Numerical Study of a Multi-stage Dielectric Laser-driven Accelerator
Abstract In order to overcome the limits of commonly used radiofrequency accelerators, it is highly desirable to reduce the unit cost and increase the maximum achievable accelerating gradient. Dielectric laser-driven accelerators (DLAs) based on...

Electroweak instantons/sphalerons at VLHC?
Abstract There is a close analogy between electroweak instanton-induced baryon plus lepton number (B+L) violating processes in Quantum Flavor Dynamics (QFD) and hard QCD instanton-induced chirality violating processes in deep-inelastic scattering....

On plasma oscillations in strong electric fields
Abstract We describe the creation and evolution of electron–positron pairs in a strong electric field as well as the pairs annihilation into photons. The formalism is based on generalized Vlasov equations, which are numerically integrated. We...

Neutrino masses in theories with dynamical electroweak symmetry breaking
Abstract We address the problem of accounting for light neutrino masses in theories with dynamical electroweak symmetry breaking. We discuss this in the context of a class of (extended) technicolor (ETC) models and analyze the full set of Dirac and...

Bi-large neutrino mixing from bilinear R-parity violation with non-universality
Abstract We investigate how the bi-large mixing required by the recent neutrino data can be accommodated in the supersymmetric standard model allowing bilinear R-parity violation and non-universal soft terms. In this scheme, the tree-level...

Gravitino problem in supergravity chaotic inflation and SUSY breaking scale after BICEP2
Abstract Gravitinos are generically produced by inflaton decays, which place tight constraints on inflation models as well as supersymmetry breaking scale. We revisit the gravitino production from decays of the inflaton and the supersymmetry...

Production of medical radionuclides in Russia: Status and future—a review
Abstract We present a review of reactor and accelerator centers in Russia that produce medical isotopes, the majority of which are exported. In the near future, we anticipate increased isotope production for use in nuclear medicine in Russia. The...

3.55 keV X-ray line signal from excited dark matter in radiative neutrino model
Abstract We study an exciting dark matter scenario in a radiative neutrino model to explain the X-ray line signal at 3.55 keV recently reported by XMN-Newton X-ray observatory...

Ward–Green–Takahashi identities and the axial-vector vertex
Abstract The colour-singlet axial-vector vertex plays a pivotal role in understanding dynamical chiral symmetry breaking and numerous hadronic weak interactions, yet scant model-independent information is available. We therefore use longitudinal and ...

On the limitations of linear growth rates in triply diffusive convection in porous medium
Abstract The present paper purports to deal with the problem of triply diffusive convection in sparsely distributed porous medium using the Darcy-Brinkman model. Bounds are derived for the modulus of the complex growth rate p of an arbitrary...

Non-perturbative Nekrasov partition function from string theory
Abstract We calculate gauge instanton corrections to a class of higher derivative string effective couplings introduced in [1]. We work in Type I string theory compactified on K3 ...

Universe without expansion
Abstract We discuss a cosmological model where the universe shrinks rather than expands during the radiation and matter dominated periods. Instead, the Planck mass and all particle masses grow exponentially, with the size of atoms shrinking...

Scattering amplitudes with off-shell quarks
Abstract We present a prescription to calculate manifestly gauge invariant tree-level scattering amplitudes for arbitrary scattering processes with off-shell initial-state quarks within the kinematics of high-energy scattering. ...

COMPASS experiment at CERN: hadron spectroscopy and open charm results
Abstract COmmon Muon and Proton Apparatus for Structure and Spectroscopy (COMPASS) is a fixed target experiment at CERN dedicated to studies of the spin structure of the nucleon and of the spectroscopy of hadrons. During the years 2002–2004 and...
