Was the Orthodox Church in the Rearguard of the February Revolution?
Get PDFThe article evaluates the second edition of M. A. Babkin’s monograph “The Priesthood and the
Kingdom” in the context of numerous reviews of the first edition. Most historians think that
the Russian Orthodox Church was an uncomplaining tool in the hands of the state during the
synodal period. According to Babkin, the leadership of the Orthodox Church was dissatisfied
with its position, was burdened by state control and sought to gain self-government. By
supporting the Provisional Government, the hierarchs hoped to gain new prerogatives, but
they miscalculated. The first edition of monograph caused heated debate. Many reviewers
recognized the conclusions of the author; some objected to certain provisions, the adequacy
of sources and methodology. According to B. N. Mironov, many of Babkin’s findings are
well-reasoned, but he doubts the assessment of the degree of democracy of the hierarchs and
the clergy in general and their ability to influence the course of events. In 1985, Gregory Freeze
challenged the point of view about the Russian Orthodox Church as a servant of the state. In
his opinion, after the reforms of Peter the Great and until 1917, the Church retained the status
of an institution parallel to the state apparatus and firmly defended its prerogatives, remaining
a force to be reckoned with by the authorities. By 1917, the alliance between the throne
and the altar had disintegrated, and the Orthodox Church had become a prominent factor in
the revolution. In fact, Babkin, using other sources and a theological approach, reasonably
supported and developed Freeze’s opinion, which would be correctly called the concept of
Freeze-Babkin

Zimmerman, R. ZwaskaA measurement of charged hadron pair correlations
in two-dimensional η φ space is presented.
The analysis is based on total 30 million central Be + Be
collisions observed in the NA61/SHINE detector at the
CERN SPS for incident beam momenta of 19A, 30A, 40A,
75A, and 150A GeV/c. Measurements were carried out for
unlike-sign and like-sign charge hadron pairs independently.
The C( η, φ) correlation functions were compared with
results from a similar analysis on p + p interactions at similar
beam momenta per nucleon. General trends of the backto-
back correlations are similar in central Be + Be collisions
and p + p interactions, but are suppressed in magnitude
due to the increased combinatorial background. Predictions
from the Epos and UrQMD models are compared
to the measurements. Evolution of an enhancement around
( η, φ) = (0, 0) with incident energy is observed in central
Be + Be collisions. It is not predicted by bothmodels and
almost non-existing in proton–proton collisions at the same
momentum per nucleon
Measurements of production and inelastic cross sections for p+C, p+Be, and p+Al at 60 GeV/c and p+C and p+Be at 120 GeV/c
Get PDFThis paper presents measurements of production cross sections and inelastic cross sections for the
following reactions: 60 GeV=c protons with C, Be, Al targets and 120 GeV=c protons with C and Be
targets. The analysis is performed using the NA61/SHINE spectrometer at the CERN Super Proton
Synchrotron. First measurements are obtained using protons at 120 GeV=c, while the results for protons at
60 GeV=c are compared with previously published measurements. These interaction cross section
measurements are critical inputs for neutrino flux prediction in current and future accelerator-based
long-baseline neutrino experiments.Authors:A. Aduszkiewicz,15 E. V. Andronov,21 T. Antićić,3 V. Babkin,19 M. Baszczyk,13 S. Bhosale,10 A. Blondel,23 M. Bogomilov,2

Isotopic composition of oxygen and hydrogen of ice wedges in Central Yamal
Get PDFNew data on the distribution of the isotopes δ18О and δD of ice wedges in Central Yamal are presented. In the summer of 2019, the massive wedge ice was studied in the thermal circus of the third marine terrace. On the surface of the terrace, polygonal-vein relief is common with a polygon size of about 10–20 m. The largest ice wedge № 1 in the upper part was 1.5 m wide, and its visible depth in the outcrop amounted to 2.3 m. Perpendicular to this wedge, another one № 2 was opened with a width of 60 cm, and 20 m from them the wedge № 3 was opened along the strike. At the level of the head of the wedge № 1, radiocarbon AMS dating was performed based on a sample of host deposits, which showed that the ice in the upper part was about 13 thousand years old (the ice age was of 13.6 cal. BP). According to the isotopic characteristics (average values of δ18О = −24.8, and δD = −187.6 ‰), the ice corresponds to the Yamal ice-wedge ice, which was formed during the MIS‑2 isotopic stage (the end of the Late Pleistocene). The isotopic composition of oxygen indicates temperatures of the cold period of the vein formation from −22.8 to −26.8 °C (on average 7 °C colder than the present-day) and the January temperatures from −34.2 to −40.2 °C (on average 10 °C colder than the present-day). For some ice samples (11 out of 43), high values of deuterium excesses (dexc = 12÷17 ‰) were observed, which is unusual for this type of ice. A few examples of high dexc values of ice wedges are mentioned in the literature for sections of Seyakha yedoma, Cape Sabler and Bolshoi Lyakhovsky Island, and note that for the ice dated to the Late Pleistocene. The deuterium excess values may reflect the unstable climatic conditions of the Late Pleistocene associated with changes in the vapor source and the trajectories of the air masses over the continent

measured at a laboratory beam momentum of 158 GeV/c.
This measurement is the first of its kind in p+p interactions
below LHC energies. It was performed at the CERN SPS by
the NA61/SHINEcollaboration. Double-differential distributions
in rapidity and transverse momentum were obtained
from a sample of 26 × 106 inelastic events. The spectra are
extrapolated to full phase space resulting in mean multiplicity
of (1530)0 (6.73±0.25±0.67)×10−4 and (1530)0
(2.71 ± 0.18 ± 0.18) × 10−4. The rapidity and transverse
momentum spectra and mean multiplicities were compared
to predictions of string-hadronic and statistical model calculations

Super Proton Synchrotron (SPS) studies the onset of deconfinement
in hadron matter by a scan of particle production
in collisions of nuclei with various sizes at a set of energies
covering the SPS energy range. This paper presents results
on inclusive double-differential spectra, transverse momentum
and rapidity distributions and mean multiplicities of π
±,
K±, p and ¯ p produced in the 20% most central 7Be+9Be
collisions at beam momenta of 19A, 30A, 40A, 75A and
150A GeV/c. The energy dependence of the K±/π
± ratios
as well as of inverse slope parameters of the K± transverse
mass distributions are close to those found in inelastic p+p
reactions. The new results are compared to the world data
on p+p and Pb+Pb collisions as well as to predictions of the
Epos, Urqmd, Ampt, Phsd and Smash models

S mesons in inelastic p+p
collisions at beam momentum 158 GeV/c (
√
sNN =
17.3 GeV) was measured with the NA61/SHINE spectrometer
at the CERN Super Proton Synchrotron. Doubledifferential
distributions were obtained in transversemomentum

S was determined
to be 0.162±0.001(stat.)±0.011(sys.). The results
on K0

ZwaskaThe production cross section of 30.92 GeV/c protons on carbon is measured by the NA61/SHINE spectrometer at the CERN Super Proton Synchrotron by means of beam attenuation in a copy (replica) of the 90-cm-long target of the T2K neutrino oscillation experiment. The employed method for direct production cross-section estimation minimizes model corrections for elastic and quasielastic interactions. The obtained production cross section is σprod=227.6±0.8(stat)+1.9−3.2(sys)−0.8(mod) mb. It is in agreement with previous NA61/SHINE results obtained with a thin carbon target, while providing improved precision with a total fractional uncertainty of less than 2%. This direct measurement will reduce the uncertainty of the T2K neutrino flux prediction
