Hyperbolic Inflation in the Light of Planck 2015 data
(APSPhysical Review D, 2015-05-18)
Rubano and Barrow have discussed the emergence of a dark energy, with late-time cosmic acceleration arising from a self-interacting homogeneous scalar field with a potential of hyperbolic power type. Here, we study the ...
Interpreting the CMS l+l-jj missing ET Excess with a Leptoquark Model
(APSPhysical Review D, 2015-06-29)
We present a model of leptoquarks (LQs) with a significant partial branching ratio into an extra sector, taken to be a viable dark matter candidate, other than the canonical lepton and jets final state. For LQs with mass ...
Symmetric polynomials in information theory: entropy and subentropy
(AIP PublishingJournal of Mathematical Physics, 2015-06-12)
Entropy and other fundamental quantities of information theory are customarily
expressed and manipulated as functions of probabilities. Here we study the entropy H
and subentropy Q as functions of the elementary symmetric ...
Anatomy of the ATLAS diboson anomaly
(2015-08-19)
We perform a general analysis of new physics interpretations of the recent ATLAS diboson excesses over Standard Model expectations in LHC Run I collisions. Firstly, we estimate a likelihood function in terms of the truth ...
Singular Inflation
(APSPhysical Review D, 2015-04-08)
We prove that a homogeneous and isotropic universe containing a scalar field with a power-law potential, V(ϕ)=Aϕ^n, with 0<n<1 and A>0 always develops a finite-time singularity at which the Hubble rate and its first ...
New Singularities in Unexpected Places
(World ScientificInternational Journal of Modern Physics D, 2015-09-28)
Spacetime singularities have been discovered which are physically much weaker than those predicted by the classical singularity theorems. Geodesics evolve through them and they only display infinities in the derivatives ...
Twistors and the massive spinning particle
(IOP ScienceJournal of Physics A: Mathematical and Theoretical, 2015-12-07)
Gauge-invariant twistor variables are found for the massive spinning particle with N-extended local worldline supersymmetry, in spacetime dimensions D = 3, 4, 6. The twistor action is manifestly Lorentz invariant but the ...
The synthesis of di-carboxylate esters using continuous flow vortex fluidics
(Royal Society of ChemistryGreen Chemistry, 2015-12-01)
A vortex fluidic device (VFD) is effective in mediating the synthesis of di-esters at room temperature. Processing under ambient conditions allows for a simple and efficient synthesis, whilst operating under continuous ...
Vortices and Monopoles in a Harmonic Trap
(SpringerJournal of High Energy Physics, 2015-12-15)
The Ω-deformation is a harmonic trap, penning certain excitations near the origin in a manner consistent with supersymmetry. Here we explore the dynamics of BPS monopoles and vortices in such a trap. We pay particular ...
Assessment of ice flow dynamics in the zone close to the calving front of Antarctic ice shelves
(International Glaciological SocietyJournal of Glaciology, 2015-12-01)
We investigate the relationship between four ice-shelf characteristics in the area close to the calving front: ice flow speed, strain rate, ice thickness and shelf width. Data are compiled for these glaciological parameters ...
