    Atom-optics hologram in the time domain

    Full text link
    The temporal evolution of an atomic wave packet interacting with object and reference electromagnetic waves is investigated beyond the weak perturbation of the initial state. It is shown that the diffraction of an ultracold atomic beam by the inhomogeneous laser field can be interpreted as if the beam passes through a three-dimensional hologram, whose thickness is proportional to the interaction time. It is found that the diffraction efficiency of such a hologram may reach 100% and is determined by the duration of laser pulses. On this basis a method for reconstruction of the object image with matter waves is offered.Comment: RevTeX, 13 pages, 8 figures; minor grammatical change

    QED Radiative Corrections in Processes of Exclusive Pion Electroproduction

    Get PDF
    Formalism for radiative correction (RC) calculation in exclusive pion electroproduction on the proton is presented. A FORTRAN code EXCLURAD is developed for the RC procedure. The numerical analysis is done in the kinematics of current Jefferson Lab experiments.Comment: 13 pages, 9 figures; requires RevTeX

    One-loop corrections to the Drell--Yan process in SANC (II). The neutral current case

    Full text link
    Radiative corrections to the neutral current Drell--Yan-like processes are considered. Complete one-loop electroweak corrections are calculated within the SANC system. Theoretical uncertainties are discussed. Numerical results are presented for typical conditions of LHC experiments.Comment: 17 pages, 9 figures, 3 table

    Изучено влияние гипероксии на фагоцитарную активность и состояние интерфазного хроматина нейтрофилов. Установлено, что использование гипероксических ингаляционных смесей при проведении лапароскопических операций вызывает снижение фагоцитарной активности нейтрофилов периферической крови, компактизацию эухроматина и разрыхление гетеро– и перигранулярного хроматина нейтрофилов.The effect of hyperoxia on the phagocytic activity and the state of the interphase chromatin of neutro-phils was studied. It was found that the use of inhaled hyperoxic mixtures during laparoscopic surgery causes a decrease in the phagocytic activity of peripheral blood neutrophils, compaction of the euchroma-tin and loosening of the heterochromatin of neutrophils
