Seeding baryonic dark matter
Domenec Espriu
It has been proposed that primordial quark pellets or PQPs --ultra-dense quark-matter mini- stars-- formed at GeV maybe a good candidate accounting for the dark matter of…
Do primordial quark pellets solve the dark matter puzzle?
Domenec Espriu
We show that primordial quark pellets (PQP), ultra dense quark matter mini-stars formed at around 1 TeV, naturally arise in a radiation dominated universe if rare baryon overdensit…
Impact of on gravitational wave propagation: prospects for the LISA mission
Nil Blanco, Domenec Espriu
It was previously shown that influences gravitational wave propagation beyond simple redshift, by modifying the effective wavenumber. While earlier studies focused on Pulsar…
Weak interactions and the gravitational collapse
Domenec Espriu
The chart of nuclei could be enlarged with a branch describing neutron stars that are huge nuclei of a few solar masses held together by gravity force and sustained by the pressure…
Unitarization of gravity
Iñigo Asiáin, Antonio Dobado, Domènec Espriu
We make use of the improved K-matrix algorithm to obtain unitarized amplitudes in gravity (the so-called Starobisnsky model, of cosmological relevance). The procedure is…
A Tribute to Alexander Andrianov: A Life for Physics
Domenec Espriu
Alexander Andreevich Andrianov was a remarkable personality in Russian physics during the last decades. A member of th prestigious school of theoretical physics in Saint Petersburg…
