  1. 36. Simulation of Higgs boson pair production in Vector Boson Fusion at the LHC

    University essay from Uppsala universitet/Högenergifysik

    Author : Daniela Romero; [2021]
    Keywords : Higgs boson; vbf; vector boson fusion; high energy physics; lhc; proton collision; madgraph; simulation;

    Abstract : MadGraph5 is used to generate events with Higgs boson pairs from vector boson fusion (VBF) at leading-order (LO) and next-to-leading-order (NLO) accuracy in QCD. The simulations are used to compute fiducial cross-sections in proton-proton collisions at a centre-of-mass energy of 13 TeV, using several kinematic cuts on the outgoing jets, e.g. READ MORE

  3. 37. Characterisation of Low-Level Jets and their Influence on Low-Level Clouds over the Baltic Sea; Östergarnsholm Observatory, Sweden

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Johan Lundberg; [2021]
    Keywords : Low-level jets; Low-level clouds; LLJs; LLCs; Boundary layer; ABL; CBH; Lidar; Ceilometer; Turbulent intensity; Physics and Astronomy;

    Abstract : In this study, about two years of data from Östergarnsholm in the Baltic Sea are used to analyse offshore low-level clouds (LLCs) influenced by low-level jets (LLJs) in the marine atmospheric boundary layer. The LLJs are passages of strong horizontal winds near the surface and are measured using a Doppler LiDAR, which provides information about the wind speed and wind direction up to 300 meters.

  4. 38. Searching for Dark Photons with Jet

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Ashar Ahmed Kamal; [2020]
    Keywords : light dark matter; jet substructure; Physics and Astronomy;

    Abstract : Dark matter is the greatest mystery of modern particle physics and cosmology. Although an overwhelming amount of observational cosmological evidence has pointed towards a dark sector, only its gravitational effect has been experimentally confirmed. READ MORE

  5. 39. Tests of Autoencoder Compression of Trigger Jets in the ATLAS Experiment

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Erik Wallin; [2020]
    Keywords : Physics and Astronomy;

    Abstract : Limited data storage capability is a large obstacle for saving data in high energy particle physics. One method of partially circumventing these limitations, is trigger level analysis (TLA) as used by the ATLAS experiment. The efficiency of TLA can be further increased by doing effective data compression. READ MORE

  6. 40. Investigating RT using two-particle angular correlations in proton-proton collisions

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Dilan Chroscik; [2020]
    Keywords : particle physics; proton-proton collisions; two-particle angular correlations; underlying event; relative transverse activity; ALICE; LHC; collective flow; long range correlations; Physics and Astronomy;

    Abstract : The observable, RT , is investigated using two-dimensional (∆η, ∆φ) angular correlations, where ∆η and ∆φ are the differences in pseudorapidity and azimuthal angle respectively, between the trigger and associated tracks. The analysed data consists of reconstructed tracks, from proton-proton collisions at collision energy ps = 13 TeV, taken from the ALICE detector at the LHC. READ MORE
