Recent literature on Bohm’s alternative to mainstream quantum mechanics may create the misleading impression that, except for perfunctory dismissals, the theory was ignored by the physics community in the years immediately following its proposal. As a matter of fact, Einstein, Pauli, and Heisenberg all published criticisms of Bohm’s theory, explaining their reasons for not accepting the theory....

The rate at which galaxy halos form is thought to play a key role in explaining many observable cosmological phenomena such as the initial epoch at which luminous matter forms and the distribution of active galaxies. Here we show how Press-Schechter theory[6] can be used to provide a simple, completely analytic model of the halo formation rate. This model shows good agreement with both Monte-Ca...

If neutrino oscillation plays a role in explaining the atmospheric neutrino deficit, then the same phenomenon would necessarily affect also the dark matter indirect-detection signal which consists in a muon-neutrino flux produced by neutralino annihilation in the Earth core. In this paper we investigate to which extent the upgoingmuon signal originated by neutralinos captured inside the Earth w...

Coherent oscillations of a scalar field can mimic the behavior of a perfect fluid with an equation-of-state parameter determined by the properties of the potential, possibly driving accelerated expansion in the early Universe (inflation) and/or in the Universe today (dark energy) or behaving as dark matter. We consider the growth of inhomogeneities in such a field, mapping the problem to that o...

We review the topic of rotation curves of spiral galaxies emphasizing the standard interpretation as evidence for the existence of dark matter halos. Galaxies other than spirals and late-type dwarfs may also possess great amounts of dark matter, and therefore ellipticals, dwarf spirals, lenticulars and polar ring galaxies are also considered. Furthermore, other methods for determining galactic ...

Abstract We review the main experimental evidences on ultra high energy cosmic rays and their implications in physics of these extremely energetic particles, also connection with dark matter cosmology. discuss basis theoretical models aiming at explaining observations, highlighting most relevant open questions this fascinating field research.

We consider the capability of the e+e− linear collider (which is recently called as the International Linear Collider, or ILC) for studying the properties of the heavy Higgs bosons in the supersymmetric standard model. We pay special attention to the large tan β region which is motivated, in particular, by explaining the dark-matter density of the universe (i.e., so-called “rapid-annihilation f...

We propose a new mechanism for explaining the observed asymmetry between matter and antimatter, based on nonperturbative physics at the QCD scale. Our mechanism is a charge separation scenario, making use of domain walls separating the recently discovered long-lived metastable vacua from the lowest energy vacuum. The walls acquire a fractional negative baryon charge, leaving behind a compensati...
