The matrix element method utilizes ab initio calculations of probability densities as powerful discriminants to extract small signals from large backgrounds at hadron collider experiments. The computational complexity of this method for final states with many particles and degrees of freedom sets it at a disadvantage compared to supervised classification methods such as decision trees, k...

Fast 4pi solid angle particle track recognition has been a challenge in particle physics for a long time, especially in using nuclear emulsion detectors. In particular, the data rate from emulsion detectors, i.e. from a scanning microscope, is about 10-100 TB/day. Real-time 3D volume processing and track reconstruction of such a quantity of data without limiting the angular acceptance need a...

Gravitational wave physics is in the doorstep of a new, very exciting era. When the advanced Virgo and advanced LIGO detectors will start their operation, there will be considerable probability of performing the first direct detection of gravitational waves predicted almost 100 years ago by Einsten's theory of General Relativity.
However the extraction of the faint signal from the noisy...

Neutrino oscillation experiments are reaching high levels of precision in measurements, which are critical for the search for CP violation in the neutrino sector. Inclusion of matter effects increases the computational burden of oscillation probability calculations. The independency of reweighting individual events in a Monte Carlo sample lends itself to parallel implementation on a Graphics...
