• CP violation in extended Higgs sectors 

      Øgreid, Odd Magne; Osland, Per; Rebelo, Margarida N. (Peer reviewed; Journal article, 2018-08-24)
      We discuss how one can identify CP violation (and conservation) in multi-Higgs-doublet potentials. After a brief review of CP violation in the 2HDM, we refer to the fact that for NHDM with N ≥ 3 the well known methods ...
    • CP Violation in the scalar sector 

      Emmanuel-Costa, David; Øgreid, Odd Magne; Osland, Per; Rebelo, Margarida N. (Conference object; Peer reviewed; Journal article, 2016)
      Models with an extended scalar sector may in principle provide new sources of CP violation originating in the scalar potential. One of the simplest ways to implement this idea is to have CP violation in a two-Higgs-doublet ...
    • Development of Readout Electronics for a Digital Tracking Calorimeter 

      Grøttvik, Ola Slettevoll; Ullaland, Kjetil; Alme, Johan; Eikeland, Viljar Nilsen; Nesbø, Simon Voigt; Røhrich, Dieter; Tambave, Ganesh Jagannath; Yang, Shiming (Journal article; Peer reviewed, 2020)
      Highly segmented digital tracking calorimeters consist of multiple layers of high-granularity pixel detector CMOS sensors and absorption/conversion layers. Two separate prototypes are being developed: (1) an electromagnetic ...
    • First irradiation test results of the ALICE SAMPA ASIC 

      Mahmood, Sohail Musa; Røed, Ketil; Velure, Arild; Winje, Fredrik (Peer reviewed; Journal article, 2018)
      With the continuous scaling of the CMOS technology, the CMOS circuits are considered to be more tolerant to Single event Latchup (SEL) effects due to the reduction in the supply voltages. This paper reports the results ...
    • Implementation of a CAN bus interface for the Detector Control System in the ALICE ITS Upgrade 

      Nesbø, Simon Voigt; Alme, Johan; Bonora, Matthias; Ersdal, Magnus Rentsch; Giubilato, Piero; Helstrup, Håvard; Lupi, Matteo; Rinella, Gianluca Aglieri; Røhrich, Dieter; Schambach, Joachim; Velure, Arild; Yuan, Shiming (Journal article; Peer reviewed, 2020)
      For the Upgrade of the ALICE Experiment in Long Shutdown 2, a new Inner Tracking System (ITS) is being commissioned, based on the ALPIDE Monolitihic Active Pixel Sensor (MAPS) chip. Data readout from the ALPIDE chips is ...

      We have measured the radiation tolerance of chemical vapor deposition (CVD) diamond against protons and neutrons. The relative radiation damage constant of 24 GeV protons, 800 MeV protons, 70 MeV protons, and fast reactor ...
    • Simulations of Busy Probabilities in the ALPIDE Chip and the Upgraded ALICE ITS Detector

      For the Long Shutdown 2 (LS2) upgrade of the ITS detector in the ALICE experiment at the LHC, a novel pixel detector chip, the ALPIDE chip, has been developed. In the event of busy ALPIDE chips in the ITS detector, the ...
    • Small-Scale Crisis in Cosmology – Sterile Neutrinos to the Rescue? 

      Kersten, Jörn (Peer reviewed; Journal article, 2019-04-24)
      The ΛCDM standard model of cosmology is in excellent agreement with data on large scales but has difficulty explaining all observations on small scales. I discuss a simple particle physics model involving a new MeV-scale ...
