New Superpotential in Conservation Laws in General Relativity
J. Adamek, J. Novotny
This work refers to the new formula for the superpotential Uikl in conservation laws in general relativity satisfying the integral and differential conservation laws within the Sch…
The High-Acceptance Dielectron Spectrometer HADES
The HADES Collaboration, G. Agakishiev, A. Balanda +110
HADES is a versatile magnetic spectrometer aimed at studying dielectron production in pion, proton and heavy-ion induced collisions. Its main features include a ring imaging gas Ch…
Dielectron production in 12C+12C collisions at 2 AGeV with HADES
Piotr Salabura
The invariant-mass spectrum of pairs produced in C+C collisions at an incident energy of 2 GeV per nucleon has been measured for the first time. The measure…
Einstein-Maxwell fields generated from the gamma-metric and their limits
L. Richterek, J. Novotny, J. Horsky
Two solutions of the coupled Einstein-Maxwell field equations are found by means of the Horsky-Mitskievitch generating conjecture. The vacuum limit of those obtained classes of spa…
New Einstein-Maxwell fields of Levi-Civita's type
L. Richterek, J. Novotny, J. Horsky
The method based on the Horsky-Mitskievitch conjecture is applied to the Levi-Civita vacuum metric. It is shown, that every Killing vector is connected with a particular class of E…
