  1. 1. Studies of new light resonances decaying into two hadronic jets produced in association with a radiated jet

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

    Author : Zhiying Li; [2018]
    Keywords : dark matter mediator; ATLAS; dijet ISR jet; light resonance; ISR jet; dijet; trijet final state; kinematics variables; combinatorics; mass combinations; significance; thrust; LHC; CERN; Physics and Astronomy;

    Abstract : This report presents combinatorics studies in the search for a resonance of below 800GeVwhich decay product is a pair of hadronic jets from quarks. The resonance, predicted as a dark matter mediator, has couplings to dark matter particles as well as quarks and gluons. READ MORE

  3. 2. Search for High-Mass Dijet Resonances Decaying into Top Quark Pairs using Machine Learning Techniques in the ATLAS Experiment

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

    Author : Stefio Yosse Andrean; [2018]
    Keywords : ATLAS; LHC; jet; dijet; resonance; top; machine learning; BDT; DNN; topocluster; Physics and Astronomy;

    Abstract : This thesis presents an application of machine learning techniques in a search for a high-mass resonance particle decaying into top quark pairs in high energy dijet events using the ATLAS experiment at the Large Hadron Collider. Top tagging is applied to the dijet events to select the events with top signature and suppress the background, increasing the sensitivity of the search. READ MORE

  4. 3. Searches for Low-Mass Dijet Resonances in Trijet Final States using Monte Carlo Samples

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

    Author : Patrawan Pasuwan; [2016]
    Keywords : Dijet resonance; trijet final states; mass combination; sensitivity studies; composite quark model; simplifies dark matter mediator model; Physics and Astronomy;

    Abstract : This thesis presents the prototype of a search for new phenomena that decay in two jets, in presence of an associated jet (three-jet or trijet final state). Mass combination studies are carried out to reconstruct dijet resonances in different mass regions. READ MORE
