Three-body breakup within the fully discretized Faddeev equations
A novel approach is developed to find the three-body breakup amplitudes and
cross sections within the modified Faddeev equation framework. The method is
based on the lattice-like discretization of the three-body continuum with a
three-body stationary wave-packet basis in momentum space. The approach makes
it possible to simplify drastically all the three- and few-body breakup
calculations due to discrete wave-packet representations for the few-body
continuum and simultaneous lattice representation for all the scattering
operators entering the integral equation kernels. As a result, the few-body
breakup can be treated as a particular case of multi-channel scattering in
which part of the channels represents the true few-body continuum states. As an
illustration for the novel approach, an accurate calculations for the
three-body breakup process with non-local and local
interactions are calculated. The results obtained reproduce nicely the
benchmark calculation results using the traditional Faddeev scheme which
requires much more tedious and time-consuming calculations.Comment: 17 pages, 13 figure
Inclusive probability to record an electron in elastic electromagnetic scattering by a spin one-half hadron wave packet
The inclusive probability to record an electron in elastic electromagnetic
scattering of an electron by a spin one-half hadron is obtained, the initial
quantum states of the electron and the hadron being described by the density
matrices of a general form. Contrary to the Rosenbluth formula for the
differential cross-section for this process, the first nontrivial contribution
to the inclusive probability turns out to be of order and not
. This contribution describes the interference between the trivial
contribution to the -matrix and the leading contribution to its connected
part. The explicit expression for this interference terms is derived. It is
shown that the same interference term arises when the electron is scattered by
the classical electromagnetic field produced by the hadron electromagnetic
current averaged with respect to the free evolving density matrix of the
hadron, even in the case of a single hadron. The interference term describes
coherent scattering of the electron by the hadron wave packet and is immune to
the quantum recoil experienced by a hadron due to scattering. The effective
electron mass operator is found on the mass-shell.Comment: 14 pp., 2 fig
Legal Liability for the Violation of Traffic Rules by a Person Subjected to an Administrative Penalty
In the article actual problems of qualification of repeated driving of a car, a tram or other mechanical vehicle by a person in the state of intoxication are considered (Article 264.1 of the Criminal Code of the Russian Federation). Ways to solve these problems are suggested. The problems of establishing administrative prejudice in criminal legislation are identified, taking into account the provisions of the decision of the Constitutional Court of the Russian Federation of February 10, 2017 no. 2-P. The problems of qualification of repeated driving of a vehicle by a person in the state of intoxication are investigated. It is substantiated that Art. 264.1 of the Criminal Code of the Russian Federation is a norm with double prevention. The conclusion is made that it is necessary to adopt a resolution of the Plenum of the Supreme Court of the Russian Federation where an interpretation will be given of the application of norms with administrative prejudice to develop a unified approach to understanding the criminalization of such acts and the grounds for prosecuting those who committed them
Formação da teoria verbocêntrica da sentença no final do século XIX - segundo terço do século XX
The development of some provisions of the verbocentric theory of sentence covers the article. The interdisciplinary nature of the theory is proved, since it is realized at the intersection of lexicology, semantics, morphology, word formation and syntax. The provisions of the verbocentric theory in the works of Russian and foreign scientists of the late XIX - second third of the XX century are analyzed. The main approaches to determining the role of the Russian verb in the structure of the sentence are revealed. According to the first approach, the subject is the top of the sentence. According to the second approach, the subject and predicate are equal members of the sentence. According to the third approach, there is no equality between the subject and the predicate, since the verb in the sentence occupies a dominant position.El desarrollo de algunas disposiciones de la teorÃa verbocéntrica de la oración cubre el artÃculo. La naturaleza interdisciplinaria de la teorÃa está demostrada, ya que se realiza en la intersección de lexicologÃa, semántica, morfologÃa, formación de palabras y sintaxis. Se analizan las disposiciones de la teorÃa verbocéntrica en los trabajos de cientÃficos rusos y extranjeros de finales del siglo XIX - segundo tercio del siglo XX. Se revelan los principales enfoques para determinar el papel del verbo ruso en la estructura de la oración. Según el primer enfoque, el sujeto es la parte superior de la oración. De acuerdo con el segundo enfoque, el sujeto y el predicado son miembros iguales de la oración. Según el tercer enfoque, no hay igualdad entre el sujeto y el predicado, ya que el verbo en la oración ocupa una posición dominante.O desenvolvimento de algumas disposições da teoria verbocêntrica da sentença abrange o artigo.
