The present landscape and the open questions in particle physics will be briefly reviewed, showing that they call for new means of investigation both towards higher energy and towards more sensitivity to small couplings.
CERN is preparing actively, according to the recommendation of the 2013 European Strategy, for an ambitious post-LHC accelerator complex. The 100km circumference Future...
Searching for a difference between neutrino and anti-neutrino oscillations may open the way towards new fundamental physics and an explanation of why the world is made of only matter and no anti-matter. To discover such a difference, the development of a very large neutrino detector and a high-intensity neutrino beam is needed. The same detector will make possible investigations of...
I will present the first Beyond the Standard Model (BSM) global fit results obtained using the new Global And Modular BSM Inference Tool (GAMBIT). With GAMBIT we have analysed the GUT-motivated supersymmetry models CMSSM, NUHM1 and NUHM2; the weak-scale MSSM7; and a scalar singlet dark matter model. Our analyses improve on existing results in terms of the number of included observables and the...
The type-I seesaw mechanism, able to explain the lightness of the three active neutrinos, requires the existence of exotic heavy neutral fermions, with a mass ranging from a few MeV to around a TeV. We propose a model with three such sterile neutrinos where the mixing matrices are parametrized using the Casas-Ibarra scheme. Direct dectection constrains coming from DELPHI and ATLAS among others...
We study the prospects for using deep neural networks to distinguish collider signals from heavy and mass degenerate CP-odd and CP-even Higgs bosons. The close overlap in the kinematic features highlights a challenge related to the bias introduced by training data.
In order to improve track reconstruction in Run 2 and to prepare for the increasingly difficult detector conditions of Run 3 at the Compact Muon Solenoid (CMS) detector, the use of novel machine learning methods in the CMS tracking are being studied. These methods provide ways to deal with for example the high particle densities, growing combinatorics and track quality assignments in the...
In this Masters thesis we have developed a faster way to calculate
supersymmetric cross sections at next-to-leading order (NLO) by using
machine learning techniques. This method teaches the computer software
to imitate the cross section function, facilitating the evaluation of a
large number of parameter points in a short period of time. Training is
carried out based on data generated with...
Particle physics experiments typically require that background processes affecting the measurement are taken into account in the data analysis. In collider experiments, this means estimating how large fraction of the observed collision events actually originate from background processes and not from signal events.
The background event yields are usually estimated from simulation or with a...
Since Norwegian high school teacher are required to teach particle physics, it is important to give them as good an understanding of the topic as possible. Since also many students who does not venture into more advanced physics courses, show an interest in particle physics, we face a challenge in how to teach these topics in a non-technical fashion. I will discuss aspects of coming to grips...
With the advent of higher energies and higher collision rates, the LHC continues the exciting voyage towards new physics, allowing physicists all over the world to explore a previously unknown territory full of promise. So far the International Particle Physics Outreach Group (IPPOG) international masterclass developers, with the help of physicists and in close contact with teachers, have been...
