Search for lepton flavour violation in ep collisions at HERA

A search for the lepton flavour violating processes ep→μX and ep→τX is performed with the H1 experiment at HERA. Final states with a muon or tau and a hadronic jet are searched for in a data sample corresponding to an integrated luminosity of 66.5 pb-1 for e+p collisions and 13.7 pb-1 for e-p collisions at a centre-of-mass energy of 319 GeV. No evidence for lepton flavour violation is found. Limit

Nordic countries: Denmark, Norway and Sweden

The aims of the workpackage: The objective of WP3 is to provide an overview of policy formation and deliberation across a number of regions and across a relatively broad timeframe (late 1980s to the present). As a mapping exercise it is intended to provide an initial comparative framework for further elaboration in more detailed country and regional case studies. WP3 offers a ‗helicopter view‘ of
