The humble water gun — the cheap, squirt-squirt variety — has become the weapon of choice and symbol of Spain's anti-tourism protests BARCELONA, Spain -- A group of tourists were sitting at an ...

According to the experiment, the effective electron neutrino mass cannot be more than 0.45 electron volts, which is equivalent to 8×10 -37 kilograms (1.76×10 -36 pounds).

Researchers from the KATRIN (Karlsruhe Tritium Neutrino) experiment report the most precise measurement of the upper mass limit of the neutrino to date, establishing it as 0.45 electron volts (eV ...

To date, neutrino interaction cross sections, which is the probability of a neutrino interacting with a target particle, had not been measured at energies above 300 gigaelectronvolts (GeV) for ...

The IceCube Neutrino Observatory is the 800-pound gorilla of large neutrino experiments. It has about 5,000 sensors that have peered intently at a gigaton of ice under the South Pole for over a ...

Penning-trap measurement of the Q value of electron capture in 163Ho for the determination of the electron neutrino mass. Nat. Phys. (2024).

Neutrinos come in three different types, which physicists call flavors. Each flavor leaves a distinct imprint on a detector like IceCube. When a neutrino bangs into another particle, it usually ...

The electron produced by an electron neutrino collision never decays, and it bangs into every particle in the ice it comes near. This interaction in its wake before the electron finally comes to rest.
