Financial Rogue Trading and Market Abuse – Finding the Signal in the Noise

The actions of Jerome Kerviel and Kweku Adobole resulted in billion dollar losses for SocGen and UBS. Similarly, the FX and LIBOR scandals have seen banks fined in the hundreds of millions of dollars. This presentation asks why the banks struggle to identify the signals left by these traders. Topics covered include what the traders were doing in each case, the big data statistical approaches used by the anti-terrorist sections of the CIA and MI5 that have been co-opted by the banks and the unique statistical performance metrics used by TradingHub to solve the problem.

The amount of data from various sources: intelligence networks, traffic monitoring, social media, mobile phones, genomics, health etc) data now available for analysis has increased substantially in the last couple of years. However at the same time the requirements on the privacy of the underlying data have become more stringent requiring the need for algorithms to be developed that preserve the privacy of the underlying data while still extracting information with value (economic and otherwise). In this talk the algorithms and methodology being deployed by Privatar will be described.

“Search for Sphalerons: LHC vs. IceCube"

In a recent paper, Tye and Wong (TW) have argued that sphaleron-induced transitions in high-energy interactions should be enhanced compared to previous calculations, based on a construction of a Bloch wave function in the periodic sphaleron potential and the corresponding pass band structure. In this talk, I present our resent work studying future prospects of observing sphaleron transitions at high energy hadron colliders and IceCube, based on TW results. I first discuss the production rate and possible signatures of the sphaleron-induced processes at high energy hadron colliders. We recast the early ATLAS Run-2 search for microscopic black holes to constrain the rate of sphaleron transitions at 13 TeV LHC. In the second half of the talk, I will discuss the possibility of observing sphaleron transitions induced by cosmogenic neutrinos at IceCube. I calculate the sphaleron event rate at IceCube and discuss the signature of such events. Finally I compare the performance of the sphaleron searches at the LHC and IceCube and find complementarity of these experiments.

“The AEGIS experiment”

The AEGIS experiment, situated at the Antimatter Decelerator (AD) at CERN aim to measure for the first time the Earth’s gravitational acceleration of anti-Hydrogen. To achieve this the AEGIS collaboration plan to produce a pulsed cold anti-Hydrogen beam and send it through a classical Moire deflectometer before the anti-Hydrogen is detected by a system of position sensitive detectors. Beyond the gravitational measurements, AEGIS will also provide long-term anti-matter spectroscopy measurements. This talk will present both the scope and current status of the AEGIS experiment as well as discuss future measurements.
