ПРОБЛЕМА ПРОИСХОЖДЕНИЯ КОСМИЧЕСКИХ ЛУЧЕЙ СВЕРХВЫСОКИХ ЭНЕРГИЙ

Odessa Astronomical Publications, 2011
The problem of cosmic ray origin comes to two main questions: were and how cosmic particles are accelerated up to very high energies. In this paper, arguments in favor of two basic sources of cosmic rays (Galaxy and Metagalaxy) are considered and ...

Chiral Disorder in QCD [PDF]

, 1998
Using the Gell-Mann-Oakes-Renner (GOR) relation and semi-classical arguments, we show that the bulk quark spectrum in QCD exhibits a variety of regimes including the ergodic one described by random matrix theory. We analyze the quark spectral form-factor

Is Grammar Spared in Autism Spectrum Disorder? Data from Judgments of Verb Argument Structure Overgeneralization Errors [PDF]

Journal of Autism and Developmental Disorders, 2015
Children with Autism Spectrum Disorder (ASD) aged 11-13 (N = 16) and an IQ-matched typically developing (TD) group aged 7-12 (N = 16) completed a graded grammaticality judgment task, as well as a standardized test of cognitive function. In a departure from previous studies, the judgment task involved verb argument structure overgeneralization errors (e.

Anticipating Acene-Based Chromophore Spectra with Molecular Orbital Arguments. [PDF]

Journal of Physical Chemistry A, 2018
Recent synthetic studies on the organic molecules tetracene and pentacene have found certain dimers and oligomers to exhibit an intense absorption in the visible region of the spectrum that is not present in the monomer or many previously studied dimers.

Constituent Quarks and Gluons, Polyakov loop and the Hadron Resonance Gas Model *,**

EPJ Web of Conferences, 2014
Based on first principle QCD arguments, it has been argued in [1] that the vacuum expectation value of the Polyakov loop can be represented in the hadron resonance gas model.

Phases of New Physics in the BAO Spectrum [PDF]

, 2017
We show that the phase of the spectrum of baryon acoustic oscillations (BAO) is immune to the effects of nonlinear evolution. This suggests that any new physics that contributes to the initial phase of the BAO spectrum, such as extra light species in the

The very steep spectrum radio halo in Abell 697 [PDF]

, 2010
In this paper we present a detailed study of the giant radio halo in the galaxy cluster Abell 697, with the aim to constrain its origin and connection with the cluster dynamics.

Resummation improved rapidity spectrum for gluon fusion Higgs production [PDF]

, 2017
A bstractGluon-induced processes such as Higgs production typically exhibit large perturbative corrections. These partially arise from large virtual corrections to the gluon form factor, which at timelike momentum transfer contains Sudakov logarithms ...

About the Nature of the Spectrum of the Periodic Problem for the Heat Equation with a Deviating Argument [PDF]

Abstract and Applied Analysis, 2013
We study the nature of the spectrum of the periodic problem for the heat equation with a lower-order term and with a deviating argument. A significant influence of the lower-order term on the correct solvability of this problem is found. We obtain a criterion for the strong solvability of the above-mentioned problem.

Hitting sbottom in natural SUSY [PDF]

, 2012
We compare the experimental prospects of direct stop and sbottom pair production searches at the LHC. Such searches for stops are of great interest as they directly probe for states that are motivated by the SUSY solution to the hierarchy problem of the ...
