Abstract:

A measurement of the differential cross section for the inclusive production of isolated prompt photons in proton-proton collisions at a center-of-mass energy of 7 TeV is presented. The data sample corresponds to an integrated luminosity of 36pb-1 recorded by the CMS detector at the LHC. The measurement covers the pseudorapidity range |η|<2.5 and the transverse energy range 25

Abstract:

We report on a search for the production of the Higgs boson decaying to two bottom quarks accompanied by two additional quarks. The data sample used corresponds to an integrated luminosity of approximately 4fb-1 of pp̄ collisions at √s=1.96TeV recorded by the CDF II experiment. This search includes twice the integrated luminosity of the previous published result, uses analysis techniques to distinguish jets originating from light flavor quarks and those from gluon radiation, and adds sensitivity to a Higgs boson produced by vector boson fusion. We find no evidence of the Higgs boson and place limits on the Higgs boson production cross section for Higgs boson masses between 100GeV/c2 and 150GeV/c2 at the 95% confidence level. For a Higgs boson mass of 120GeV/c2, the observed (expected) limit is 10.5 (20.0) times the predicted standard model cross section. © 2011 American Physical Society.

FRATs: A search for Fast Radio Transients with LOFAR

Abstract:

The FRATs project aims to detect single dispersed pulses from Fast Radio Transients with LOFAR in real-time. These pulses can originate from pulsars, RRATS and other classes of known or unknown objects. To detect these pulses a detection algorithm is being run on an incoherent beam from the different LOFAR stations. This incoherent beam has a wide field of view and can be formed parallel to other observations, such that both can run at the same time. A precise localisation is done by storing the data from each dipole. This gives an all-sky coverage with a spatial resolution of order arc seconds. The source is identified by making high time-resolution images. This is explained in more detail with preliminary results illustrating the methods. © 2011 American Institute of Physics.
