Possible evidences for cosmological massive neutrinos

Abstract A key question in cosmology is whether massive neutrinos exist on cosmic scales. Current cosmological observations have severely compressed the viable range for neutrino masses and even prefer phenomenologically an effective negative mass. This poses a great challenge to...

Radon-induced backgrounds in the NEXT-100 experiment

A bstract The NEXT-100 detector at the LSC aims at the first competitive search for the 0 νββ decay using a high-pressure 136 Xe electroluminescent time projection chamber. The first low-background run of NEXT-100 at 3.95 bar has been devoted to the measurement of the radon-induc...

Identification of a nanosecond isomer of $$^{164}$$Tb

Abstract This letter reports on the identification of a new isomeric state of $$^{164}$$ 164 Tb ( $$Z=65$$ Z = 65 , $$N=99$$ N = 99 ), which was measured with the DESPEC setup at the GSI Helmholtzzentrum für Schwerionenforschung GmbH following the first relativistic fragmentation...

Zooming in on ‘bi-large’ neutrino mixing with the first JUNO results

Abstract The leptonic mixing matrix is examined within bi-large mixing patterns and confronted with the latest results announced by the Jiangmen Underground Neutrino Observatory (JUNO). We analyze the viability of bi-large mixing schemes and assess JUNO’s ability to test neutrino...

Constraints on Large-Scale White Noise in the Cosmic Density Field

We present observational constraints on large-scale white noise (LSWN) in the cosmic density field, a phenomenon predicted to arise from nonlinear mode coupling during cosmological evolution. Building on the theoretical framework of our companion paper, where we demonstrated that...

Pandemonium free data for the JEFF-project

Abstract Reactor decay heat is due to the decay of both fission products and neutron activated fuel and reactor materials. At relatively short cooling times it is dominated by the beta decay of fission products. The calculation of the decay heat contribution of a particular fissi...

Review of Particle Physics *

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,200 new measurements from 903 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and b...
