For example,a promising approach to quantization of gravity based on abandoning Lorentz invariance has been proposed by Horava. At low energies Horava gravity reduces to a special case of the so-called Einstein-aether theory - a widely studied phenomenological model, where Lorentz violation is described by a time-like vector field with unit norm (”aether”) that minimally couples to gravity. However a phenomenologically acceptable theory where Lorentz invariance is not fundamental, the latter should appear at low energies as an emergent symmetry. A possible mechanism ensur- ing such emergence is provided by supersymmetry. We consider supersymmetric extension of the Einstein-aether theory. This cannot be realized within the minimal N=1 supergravity which does not allow to define a chiral aether vector superfield. This problem is resolved in the non-minimal formulation of the N=1 supergravity. We use the latter formulation to construct a superfield La- grangian for the aether field coupled to linearized supergravity. We show that the constructed Lagrangian for this model is unique and obtain its bosonic part expanding in the Grassman coordi- nates. The model is considered also at the component level. We study supercurrent supermultiplet in the theory as an alternative way to prove its uniqueness and to construct fermionic interaction in the model. The phenomenological consequences of the model are discussed. Extension tothe full non-linear Einstein-aether supergravity is also briefly outlined.

Time information for the events is seldom not used. In this report we discuss few techniques to use time of event arrival to search for anomalies in events and significantly reduce some systematic er- rors.All techniques are illustrated by real-life application in Troitsk nu-mass ant Tristan in Troitsk experiments.

The tau neutrino interaction cross-section was only measured by the DONUT experiment in 2008 with a large systematical error of 50% due to a poor knowledge of the tau neutrino flux in this beam dump experiment. However, the better measurement of this cross section is needed for the planned future neutrino experiments. It would also allow testing the Lepton Universality (LU) of Standard Model in neutrino interactions. Recently several results for B-meson decays (LHCb, Babar) demonstrated hints of possible LU violation. The tau neutrinos are produced in the Dsme- son decays to tau, Ds -> tau + nu_tau, and the cascade decay of the tau, tau-> x + nu_tau. DsTau experiment has been proposed to study the tau neutrino production at CERN SPS. It will measure the Ds production differential cross-section in proton and tungsten interactions. This will allow reducing of the uncertainty due to the tau neutrino flux in the DONUT result from 50% to 10% .The peculiar Ds cascade decay topology (”double kink”) in a few mm range will be detected by nuclear emulsion tracker thanks to its excellent spatial resolution (˜50nm). In 2016 and 2017, we made test beam exposures of nuclear emulsion modules at CERN SPS 400GeV/c proton beam. A pilot run in August 2018 and physics run in 2021 are scheduled. In this talk, the status and prospects of the DsTau project as well as a review of the modern nuclear emulsion technique and the methods of its data analysis will be presented.

Upper limit could be achieved only if potassium abundance in the Earth exceeds 2%. In Borexino data the valley between beryllium neutrinos and 11C spectrum is filled with betas from 210Bi. But it also contains CNO neutrinos. CNO cycle in the Sun could be depressed according to last researches. This means that part of CNO spectrum could be from terrestrial 40K antineutrinos because their spectra are very similar.

The D-parity of low energy unification schemes gets lifted to a one-parameter subgroup U(1)D of Spin(10). Yet, the choice of the fields signaling spontaneous symmetry breaking leads to disconnected subsets in the vacuum manifold related by the D-parity. The resulting domain walls, existing due to topological reasons but not stable, are identified as topological pseudo-defects. We obtain a class of one-parameter paths connecting D-parity flipped vacua and compute the energy barrier height along the same. We consider the various patterns of symmetry breaking which can result in either intermediate scale gauge groups or a supersymmetric extension of the Standard Model. If the onset of inflation is subsequent to GUT breaking, as could happen also if inflationis naturally explained by the same GUT, the existence of such pseudo-defects can leave signatures in the CMB.

Perturbative convergence is spoled by the presence of these calculations necessitating a difficult all-orders resummation. The integro-differential Banfi-Marchesini-Smye equation, valid in the Large-Nc aproximation and usually solved numerically, provides us with means to account for these logs to all orders at leading-log accuracy. In this talk I present an analytic solution of the BMS equation as a perturbative series in the exponent. This allows us to perform an accurate partial resummation of the large non-global logs in several QCD observables in e+e- annihilation processes as well as hadronic collisions. I also discuss the possible extension of this work to the solution of the Weigert equation which includes finite-Nc corrections and gives more accurate description of the non-global logarithms.
