The study of neutron stars is a topic of central interest in the investigation of the properties of strongly compressed hadronic matter. Whereas in heavy-ion collisions the fireball, created in the co...
We study the hybrid inflationary potential in a regime where the defect field is light, and more than 60 e-folds of accelerated expansion occur after the symmetry breaking transition. Using analytic a...
Hybrid stars with the Dyson-Schwinger quark model
Hybrid stars Dyson-Schwinger quark model
2011/10/18
We study the hadron-quark phase transition in the interior of neutron stars. For the hadronic sector we use a microscopic equation of state involving nucleons and hyperons derived within the Brueckner...
Primordial black hole formation and hybrid inflation
Primordial formation hybrid inflation
2011/9/29
We calculate the contribution to the curvature perturbation, that is generated while the waterfall field grows exponentially (which can occur only if the waterfall field mass is $m\gg H$). We consider...
The exposure of the hybrid detector of the Pierre Auger Observatory
the hybrid detector the Pierre Auger Observatory
2011/1/13
The Pierre Auger Observatory is a detector for ultra-high energy cosmic rays. It consists of a surface array to measure secondary particles at ground level and a fluorescence detector to measure the d...
In this paper we investigate the thermal evolution of hybrid stars, objects composed of a quark
matter core, enveloped by ordinary hadronic matter. Our purpose in this paper is to investigate
how im...
Waterfall field in hybrid inflation and curvature perturbation
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/6
We study carefully the contribution of the waterfall field to the curvature perturbation at the end of hybrid inflation. In particular we clarify the parameter dependence analytically under reasonable...
Hadronic- and electromagnetic cores of air-showers observed by hybrid experiments at high mountains
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/4
Characteristics of the high energy families (bundle of high energy e, gamma) and hadrons in the air-showers detected in the hybrid experiment together with emulsion chamber and AS-array at Mt.Chacalta...

A heliospheric hybrid model：hydrodynamic plasma flow and kinetic cosmic ray transport
heliospheric hybrid hydrodynamic plasma flow kinetic cosmic ray transport
2009/5/27
In this paper we present a new five particle species hybrid model for calculating cosmic ray particle transport and acceleration in a dynamic heliospheric environment. In particular the effects of sol...
