Accelerating solutions of perfect fluid hydrodynamics for initial energy density and life-time measurements in heavy ion collisions
(Sociedade Brasileira de Física, 2007-06-01)
A new class of accelerating, exact, explicit and simple solutions of relativistic hydrodynamics is presented. Since these new solutions yield a finite rapidity distribution, they lead to an advanced estimate of the initial ...

The interaction of D mesons and nucleons at finite density
(2008-12-01)
We present results on the the influence of changes in the masses and sizes of D mesons and nucleons on elastic DN scattering cross sections and phase shifts in a hadronic medium composed of confined quarks in nucleons. We ...

EXACT AND APPROXIMATE RELATIONS FOR THE SPIN-DEPENDENCE OF THE EXCHANGE ENERGY IN HIGH MAGNETIC FIELDS
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)
The exchange energy of an arbitrary collinear-spin many-body system in an external magnetic field is a functional of the spin-resolved charge and current densities, E(x)[n(up arrow), n(down arrow), j(up arrow), j(down ...
Bounds on the density of sources of ultra-high energy cosmic rays from the Pierre Auger Observatory
(Institute of Physics - IOPBristol, 2013-05)
We derive lower bounds on the density of sources of ultra-high energy cosmic rays from the lack of significant clustering in the arrival directions of the highest energy events detected at the Pierre Auger Observatory. The ...
Friedmann cosmology with decaying vacuum density
(2005)
Among the several proposals to solve the incompatibility between the observed small value of the cosmological constant and the huge value obtained by quantum field theories, we can find the idea of a decaying vacuum energy ...
Changes in irradiance and energy density in relation to different curing distances
(Sociedade Brasileira de Pesquisa Odontológica - SBPqO, 2015)
The present study aimed to assess the influence of curing distance on the loss of irradiance and power density of four curing light devices. The behavior in terms of power density of four different dental curing devices ...
