UF News online
The UF team involved in this discovery includes Bartos, Sergey Klimenko, Guenakh Mitselmakher, David Tanner, Guido Mueller, Bernard Whiting, Paul Fulda, Steve Eikenberry and John Conklin as well as David Reitze who is the Director of the LIGO Laboratory responsible for the whole project.
Gravitational waves detected 100 years after Einstein’s prediction
UF News online
Coherent WaveBurst, was developed at the University of Florida by physics professors Sergey Klimenko and Guenakh Mitselmakher, and their graduate students and postdoctoral research associates. Klimenko and Mitselmakher have been leaders in LIGO’s search for gravitational-wave bursts since 1997. The burst search seeks to detect short gravitational-wave signals from supernovae, gamma-ray bursts, mergers of binary neutron stars and black holes, and other catastrophic astrophysical events.
Measurements of production cross sections of WZ and same-sign WW boson pairs in association with two jets in proton-proton collisions atPhysics Letters B
Measurements of production cross sections of and same-sign boson pairs in association with two jets in proton-proton collisions at at the LHC are reported. The data sample corresponds to an integrated luminosity of 137, collected with the CMS detector during 2016–2018. The measurements are performed in the leptonic decay modes Image 1 and Image 2, where , Image 3.
Measurement of CKM matrix elements in single top quark t-channel production in proton-proton collisions atPhysics Letters B
The first direct, model-independent measurement is presented of the modulus of the Cabibbo–Kobayashi–Maskawa (CKM) matrix elements , , and , in final states enriched in single top quark t-channel events. The analysis uses proton-proton collision data from the LHC, collected during 2016 by the CMS experiment, at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb−1.
A facility to search for hidden particles at the CERN SPS: the SHiP physics caseReports on Progress in Physics
This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP (search for hidden particles) experiment is intended to hunt for new physics in the largely unexplored domain of very weakly interacting particles with masses below the Fermi scale, inaccessible to the LHC experiments, and to study tau neutrino physics.
Detector description and performance for the first coincidence observations between LIGO and GEONuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
For 17 days in August and September 2002, the LIGO and GEO interferometer gravitational wave detectors were operated in coincidence to produce their first data for scientific analysis. Although the detectors were still far from their design sensitivity levels, the data can be used to place better upper limits on the flux of gravitational waves incident on the earth than previous direct measurements.
Reconstruction of chirp mass in searches for gravitational wave transientsClassical and Quantum Gravity
The excess energy method is used in searches for gravitational waves (GWs) produced by sources with poorly modeled characteristics. It identifies GW events by searching for coincident excess energy in a GW detector network. While it is sensitive to a wide range of signal morphologies, the energy outliers can be populated by background noise events (background), thereby reducing the statistical confidence of a true signal.
