Recent works devoted to investigating the role of electric polarizability of nuclei in elastic and nucleosynthesis reactions are critically and constructively reviewed, in order to formulate some problems of the low-energy potential scattering theory. Possible methods for solving these problems are outlined. One of the problems, a correct definition of the range of action of the polarization potential, is discussed in detail. An intuitively clear conception of this radius — the lower bound of the distance range, where the polarization potential may be replaced by identical zero — is used as a starting point. The fact that this bound should be defined in each concrete case is demonstrated by the results obtained by exploration of the pp reaction and the S-wave π±d-elastic collisions. Also discussed are numerical and analytical methods for finding the action radius depending on the studied function, the accuracy required for its evaluation, the scattering energy and the sign of the Coulomb potential.

Abstract In the low energy effective theory of the weak interaction, a macroscopic force arises when pairs of neutrinos are exchanged. We calculate the neutrino Casimir force between plates, allowing for two different mass eigenstates within the loop. We also provide the general potential between point sources. We discuss the possibility of distinguishing whether neutrinos are Majorana or Dirac fermions using these quantum forces.

Great Energy

Forests can be exploited for obtaining biomass, which belongs to a bioenergy group with great energy potential that could replace fossil fuels. This article presents a novel procedure to quantify, map and define biomass, which takes into account both environmental and economic issues. With regard to the environment, only the annual growth of tree species is considered, and not the previous stocks. The growth is determined by logarithmic equations through an original procedure supported by a biomass estimator, which represents the amount of biomass generated annually for energy use, and by means of Excel tables, the exploitable biomass values are obtained. Previously, and by using GIS, areas with slopes exceeding 20% are discarded, thus avoiding soil erosion and damage, and in any case that biomass is not extracted for economic reasons. The same procedure is followed, discarding those areas located more than 4 km from forest roads and runways, as transport costs are increased. Finally, those layers with low energy potential are eliminated as well. Therefore, annually selected quantities of biomass can be obtained safely and abundantly by using detailed distribution maps of the resources, and through planning and performing efficient forestry extraction works.

Sommerfeld Enhancement

We consider main properties of hadronic Dark Matter (DM) candidate consisting of new heavy stable quark and the light ordinary one. This additional quark arises in chiral-symmetric extension of the Standard Model and has standard electromagnetic and strong interactions. Neutral and charged pseudoscalar low-lying states are interpreted as the DM carrier and its nearest charged partner. Their masses and lifetime of the charged state are evaluated; we also describe asymptotics of low-energy potential of the particles interactions with nucleons and each other. Annihilation cross-section is calculated and some peculiarities of Sommerfeld enhancement are analyzed.
