A finite oscillator model with equidistant position spectrum based on an extension of
Roy Oste, Joris Van der Jeugt
We consider an extension of the real Lie algebra by introducing a parity operator and a parameter . This extended algebra is isomorphic to the Bannai-Ito…
The Wigner distribution function for the finite oscillator and Dyck paths
Roy Oste, Joris Van der Jeugt
Recently, a new definition for a Wigner distribution function for a one-dimensional finite quantum system, in which the position and momentum operators have a finite (multiplicity-…
Non-perturbative aspects of Euclidean Yang-Mills theories in linear covariant gauges: Nielsen identities and a BRST invariant two-point correlation function
M. A. L. Capri, D. Dudal, A. D. Pereira +5
In order to construct a gauge invariant two-point function in a Yang-Mills theory, we propose the use of the all-order gauge invariant transverse configurations A^h. Such configura…
UV-extended E-MILES stellar population models: young components in massive early-type galaxies
A. Vazdekis, M. Koleva, E. Ricciardelli +2
We present UV-extended E-MILES stellar population synthesis models covering the spectral range 1680-50000A at moderately high resolution. We employ the NGSL space-based stellar lib…
Very Thin Disc Galaxies in The SDSS Catalog of Edge-on Galaxies
D. V. Bizyaev, S. J. Kautsch, N. Ya. Sotnikova +2
We study the properties of galaxies with very thin discs using a sample of 85 objects whose stellar disc radial-to-vertical scale ratio determined from photometric decomposition, e…
Neutrino-Nucleus Cross Sections for Oscillation Experiments
Teppei Katori, Marco Martini
Neutrino oscillations physics is entered in the precision era. In this context accelerator-based neutrino experiments need a reduction of systematic errors to the level of a few pe…
