269. Results and simulation of the prototype detection unit of KM3NeT-ARCA

Christophe Maurice Ferdinand Hugon (GE)

KM3NeT-ARCA is the successor of the ANTARES Mediterranean neutrino telescope. It is a km3 detector using a new design for the light detection units: the digital optical module. These optical modules were developed by the KM3NeT Collaboration to improve the detection capability of neutrino interactions in the fiducial volume thanks to their large total photocathode area, summed on the 31 three...

101. Search for high energy neutrinos from bright GRBs with ANTARES

Matteo Sanguineti (GE)

The ANTARES telescope is currently the largest neutrino detector of the Northern Hemisphere, fully operational since 2008. The search for high-energy neutrinos from astrophysical sources is one of the main purposes of the ANTARES scientific project; among them gamma-ray bursts are thought to be site of hadronic acceleration, thus neutrinos are expected from the decay of charged mesons,...

98. Baikal-GVD

Dr. Olga Suvorova (INR RAS)

We present the status of newly constructed cluster of the Gigaton Volume Detector in Lake Baikal (Baikal-GVD) designed for registration of very high energy neutrinos of astrophysical origin. This “Dubna” cluster has been upgraded to its baseline configuration, with 288 optical modules (OMs) arranged on eight vertical strings. Thus the instrumented water volume has been gotten up to about 5.9...

107. Juno

The JUNO Jiangmen Underground Neutrino Observatory, a 20 kton multi-purpose underground liquid scintillator detector, has been proposed and approved for realization in the south of China. After an intense design phase, the overall concept of the structure of the detector has been finalized, paving the way towards the construction of the several components and subsystems, which will compose it....

108. The Luna experiment

The thermo-nuclear reactions responsible for the luminosity and for the chemical evolution of stars take place in a narrow energy window: the Gamow peak. The extremely low value of the cross section inside the Gamow peak has always prevented its direct measurement in a laboratory at the surface of the Earth, where the signal to background ratio is too small mainly because of cosmic ray...

251. Underground Study of Big Bang Nucleosynthesis in the Precision Era of Cosmology

Carlo Gustavino (ROMA1)

14/05/09, 19:05

Big Bang Nucleosynthesis (BBN) is the first probe of cosmology and particle physics. Assuming Standard model of cosmology and particle physics , light elements such as deuterium, helium and lithium were produced in the first minutes of cosmic time. The amount of each primordial nuclide depends on the expansion rate of the Universe and on the baryon density . The expansion rate is governed by...

234. A few eV sterile neutrino as partial dark matter

Prof. subinoy das (IIA, Abangalore)

14/05/09, 19:30

Recent short baseline experiments (MiniBooNE and LSND) as well as reactor experiments (Daya bay and T2K) might be hinting for an extra eV scale light sterile neutrino state. But these results are in tension with the recent Planck data as it does not allow an extra thermalized neutrino. To alleviate this conflict, we propose a scenario where the light sterile neutrino is in thermal equilibrium...
