Light Higgs bosons from a strongly interacting Higgs sector [PDF]

, 2001
The mass and the decay width of a Higgs boson in the minimal standard model are evaluated by a variational method in the limit of strong self-coupling interaction.

Quantum state magnification

, 2016
Quantum metrology exploits entangled states of particles to improve sensing precision beyond the limit achievable with uncorrelated particles. All previous methods required detection noise levels below this standard quantum limit to realize the benefits ...

Estimating the resolution limit of the map equation in community detection

, 2015
A community detection algorithm is considered to have a resolution limit if the scale of the smallest modules that can be resolved depends on the size of the analyzed subnetwork.

Numerical Optical Centroid Measurements

, 2013
Optical imaging methods are typically restricted to a resolution of order of the probing light wavelength $\lambda_p$ by the Rayleigh diffraction limit. This limit can be circumvented by making use of multiphoton detection of correlated $N$-photon states,

Calibration of a single atom detector for atomic micro chips [PDF]

, 2007
We experimentally investigate a scheme for detecting single atoms magnetically trapped on an atom chip. The detector is based on the photoionization of atoms and the subsequent detection of the generated ions.

Tratamento de dados censurados em estudos ambientais

Química Nova, 2014
Due to the inherent limitations of the analytical methods of measurement, environmental exposure data often present observations described as below a certain detection limit, also called left-censored data. Censored data directly interferes in almost all

ORT observations of the damped Lyman alpha system towards PKS 0201+113

, 1997
We report a deep radio search with the Ooty Radio Telescope (ORT) for the redshifted 21 cm absorption line from the damped Lyman alpha system seen at redshift 3.388 against the quasar PKS 0201+113.

TEM10 homodyne detection as an optimal small displacement and tilt measurements scheme [PDF]

, 2006
We report an experimental demonstration of optimal measurements of small displacement and tilt of a Gaussian beam - two conjugate variables - involving a homodyne detection with a TEM10 local oscillator.
