Search for standard model production of four top quarks in the lepton + jets channel in pp collisions at TeV
James Keaveney
A search is presented for standard model (SM) production of four top quarks () in pp collisions in the lepton + jets channel. The data correspond to an integrated…
The Hilbert transform: Applications to atomic spectra
K. A. Whittaker, J. Keaveney, I. G. Hughes +1
In many areas of physics, the Kramers-Kronig (KK) relations are used to extract information about the real part of the optical response of a medium from its imaginary counterpart.…
Measurement of the cross section ratio sigma(t t-bar b b-bar) / sigma(t t-bar jj) in pp collisions at sqrt(s) = 8 TeV
CMS Collaboration
The first measurement of the cross section ratio sigma(t t-bar b b-bar) / sigma(t t-bar jj) is presented using a data sample corresponding to an integrated luminosity of 19.6 inver…
Probing an excited-state atomic transition using hyperfine quantum beat spectroscopy
Christopher G. Wade, Nikola Šibalić, James Keaveney +2
We describe a method to observe the dynamics of an excited-state transition in a room temperature atomic vapor using hyperfine quantum beats. Our experiment using cesium atoms cons…
Performance of the LHCb Vertex Locator
LHCb VELO Group, R. Aaij, A. Affolder +101
The Vertex Locator (VELO) is a silicon microstrip detector that surrounds the proton-proton interaction region in the LHCb experiment. The performance of the detector during the fi…
Optical response of gas-phase atoms at less than from a dielectric surface
K. A. Whittaker, J. Keaveney, I. G. Hughes +3
We present experimental observations of atom-light interactions within tens of nanometers (down to 11~nm) of a sapphire surface. Using photon counting we detect the fluorescence fr…
