  1. 21. Derivation of a transfer function to estimate the Z(vv)+jets background from photon+jets in a search for dark matter at the ATLAS detector

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

    Author : Emelie Olsson; [2019]
    Keywords : Physics and Astronomy;

    Abstract : It has for long been known that dark matter must exist in our universe. Despite massive efforts to detect dark matter, its constituents remain a mystery. One strategy to unveil this mystery is to produce dark matter by colliding Standard Model particles. READ MORE

  3. 22. Heteroleptic Copper (I) Complexes as Photosensitizers in Dye-Sensitized Solar Cells

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Angela Raffaella Pia Pizzichetti; [2019]
    Keywords : Dye-Sensitized Solar Cells; Chemical and Environmental Engineering; Photovoltaic; Copper I complexes;

    Abstract : Modern civilization highly depends on energy and finding alternative sources to fossil fuels becomes more and more necessary. The sun is the most abundant energy source available and exploiting it efficiently would result in a great environmental and economic breakthrough. READ MORE

  4. 23. 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

  5. 24. Evaluation Analysis of the UV-detector on the Mini-EUSO Space Telescope

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Matej Lukanovic; [2018]
    Keywords : Mini-EUSO; EUSO; Space Telescope;

    Abstract : Extragalactic charged particles, each with energies rising up to and beyond 1 Joule, have been studied for almost a century. Yet, no precise evidence have proven to show where they might originate from as their energy levels rise above the current familiar acceleration sources in outer space. READ MORE

  6. 25. Electrical and Optical Characterization of InAsP/InP Nanowire-Based Avalanche Photodetectors

    University essay from Högskolan i Halmstad/Fotonik

    Author : Praveen Kumar Singaravelu; Tawhidul Alam Mohammad; [2016]
    Keywords : ;

    Abstract : The availability of new manufacturing methodology in solid state physics makes it possible to grow nano-photonic devices for better performance and unique properties. In this thesis work, we use I-V and FTIR spectroscopy to study the electrical and optical properties of InAsP/InP nanowire-based array avalanche photodetectors for near infrared applications.
