Enhancement of the transverse non-reciprocal magneto-optical effect
The origin and properties of the transverse non-reciprocal magneto-optical
(nMO) effect were studied. The transverse nMO effect occurs in the case when
light propagates perpendicularly to the magnetic field. It was demonstrated
that light can experience the transverse nMO effect only when it propagates in
the vicinity of a boundary between two materials and the optical field at least
in one material is evanescent. The transverse nMO effect is pronounced in the
cases of surface plasmons and waveguiding modes. The magnitude of the
transverse nMO effect is comparable to or greater than the magnitude of the
longitudinal nMO effect. In the case of surface plasmons propagating at a
boundary between the transition metal and the dielectric it is possible to
magnify the transverse nMO effect and the magneto-optical figure-of-merit may
increase from a few percents to above 100%. The scalar dispersion relation,
which describes the transverse MO effect in cases of waveguide modes and
surface plasmons propagating in a multilayer MO slab, was derived
Measurement of hadron cross sections with the SND detector
New results on exclusive hadron production in annihilation obtained
in experiments with the SND detector at the VEPP-2M and VEPP-2000
colliders are presented.Comment: 4 pages, 4 figures, presented at the 14th International Workshop on
Meson Production, Properties and Interaction (MESON 2016), Cracow, Poland,

Study of the process with SND detector at the VEPP-2M collider
In experiment with the SND detector at VEPP-2M collider the
cross section was measured in the energy range
=0.60--1.38 GeV with the integrated luminosity of 27.8 pb. The
measured cross section is well described by the vector meson dominance model
with contributions from the , , ,
resonances and agrees with results of previous
measurements. The decay probabilities \BR(\phi\to\eta\gamma),
\BR(\omega\to\eta\gamma) and \BR(\rho\to\eta\gamma) were measured with the
accuracies better than or comparable to the world averages.Comment: 13 pages, 6 figures, 5 table
Hadron Production via e+e- Collisions with Initial State Radiation
A novel method of studying e+e- annihilation into hadrons using initial state
radiation at e+e- colliders is described. After brief history of the method,
its theoretical foundations are considered. Numerous experiments in which
exclusive cross sections of e+e- annihilation into hadrons below the
center-of-mass energy of 5 GeV have been measured are presented. Some
applications of the results obtained to fundamental tests of the Standard Model
are listed.Comment: 50 pages, 88 figures, accepted for publication in Rev. Mod. Phy
