Higgs physics, Beyond the Standard Model (BSM) physics and LHC<\/b><\/h3>

We use ML to study the LHC sensitivity to the Higgs self-coupling in VHH production with DNNs. We also use supervised \/ unsupervised \/ weakly supervised taggers for complex objects: multi-pronged jets, jets containing prompt non-hadronic objects, jets containing non-hadronic objects with displaced vertices, collimated non-hadronic objects. We also perform automated searches for BSM physics via direct searches for new physics with unsupervised methods.<\/p><\/div>

Cosmology, Dark Energy, Gravitational Waves<\/b><\/h3>

We use Genetic Algorithms in order to make model independent reconstructions of the expansion history of the Universe and the evolution of matter perturbations, along with null (=consistency) tests of the cosmological constant model. We also train Neural Networks to detect gravitational wave events and extract cosmological parameters, in particular in the case of hyperbolic encounters which have unique signatures for Primordial Black Holes.<\/p>

Astroparticle Physics and Dark Matter (DM)<\/b><\/h3>

We use ML to perform signal\/background discrimination in direct DM detection experiments (evolving from early boosted decision trees) and at the LHC (monojet, monophoton). We also use of deep learning to obtain the DM density profile (useful mainly for the inner parts of the galaxies) and ML algorithms to disentangle between standard astrophysical sources and dark matter subhalos.<\/p>

Theoretical Condensed Matter and Quantum Information<\/b><\/h3>

We apply ML techniques to mitigate the error in the present noisy quantum computers. With a combination of ML and tensor network techniques we can design more efficient algorithms. We also work to incorporate quantum logic into ML, in what is known as quantum ML.<\/p>

Top Physics<\/b><\/h3>

We use CNNs feed with jet images to create hadronic and leptonic top taggers.<\/p>

High Energy QCD<\/b><\/h3>

We use ML and AI techniques to detect and classify multi-particle final states at hadron colliders.<\/p>
