Tetraquark Interpretation of Yb(10753) and Its Production at the LHC
Pleiades Publishing Ltd - Tập 20 - Trang 381-385 - 2023
A structure called
$${{Y}_{b}}(10{\kern 1pt} 753)$$
was observed in the
$${{e}^{ + }}{{e}^{ - }} \to \Upsilon (nS){\kern 1pt} {{\pi }^{ + }}{{\pi }^{ - }}$$
process, where ...... hiện toàn bộ
A hundred years of special theory of relativity
Pleiades Publishing Ltd - Tập 3 - Trang 143-152 - 2006
A special theory of relativity is considered here as an episode of non-Euclidean geometry. Special attention is drawn to the fact that the replacement of the fifth Euclidean postulate by the Lobachevsky postulate of parallel straight lines in the space of velocities of a material point leads to the replacement of the postulate of the same time rate by the postulate of the same velocity of light in...... hiện toàn bộ
Antisymmetrization procedure of identical fermions states
Pleiades Publishing Ltd - Tập 6 - Trang 542-545 - 2009
An efficient procedure for antisymmetrization of an arbitrary system of identical fermions is presented. The approach is based on a simple enumeration scheme for antisymmetric A-particle states and an efficient algorithm for calculation of the coefficients of fractional parentage (CFPs) for a single j-shell with isospin. The developed approach is implemented in a new procedure for the calculation ...... hiện toàn bộ
Modeling of the internal tracking system of the NICA/MPD detector
Pleiades Publishing Ltd - Tập 13 - Trang 483-491 - 2016
The internal tracking system of the NICA/MPD detector is aimed at efficiently detecting the short-lived products of nucleus–nucleus collisions. We consider various geometries of the internal tracking system based on microstrip silicon sensors and simulate its identification power in reconstructing the Λ0 hyperons formed in central Au + Au collisions at

Vacancy Determination in Single-Crystal Diamond Plates Using Positron Annihilation Spectroscopy
Pleiades Publishing Ltd - Tập 20 - Trang 757-762 - 2023
This article presents the results of an investigation into defects in synthetic monocrystalline diamond plates after electron irradiation. Data on defect concentration distribution in the infrared (IR) range are given. In addition to IR spectroscopy, positron annihilation spectroscopy (PAS) is used to study the vacancy defects in diamonds. It is shown that PAS using a monochromatic positron beam c...... hiện toàn bộ
Energy-momentum tensor of areal objects in the Riemannian spacetime
Pleiades Publishing Ltd - Tập 4 - Trang 1-4 - 2007
The energy-momentum tensor of areal objects in the Riemannian world is considered. These objects are called aether fibres and appear as elements—constituents of a specific matter called the aether one.
3D simulation of the ion-beam transport in bending magnets and electrostatic deflectors
Pleiades Publishing Ltd - Tập 13 - Trang 836-841 - 2016
The equations and algorithms for calculating the charged-particle-beam dynamics in bending magnets and electrostatic deflectors, which are used in the ion-beam transport lines and spectrometers, are presented. Calculations of the electromagnetic field 3D maps are illustrated. The value of the electromagnetic-field nonlinearities and their effect on the particle dynamics are analyzed. The simulatio...... hiện toàn bộ
Hard light meson production in (anti)proton-hadron collisions and charge-exchange reactions
Pleiades Publishing Ltd - Tập 12 Số 1 - Trang 1-7 - 2015
Canonical Quantization of a Massive Scalar Field in the Schwarzschild Spacetime
Pleiades Publishing Ltd - Tập 20 - Trang 272-275 - 2023
A consistent procedure of canonical quantization of a massive real scalar field in the Schwarzschild spacetime is carried out. An expansion of the field operator in states that are convenient from a physical point of view is proposed, the fulfillment of all necessary commutation relations is verified, and the Hamiltonian of the system under consideration is obtained explicitly. Some physical conse...... hiện toàn bộ
Study of the dp-elastic scattering at 2 GeV
Pleiades Publishing Ltd - Tập 12 - Trang 695-702 - 2015
The results on the measurements of dp-elastic scattering cross section at the energy 2 GeV at Internal Target Station at the Nuclotron JINR are reported. The data were obtained for the angular range of 70°–107° in the c.m.s. by using CH2 and C targets. The results are compared with the existing data and with the theoretical calculations based on the relativistic multiple scattering theory.
