Supersymmetry Parameter Analysis: SPA Convention and Project
J. A. Aguilar-Saavedra, A. Ali, B. C. Allanach +122
High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is…
Many-body nuclear Hamiltonian: Ab exitu approach
A. M. Shirokov, J. P. Vary, A. I. Mazur +1
Fully-microscopic No-core Shell Model (NCSM) calculations of all stable and shell nuclei are used to determine realistic interaction JISP16 describing not only the two…
Unintegrated gluon distributions in D* and dijet associated photoproduction at HERA
A. V. Lipatov, N. P. Zotov
We consider the photoproduction of D* mesons associated with two hadron jets at HERA collider in the framework of the kt-factorization approach. The unintegrated gluon densities in…
Leading twist moments of the neutron structure function F2n
M. Osipenko, W. Melnitchouk, S. Simula +2
We perform a global analysis of neutron F2n structure function data, obtained by combining proton and deuteron measurements over a large range of kinematics. From these data the lo…
Dynamics with Low-Level Fractionality
Vasily E. Tarasov, George M. Zaslavsky
The notion of fractional dynamics is related to equations of motion with one or a few terms with derivatives of a fractional order. This type of equation appears in the description…
Lorentz symmetry violation without violation of relativistic symmetry
G. Yu. Bogoslovsky
Within the framework of the Finslerian approach to the problem of violation of Lorentz symmetry, consideration is given to a flat axially symmetric Finslerian space of events, whic…
Physical degrees of freedom in stabilized brane world models
Edward E. Boos, Yuri S. Mikhailov, Mikhail N. Smolyakov +1
We consider brane world models with interbrane separation stabilized by the Goldberger-Wise scalar field. For arbitrary background, or vacuum configurations of the gravitational an…
The background for Cherenkov gluons at RHIC and LHC energies
I. M. Dremin, L. I. Sarycheva, K. Yu. Teplov
The pseudorapidity distribution of centers of dense isolated groups of particles in HIJING model is determined. It can be considered as the background for Cherenkov gluons. If peak…
High energy Cherenkov gluons at RHIC and LHC
I. M. Dremin, L. I. Sarycheva, K. Yu. Teplov
The collective effect of emission by the forward moving partons of high energy Cherenkov gluons in nucleus-nucleus collisions at RHIC and LHC energies is considered. It can reveal…
Search for a Diffuse Flux of High-Energy Extraterrestrial Neutrinos with the NT200 Neutrino Telescope
V. Aynutdinov
We present the results of a search for high energy extraterrestrial neutrinos with the Baikal underwater Cherenkov detector NT200, based on data taken in 1998 - 2002. Upper limits…
Beam-Helicity Asymmetries in Double-Charged-Pion Photoproduction on the Proton
CLAS Collaboration, S. Strauch, B. L. Berman
Beam-helicity asymmetries for the two-pion-photoproduction reaction gamma + p --> p pi+ pi- have been studied for the first time in the resonance region for center-of-mass energies…
The end of the galactic cosmic-ray energy spectrum - a phenomenological view
Joerg R. Hoerandel, N. N. Kalmykov, A. V. Timokhin
Two structures in the all-particle energy spectrum of cosmic rays, the knee at 4 PeV and the second knee around 400 PeV are proposed to be explained by a phenomenological model, th…
Prompt photon hadroproduction at high energies in the k_T-factorization approach
A. V. Lipatov, N. P. Zotov
We consider the prompt photon production at high energy hadron colliders in the framework of k_T-factorization approach. The unintegrated quark and gluon distributions in a proton…
Consistent ADD scenario with stabilized extra dimension
Mikhail N. Smolyakov
A model with one compact extra dimension and a scalar field of Brans-Dicke type in the bulk is discussed. It describes two branes with non-zero tension embedded into the space-time…
A practical criterion of irreducibility of multi--loop Feynman integrals
P. A. Baikov
A practical criterion for the irreducibility (with respect to integration by part identities) of a particular Feynman integral to a given set of integrals is presented. The irreduc…
