First Measurement of Bose-Einstein Correlations in Proton-Proton Collisions at √s=0.9 and 2.36 TeV at the LHC
(2010)Physical Review LettersBose-Einstein correlations have been measured using samples of proton-proton collisions at 0.9 and 2.36 TeV center-of-mass energies, recorded by the CMS experiment at the CERN Large Hadron Collider. The signal is observed in the form of an enhancement of pairs of same-sign charged particles with small relative four-momentum. The size of the correlated particle emission region is seen to increase significantly with the particle multiplicity ...Journal Article -
Measurement of the D*± meson production cross section and F 2c, ̄c at high Q2 in ep scattering at HERA
(2010)Physics Letters BThe inclusive production of D * ± (2010) mesons in deep-inelastic e ± p scattering is measured in the kinematic region of photon virtuality 100 < Q 2 < 1000 GeV 2 and inelasticity 0.02 < y < 0.7. Single and double differential cross sections for inclusive D * meson production are measured in the visible range defined by | η (D *) | < 1.5 and p T (D *) > 1.5 GeV. The data were collected by the H1 experiment during the period from 2004 to ...Journal Article -
A preliminary early-season flower- visitation web for the Kirindy forest, Madagascar
(2010)Journal of Pollination EcologyTropical dry deciduous forest is an endangered ecosystem whose plant-pollinator relationships are little known. We characterised a portion of the web of interactions between flowering plants and flower visitors in the Kirindy Forest of the Menabe region of west-central Madagascar. Taking a plant-centered approach, we observed individuals of the 5 most abundant native plant species that were coming into flower at the end of the annual dry ...Journal Article
