neutrino

IPA（発音記号）

/njuːˈtɹiːnəʊ/

名詞

An elementary particle that is classified as a lepton, and has an extremely small but nonzero mass and no electric charge. It interacts with the surroundings only via the weak force or gravitation, making it very difficult to detect.

日本語の意味

レプトンに分類される基本粒子の一種で、非常に小さいがゼロではない質量をもち、電荷がなく、主に弱い相互作用や重力を介して他の物質と相互作用するため、検出が極めて困難な粒子

The neutrino passed through the detector and left only the faintest trace, forcing physicists to refine their methods.

ニュートリノが検出器を通過してごくわずかな痕跡しか残さず、物理学者たちは手法を改良することを余儀なくされた。

意味（1）

An elementary particle that is classified as a lepton, and has an extremely small but nonzero mass and no electric charge. It interacts with the surroundings only via the weak force or gravitation, making it very difficult to detect.

But researchers at the CERN lab near Geneva claim they have recorded neutrinos, a type of tiny particle, travelling faster than the barrier of 186,282 miles (299,792 kilometres) per second.
