Towards Predictions of Fission Probabilities for Astrophysics Applications
Abstract In almost all the evaluations of the neutron-induced fission cross section for nuclei involved in nuclear applications, a double- humped fission barrier described by two independent inverted parabolas is considered. In addition, the...

Impact of the three-loop corrections on the QCD analysis of the deep-inelastic scattering data
Abstract We perform the analysis of the existing inclusive deep inelastic scattering (DIS) data within NNLO QCD approximation. The parton distributions functions (PDFs) and the value of strong coupling constant α s(M ...

Uraltsev sum rule in Bakamjian–Thomas quark models
Abstract We show that the sum rule recently proved by Uraltsev in the heavy quark limit of QCD holds in relativistic quark models à la Bakamjian and Thomas, that were already shown to satisfy Isgur–Wise scaling and Bjorken sum rule. This new sum...

Electron screening in d(d,p)t for deuterated metals and the periodic table
Abstract The electron screening effect in the d(d,p)t reaction has been studied for 29 deuterated metals and 5 deuterated insulators/semiconductors. As compared to measurements performed with a gaseous D2 target, a large effect has been observed in...

Probes in fluxbranes and supersymmetry breaking through Hodge-duality
Abstract In this Letter we consider what happens to an M2-brane probe when Minkowski space is dimensionally reduced to a fluxbrane solution of IIA supergravity. Given that fluxbrane reductions generally break supersymmetry, we look at how...

Symplectic geometry, Poincaré algebra, and equal-global time commutators for p-branes in a curved background
Abstract Using a covariant and gauge invariant symplectic structure constructed on the covariant phase space for Dirac–Nambu–Goto p-branes propagating in a curved background, the relevant commutation relations, Poincaré charges, and Poincaré algebra ...

Moduli space and scattering of D0-branes in noncommutative super-Yang–Mills theory
Abstract We study the moduli space of the D0-brane system on Dp-branes realized in the noncommutative super-Yang–Mills theory. By examining the fluctuations around the solitonic solutions generated by solution generating technique, we confirm the...

Observational evidence for axion(-like) particles
Abstract Several unexpected astrophysical observations can be explained by gravitationally captured massive axions or axion-like particles produced inside the Sun or other stars. Their radiative decay in solar outer space would give rise to a...

Effects of random matter density fluctuations on the neutrino oscillation transition probabilities in the Earth
Abstract In this Letter, we investigate the effects of random fluctuations of the Earth matter density for long baselines on the neutrino oscillation transition probabilities. We especially identify relevant parameters characterizing the matter...

Assisted inflation in the Randall–Sundrum scenario
Abstract We extend the Randall–Sundrum (RS) model by adding a fundamental scalar field in the bulk, then study the multi-field assisted inflationary solution on the brane. It is shown that this model not only satisfies observations, but also...

Nature of the scissors mode in nuclei near shell closure: the tellurium isotope chain
Abstract Quasiparticle random-phase approximation calculations, where rotational, translational and Galilean invariance are restored selfconsistently by using separable effective forces, are presented for the ground state dipole response in the...

Calculation of the Higgs boson mass using the complementarity principle
Abstract We compute the Higgs mass in a model for the electroweak interactions based on a confining theory. This model is related to the standard model by the complementarity principle. A dynamical effect due to the large typical scale of the Higgs...

Planck and the local Universe: Quantifying the tension
Abstract We use the latest Planck constraints, and in particular constraints on the derived parameters (Hubble constant and age of the Universe) for the local universe and compare them with local measurements of the same quantities. We propose a way ...

QCD radiative corrections to the soft spectator contribution in the wide angle Compton scattering
Abstract We derive the complete factorization formula for the leading power contribution in wide angle Compton scattering. It consists of the soft- and hard-spectator contributions. The hard-spectator contribution is well known and defined in the...

On the Relaxation of Braided Magnetic Fields
Abstract We discuss the properties of braided magnetic fields, in particular with regard to their relaxation towards equilibrium both in the absence and presence of finite plasma resistivity. We consider a model magnetic field in which a subset of...

Results on Jet Spectra and Structure from ALICE
Abstract Full jet reconstruction in ALICE uses the combined information from charged and neutral particles. Essentially all jet constituents can be measured with large efficiency down to very low transverse momenta ( ...
