Conference Proceeding
HYPATIA (the Hybrid Pupil's Analysis Tool for Interactions in ATLAS) framework is designed to enable high school students and their teachers to study elementary particles and their interactions. This ...is provided by visualization of particle collisions detected by the ATLAS experiment at LHC, the world's most powerful particle accelerator located at the European Particle Research Centre (CERN). At the same time, HYPATIA provides access to relevant scientific analysis tools, inspiring students to become researches and introduces them to the environment of large-scale international collaborations.
Nucl.Instrum.Meth. A412 (1998) 465-474 This paper describes the use of weighted Monte Carlo events to accurately
approximate integrals of functions of the experimentally measured kinematical
vectors ...and their dependence on physical parameters. This technique is
demonstrated in estimating the evolution of cross sections, efficiencies,
measured kinematical distributions and mean values as functions of the
Trilinear Gauge Couplings.
Nucl.Instrum.Meth. A414 (1998) 399-417 This paper describes the definition of maximum likelihood equivalent
estimators of the Trilinear Gauge Couplings which include detector effects. The
asymptotic ...properties of these estimators as well as their unbiasedness and
efficiency when dealing with finite statistical samples are demonstrated by
Monte Carlo experimentation, using simulated events corresponding to the
production of q qbar lepton neutrino in e+ e- collisions at 172 GeV. Emphasis
is given to the determination of the expected efficiencies in extracting the
aWphi, aW and aBphi couplings from LEPII data, which in this particular case
found to be close to the maximum possible.
Nucl.Instrum.Meth. A564 (2006) 597-607 The front-end electronics of the ATLAS hadronic calorimeter (Tile Cal) is
housed in a unit, called {\it PMT-Block}. The PMT-Block is a compact instrument
...comprising a light mixer, a PMT together with its divider and a {\it 3-in-1}
card, which provides shaping, amplification and integration for the signals.
This instrument needs to be qualified before being assembled on the detector. A
PMT-Block test bench has been developed for this purpose. This test bench is a
system which allows fast, albeit accurate enough, measurements of the main
properties of a complete PMT-Block. The system, both hardware and software, and
the protocol used for the PMT-Blocks characterisation are described in detail
in this report. The results obtained in the test of about 10000 PMT-Blocks
needed for the instrumentation of the ATLAS (LHC-CERN) hadronic Tile
Calorimeter are also reported.
Nucl.Instrum.Meth. A430 (1999) 474-487 This paper describes the extension of the Modified Observables technique in
estimating simultaneously more than one Trilinear Gauge Couplings. The optimal
...properties, unbiasedness and consistent error estimation of this method are
demonstrated by Monte Carlo experimentation using $\ell \nu jj $ four-fermion
final state topologies. Emphasis is given in the determination of the expected
sensitivities in estimating the $\lambda_{\gamma} - \Delta g_{1}^{z}$ and
$\Delta k_{\gamma} - \Delta g_{1}^{z}$ pair of couplings with data from the 183
GeV LEPII run.
Nucl.Instrum.Meth. A430 (1999) 455-473 This paper describes two generalization schemes of the Optimal Variables
technique in estimating simultaneously two Trilinear Gauge Couplings. The first
is an ...iterative procedure to perform a 2-dimensional fit using the linear terms
of the expansion of the probability density function with respect to the
corresponding couplings, whilst the second is a clustering method of
probability distribution representation in five dimensions. The pair production
of W's at 183 GeV center of mass energy, where one W decays leptonically and
the other hadronically, was used to demonstrate the optimal properties of the
proposed estimation techniques.
