Consequences of Unusual Behaviour in Einstein's Field Equations for Advanced Propulsion Schemes
Abstract The notion of faster than light travel, passing through parallel universes, or even going back and forth in time is an interesting scientific issue. These activities are examined within Einstein's field equations from an engineering...

Union of Compact Accelerator-Driven Neutron Sources (UCANS) I & II Neutron applications laboratory for ESS-Bilbao
Abstract The ESS-Bilbao Accelerator Center site at Lejoa UPV/EHU campus will be provided with a proton accelerator up to 300-400 MeV. In the first construction phase, a beam extraction will be set at the end of the DTL, which will produce a 50 MeV...

Status of the LEgnaro NeutrOn Source facility (LENOS)
Abstract LENOS is a new facility under development at Laboratori Nazionali di Legnaro (LNL). It is based on a new technic for neutron beam shaping in accelerator based neutron sources. The main advantage of this method is to be able to shape the...

Large volume axionic Swiss cheese inflation
Abstract Continuing with the ideas of (Section 4 of) [A. Misra, P. Shukla, Moduli stabilization, large-volume dS minimum without anti-D3-branes, (non-)supersymmetric black hole attractors and two-parameter Swiss cheese Calabi–Yau's, arXiv: 0707.0105 ...

Modified HPM for solving systems of Volterra integral equations of the second kind
Abstract In this paper, a new reliable technique for solving systems of Volterra integral equations of the second kind has been introduced. This new method is resulted from HPM by a simple modification. This modification is based on the existence of ...

Perturbative and nonperturbative contributions to a simple model for baryogenesis
Abstract Single field baryogenesis, a scenario for Dirac leptogenesis sourced by a time-dependent scalar condensate, is studied on a toy model. We compare the creation of the charge asymmetry by the perturbative decay of the condensate with the...

Analytical evaluation of dimensionally regularized massive on-shell double boxes
Abstract The method of Mellin–Barnes representation is used to calculate dimensionally regularized massive on-shell double box Feynman diagrams contributing to Bhabha scattering at two loops.

Insufficiency of the quantum state for deducing observational probabilities
Abstract It is usually assumed that the quantum state is sufficient for deducing all probabilities for a system. This may be true when there is a single observer, but it is not true in a universe large enough that there are many copies of an...

BPS limit of multi- D- and DF-strings in boundary string field theory
Abstract A BPS limit is systematically derived for straight multi- D- and DF-strings from the D 3 D ¯ ...

BPS-type equations in the non-anticommutative N=2 supersymmetric U(1) gauge theory
Abstract We investigate the equations of motion in the four-dimensional non-anticommutative N=2 supersymmetric U(1) gauge field theory, in the search for BPS configurations. The BPS-like equations, generalizing the Abelian (anti)self-duality...

Skyrmions and pentaquarks in the quark–hadron continuity perspective
Abstract We argue that in the color-flavor-locking (CFL) superconducting phase classical soliton solutions can exist, whose excitations should be interpreted as states formed by a quark (or an antiquark) and condensed diquarks. This finding extends...

Equivalence of the AdS-metric and the QCD running coupling
Abstract We use the functional form of the QCD running coupling to modify the conformal metric in AdS/CFT mapping the fifth-dimensional z-coordinate to the energy scale in the four-dimensional QCD. The resulting type-0 string theory in five...

Relic antineutrino capture on 163Ho decaying nuclei
Abstract The electron capture decay of the isotope 163Ho has been proposed since a long time as a candidate for measuring the electron neutrino mass and recently the interest on this idea has been renewed. In this Letter we note that a direct...

Vacuum energy from an extra dimension with UV/IR connection
Abstract We propose a lower limit on the size of a single discrete gravitational extra dimension in the context of an effective field theory for massive gravitons. The limit arises in this setup from the requirement that the Casimir energy density...

Unified origin of baryons and dark matter
Abstract We investigate the possibility that both the baryon asymmetry of the universe and the observed cold dark matter density are generated by decays of a heavy scalar field which dominates the universe before nucleosynthesis. Since baryons and...
