for point-like monopoles, viewed as...
Mr Olivier Lennon (University of Oxford)
Motivated by recent constructions of TeV-scale strongly-coupled dynamics, either associated with the Higgs sector itself as in pseudo-Nambu-Goldstone boson (pNGB) Higgs models or in theories of asymmetric dark matter, I will discuss work where it was shown that stable solitonic Q-balls can be formed from light pion-like pNGB fields carrying a conserved global quantum number in the presence of...
Mr Dumitru Dan Smaranda (University of Glasgow)
The talk will give an overview of orbifold models in 5D and 6D and will revolve around the question of can non-trivial boundary conditions in the compactified dimensions (also known as Scherk-Schwartz twitsts) give a SM like low energy spectrum with a "naturaly" broken SUSY.
