Superstatistical generalisations of Wishart-Laguerre ensembles of random matrices [PDF]

open access: yes, 2008
Using Beck and Cohen's superstatistics, we introduce in a systematic way a family of generalized Wishart–Laguerre ensembles of random matrices with Dyson index β = 1, 2 and 4. The entries of the data matrix are Gaussian random variables whose variances η

Confidence Interval Estimation for Intraclass Correlation Coefficient Under Unequal Family Sizes [PDF]

open access: yes, 2009
Confidence intervals (based on the χ2 -distribution and (Z) standard normal distribution) for the intraclass correlation coefficient under unequal family sizes based on a single multinormal sample have been proposed. It has been found that the confidence

Precise Measurement of the e+ e- --> pi+ pi- (gamma) Cross Section with the Initial-State Radiation Method at BABAR [PDF]

open access: yes, 2012
A precise measurement of the cross section of the process $e^+e^-\to\pi^+\pi^-(\gamma)$ from threshold to an energy of 3GeV is obtained with the initial-state radiation (ISR) method using 232fb$^{-1}$ of data collected with the BaBar detector at $e^+e^-$

Non-parametric comparison of histogrammed two-dimensional data distributions using the Energy Test [PDF]

open access: yes, 2012
When monitoring complex experiments, comparison is often made between regularly acquired histograms of data and reference histograms which represent the ideal state of the equipment.

Study of Monte Carlo approach to experimental uncertainty propagation with MSTW 2008 PDFs [PDF]

open access: yes, 2012
We investigate the Monte Carlo approach to propagation of experimental uncertainties within the context of the established "MSTW 2008" global analysis of parton distribution functions (PDFs) of the proton at next-to-leading order in the strong coupling ...

Re-visiting the relations: Galactic thin disc age-velocity dispersion relation [PDF]

open access: yes, 2007
The velocity dispersion of stars in the solar neighbourhood thin disc increases with time after star formation. Nordstrom et al. (2004) is the most recent observational attempt to constrain the age-velocity dispersion relation.

Fittino, a program for determining MSSM parameters from collider observables using an iterative method [PDF]

open access: yes, 2005
Provided that Supersymmetry (SUSY) is realized, the Large Hadron Collider (LHC) and the future International Linear Collider (ILC) may provide a wealth of precise data from SUSY processes.

Revisiting Radiation Patterns in $e^+e^-$ Collisions [PDF]

open access: yes, 2014
We propose four simple event-shape variables for semi-inclusive $e^+e^- \to 4$-jet events. The observables and cuts are designed to be especially sensitive to subleading aspects of the event structure, and allow to test the reliability of ...

Reconstruction and Particle Identification for a DIRC System [PDF]

open access: yes, 1998
We study the reconstruction and particle identification (PID) problem for Ring Imaging devices providing a good knowledge of the direction of the Cerenkov photons, as the DIRC system, on which we specialize. We advocate first the use of the stereographic

Variations on KamLAND: likelihood analysis and frequentist confidence regions

open access: yes, 2003
In this letter the robustness of the first results from the KamLAND reactor neutrino experiment with respect to variations in the statistical analysis is considered.
