Search for Heavy Neutral Leptons with LHCb

Serhii Cholak

This thesis presents a search for a beyond the Standard Model (SM) heavy neutral lepton (HNL), which does not interact via any of the SM interactions. This hypothetical particle has been proposed by multiple theories as an extension to the SM, and it could ...

REVIEW OF PARTICLE PHYSICS Particle Data Group

Olivier Schneider, Varun Sharma, Christophe Bauer, Greig Alan Cowan, Julien Lesgourgues, Riddhiman Sarkar, Vladimir Petrov, Florian Patrick Marie Daniel De la Barre De Nanteuil, Frank Zimmermann, Lorena Gonçalves de Alcântara e Freitas Krikler, Kai Oliver Arras

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 2,873 new measurements from 758 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, lepton ...

Neutral atom dynamics and plasma turbulence in the tokamak periphery

Christoph Wersal

Understanding the physical mechanisms at play in the interaction between turbulent plasma and neutral particles is a crucial issue that we approach in this Thesis by using a first-principles self-consistent model of the tokamak periphery implemented in the ...

Search for non-relativistic magnetic monopoles with IceCube

Shirit Cohen, Mathieu Ribordy, Matthias Wolf, Mark Tobin, Sofia Vallecorsa, Xiaoxia Bai

The IceCube Neutrino Observatory is a large Cherenkov detector instrumenting of Antarctic ice. The detector can be used to search for signatures of particle physics beyond the Standard Model. Here, we describe the search for non-relativistic, magnetic mono ...

Mixing patterns from the groups Sigma(n phi)

Lorenzo Vitale

We survey the mixing patterns which can be derived from the discrete groups Sigma(36 x 3), Sigma( 72 x 3), Sigma(216 x 3) and Sigma(360 x 3), if these are broken to Abelian subgroups G(e) and G(nu) in the charged lepton and neutrino sector, respectively. S ...

IceCube sensitivity for neutrino flux from Fermi blazars in quiescent states

Mathieu Ribordy

We investigate the IceCube detection potential of very high energy neutrinos from blazars, for different classes of hadronic models, taking into account the limits imposed on the neutrino flux by the recent Fermi telescope observations. Assuming the observ ...

Constraints on decaying dark matter from XMM-Newton observations of M31

Alexey Boyarsky, Oleg Ruchayskiy

We derive constraints on the parameters of the radiatively decaying dark matter (DM) particle, using the XMM-Newton EPIC spectra of the Andromeda galaxy (M31). Using the observations of the outer (5-13 arcmin) parts of M31, we improve the existing constrai ...
