Upcoming Seminars

26/10/2016 NOTE time and place!

Gravitational Wave Symposium

26th October 14.00 Imperial College London, Blackett Laboratories LT1 lecture theatre
A half day physics meeting on gravitational waves. Leading scientists from the Astro and HEP communities will present the recent discovery of gravitational waves and future prospects of this new field in fundamental physics. The talks are aimed at interested researchers at all levels across all of London's universities. See: https://indico.cern.ch/event/563302


28/10/2016 Jeff Foreshaw(Manchester) NOTE: earlier time: 3pm! different room: E7!

“Probabilities and Signalling in Quantum Field Theory”

I will talk about a way to compute transition probabilities that works directly that the level of probabilities and not amplitudes. The formalism guarantees that the initial and final states are always linked by a chain of retarded propagators and it has a nice diagrammatic approach.

exotic hadronic states in LHCb (Penta/Tetra quarks)

The latest years have seen a resurrection of interest in searches for exotic states. Using the data collected at pp collisions at 7 and 8 TeV by the LHCb experiment, unambiguous new observations of exotic charmonia hadrons produced in B and Lambdab decays are presented. Results of a search for a tetraquark state decaying to Bs pi+- are reported as well

Jet Production at NNLO

Jet production is one of the most ubiquitous yet important reactions at the LHC. Calculating higher order corrections to this observable allows us to gain sensitivity to phenomenological parameters such as the strong coupling and the gluon PDF as well as providing a rigorous test of QCD over a vast kinematic range. It is well known that calculating higher order corrections is a non-trivial task and requires a powerful method to subvert the various infrared singularities present in the calculation. I will introduce the Antenna Subtraction method as a means of calculating finite cross sections and present some recent results obtained by applying this method to the problem of jet production at NNLO.
