Search for an excess of events with an identical flavour lepton pair and significant missing transverse momentum in root s=7 TeV proton-proton collisions with the ATLAS detector
Results are presented of a search for supersymmetric particles decaying into final states with significant missing transverse momentum and exactly two identical flavour leptons (e or mu) of opposite charge in sqrt{s}=7 TeV collisions at the Large Hadron Collider. This channel is particularly sensitive to supersymmetric particle cascade decays producing flavour correlated lepton pairs. Flavour uncorrelated backgrounds are subtracted using a sample of opposite flavour lepton pair events. Observation of an excess beyond Standard Model expectations following this subtraction procedure would offer one of the best routes to measuring the masses of supersymmetric particles. In a data sample corres…
Myanmar’s semi-captive working elephant population is not sustainable without capture from the wild
Wildlife populations in captivity are increasingly common, but captive populations often have a higher extinction risk and may require supplementation through wild-capture. Despite this, wild-capture may actually hinder long-term conservation goals by reducing remaining wild populations, and its direct and long-term indirect consequences for captive population viability are rarely addressed using longitudinal data. Here, we explore the implications of changes in wild-capture on population viability over 54 years using a multi-generational studbook of working Asian elephants from Myanmar. We show that population viability declined between 1960 and 2014 with declines in wild-capture. Wild-cau…
