In summary, neutrinos are fundamental particles with little mass and no electric charge that constantly move through space. Left-handed and right-handed neutrinos refer to the direction of their spin, and the existence of right-handed neutrinos could help explain phenomena such as neutrino oscillation and the matter-antimatter asymmetry in the universe. Scientists detect neutrinos using large detectors and while there is no direct evidence, there is evidence from various experiments that suggest the existence of right-handed neutrinos.

The new fermilab video ends with a teaser: Do right-handed neutrinos exist or is it that they do not interact with matter? (at 7:30) For those of us who cannot wait for the next video to find out, is there a clear answer?

Most likely there is, but we do not know what it is.

How would you know if there were?
 

Related to Are there right handed neutrinos?

1. What are neutrinos?

Neutrinos are fundamental particles that are electrically neutral and have very little mass. They are one of the building blocks of the universe and are constantly moving through space.

2. What is the difference between left-handed and right-handed neutrinos?

Left-handed and right-handed neutrinos refer to the direction of the spin of the neutrino. Left-handed neutrinos have their spin pointing in the opposite direction of their motion, while right-handed neutrinos have their spin pointing in the same direction as their motion.

3. Why is the existence of right-handed neutrinos important?

The existence of right-handed neutrinos is important because it would help explain the phenomenon of neutrino oscillation, where neutrinos change from one type to another. It could also potentially help explain the matter-antimatter asymmetry in the universe.

4. How do scientists detect neutrinos?

Scientists use large detectors, such as massive underground tanks or detectors buried deep underground, to detect neutrinos. These detectors are designed to capture the rare interactions between neutrinos and other particles.

5. Is there evidence for the existence of right-handed neutrinos?

While there is no direct evidence for the existence of right-handed neutrinos, there is evidence from various experiments that suggest that they may exist. Further research and experiments are needed to confirm their existence.
