Searches for new physics in single-photon events and a search for charginos at the DELPHI experiment

A search for new physics using events with a single photon and missing energy has been made at the DELPHI experiment together with a search for charginos. The results were based on data collected up to and including the final year of 2000. An integrated luminosity of 650 pb<super>&minus;1&...

description A search for new physics using events with a single photon and missing energy has been made at the DELPHI experiment together with a search for charginos. The results were based on data collected up to and including the final year of 2000. An integrated luminosity of 650 pb<super>&minus;1</super> was used in the single photon analysis and 450 pb<super>&minus;1</super> in the chargino search. Center-of-mass energies up to 209 GeV were explored. Searches have been made for supersymmetry as well as for extra dimensions and non standard neutrino interactions. Since no signs of a signal have been observed in any of the searches the results have been used to set exclusion limits and to constrain the theoretical parameter spaces. The search results using single and acoplanar photon events from the four LEP experiments have also been combined within the searches for supersymmetry and extra dimensions.
