    • Cosmic Ray Signatures from Decaying Gravitino Dark Matter 

      Bomark, Nils-Erik; Lola, Smaragda; Osland, Per; Raklev, Are R. (Journal article; Peer reviewed, 2010)
      We study the charged cosmic rays arising from the slow decay of gravitino dark matter within supersymmetric scenarios with trilinear R-parity violation. It is shown that operators of the LLE type can very well account for ...

    • CP Violation in the scalar sector 

      Emmanuel-Costa, David; Øgreid, Odd Magne; Osland, Per; Rebelo, Margarida N. (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 ...

    • Light scalars in the Weinberg 3HDM potential with spontaneous CP violation 

      Plantey, Robin Maurice Yves; Øgreid, Odd Magne; Osland, Per; Rebelo, Margarida N.; Solberg, Marius (Journal article; Peer reviewed, 2022)
      The Z2×Z2-symmetric 3HDM potential, sometimes called Weinberg's 3HDM potential, can accommodate both explicit and spontaneous CP violation as well as natural flavour conservation and is hence relevant for studies of CP ...

    • Preliminary results of 3D-DDTC pixel detectors for the ATLAS upgrade 

      La Rosa, A; Boscardin, M; Dalla Betta, G.-F.; Darbo, G; Gemme, C; Pernegger, H; Piemonte, C; Povoli, M; Ronchin, S; Zoboli, A; Zorzi, N; Bolle, Erlend; Borri, M; Da Via, C; Dong, S; Fazio, S; Grenier, P; Grinstein, S; Gjersdal, H; Hansson, P; Huegging, F; Jackson, P; Kocian, M; Riviero, F; Røhne, Ole Myren; Sandaker, Heidi; Sjøbak, K; Slavicek, T; Tsung, W; Tsybychev, D; Wermes, N; Young, C (Journal article, 2009)
      3D Silicon sensors fabricated at FBK-irst with the Double-side Double Type Column (DDTC) approach and columnar electrodes only partially etched through p-type substrates were tested in laboratory and in a 1.35 Tesla magnetic ...

    • Testing the presence of CP violation in the 2HDM 

      Grzadkowski, Bohdan; Øgreid, Odd Magne; Osland, Per (Peer reviewed; Journal article, 2015-04-27)
      We review CP properties of the Two-Higgs-Doublet model. In particular, we show that sponta- neous CP violation occurs in the parameter space on the border between regions allowing explicit CP violation and those where there ...

    • Two dark matter candidates in three-Higgs-doublet models with S3 symmetry 

      Kuncinas, Anton; Øgreid, Odd Magne; Osland, Per; Rebelo, Margarida Nesbitt (Journal article; Peer reviewed, 2022)
      Models with an extended scalar electroweak sector can have vanishing vacuum expectation values in a basis where an underlying symmetry is imposed. Such extensions are very well motivated. If a symmetry prevents couplings ...

    • Update on the CP-Violating Inert-Doublet Model 

      Grzadkowski, Bohdan; Øgreid, Odd Magne; Osland, Per; Pukhov, Alexander; Purmohammadi, Mahdi (Peer reviewed; Journal article, 2012)
      We have updated a recently proposed extension of the Inert Doublet Model. The extension amounts to the addition of an extra non-inert scalar doublet. The model thus offers a possibility of CP violation in the scalar sector ...
