(författare) Search for charged Higgs bosons at LEP 2 1999 Ingår i: PHYSICS LETTERS B. - : ELSEVIER SCIENCE BV. - 0370-2693. ; 460:3-4, s. 484-497 Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract A search for pair produced charged Higgs bosons has been performed in the high energy data collected by DELPHI at LEP with root s = 161, 172 and 183 GeV. The analysis uses the tau nu tau nu, c (s) over bar tau nu and c<(sc)over bar>s final states and a co

(författare) Search for chargino pair production in scenarios with gravitino LSP and stau NLSP at root s similar to 183 GeV at LEP 1999 Ingår i: PHYSICS LETTERS B. - : ELSEVIER SCIENCE BV. - 0370-2693. ; 466:1, s. 61-70 Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract Promptly decaying lightest charginos were searched for in the context of scenarios with gravitino LSP. It was assumed that the stau is the next to lightest supersymmetric particle (NLSP). Data collected with the DELPHI detector at a centre-of-mass energy

(författare) Search for charginos in e(+)e(-) interactions at root s=189 GeV 2000 Ingår i: PHYSICS LETTERS B. - : ELSEVIER SCIENCE BV. - 0370-2693. ; 479:1-3, s. 129-143 Tidskriftsartikel (refereegranskat)abstract An update of the searches for charginos and gravitinos is presented, based on a data sample corresponding to the 158 pb(-1) recorded by the DELPHI detector in 1998, at a centre-of-mass energy of 189 GeV. No evidence for a signal was found. The lower mass
