This is a review of a two-phase emission detector technology and recent progress in development of experimental programs based on this technology and goaled to search for dark matter, for novel neutrino physics and for double beta-decay. The review is dedicated to the 90th anniversary of the outstanding experimental physicist Boris Anatolyevich Dolgoshein, in whose laboratory exactly 50 years...
Recent astronomical data on Black hole observations are reviewed. The arguments in favor that the observed black holes are predominantly primordial (PBH) are presented. The mass spectrum of PBH is best fit to the log-normal one. A model of PBH formation with log-narmal spectrum is briefly described.
The first direct detection of gravitational waves from the binary collision of two black holes and the first detection of gravitational waves from GW170817, a binary neutron star merger in association with its electromagnetic counterpart, launched the new era of gravitational-wave astronomy. Two years after GW170817, the LIGO-Virgo collaboration continues to mesmerize the physics community...
The discovery of neutrino oscillations and neutrino mass opens a new area in particle physics, astroparticle physics, and cosmology by studying neutrinos. The long-baseline neutrino oscillation experiments are essential to explore the properties of neutrinos.
Today, we are focusing to measure neutrino oscillations more precisely and to search for CP violation in neutrinos.
I will review the...
I review the experimental indications in favor of short-baseline neutrino oscillations and discuss their interpretation in the framework of 3+1 neutrino mixing with a sterile neutrino at the eV scale.
I discuss the recent results of short-baseline reactor neutrino experiments and their statistical analyses.
I discuss the compatibility of the LSND and MiniBooNE results and possible solutions of...
This talk will be centered on the description of the first detection of solar neutrinos from the CNO cycle with Borexino.
Borexino is running at the “Laboratori del Gran Sasso” in Italy since 2007. Its major distinctive feature is the unprecedented ultralow background of the inner scintillating core, which is the foundation of the outstanding results it has accumulated over the years.
After...
he observation of neutrinoless double beta ($0\nu\beta\beta$) decay would establish the Majorana nature of neutrinos and explicitly show that lepton number conservation is violated. In their search for the rare decay in the isotope $^{76}$Ge, the {\sc Gerda} and {\sc Majorana Demonstrator} (MJD) experiments have achieved the lowest backgrounds and the best energy resolution in the signal...
Hyper-Kamiokande is a next generation large-scale water Cherenkov detector. Its fiducial mass will be about an order of magnitude larger than Super-Kamiokande and the detector performance is significantly improved with newly developed photo-sensors. Combination of the Hyper-Kamiokande detector with the upgraded J-PARC neutrino beam will provide unprecedented high statistics of the neutrino and...
In direct searches for Dark Matter (DM) a technology developing by EDELWEISS experiment is arrays of Ge mono-crystal detectors operated at a temperature of few mK and equipped with electrodes and thermal sensors. Applying a small (few V/cm) external field, a simultaneous measurement of ionization and heat signals allows efficient identification of nuclear and electron recoils. A larger bias...
I'll present a summary of techniques used to measure ultra-high energy neutrinos by both ice-based and mid-latitude experiments. I'll also give comments on multi-messenger aspects of these physics programs, and attempt to outline plans for the next-generation radio neutrino experiment (IceCube Gen-2 radio) planned to begin construction at South Pole in 2025.
