Which fundamental force acts on neutrinos?
PhysicsParticle astronomy
Quick Answer
Neutrinos interact primarily through the weak force. They almost never interact with matter because the weak force is so short-ranged.
The Full Story
Neutrinos are famously difficult to detect because they interact only weakly and do not feel the electromagnetic force. They pass through Earth in enormous numbers with little effect. Detectors such as Super-Kamiokande in Japan and IceCube at the South Pole are built to catch the rare interactions that do occur. The weak force is responsible for these interactions and for many neutrino-producing processes in stars and reactors. Neutrino studies have transformed particle physics since the 20th century.
Key Facts
1.Neutrinos interact mainly via the weak force
2.Most neutrinos pass through matter unhindered
3.Super-Kamiokande began operation in 1996
