positive muon
Definition
Noun: A subatomic particle that is the antiparticle of the negative muon. It is a lepton with a positive electric charge and decays into a positron, a neutrino, and an antineutrino.
Usage
The term "positive muon" is used in particle physics to specifically denote the antiparticle form of the muon. It is a fundamental particle. * In experiments, the positive muon is used as a probe to study material properties. * The decay products of a positive muon are a positron and two neutral particles.
Advanced Usage
- Muon Spin Rotation (μSR): A technique where are implanted in a material to act as microscopic magnetic probes, providing information about local magnetic fields.
- The μSR experiment relied on the implantation of positive muons into the superconductor.
Variants and Related Words
- Antimuon: A direct synonym for "positive muon," emphasizing its status as the antiparticle.
- Muon (μ⁻): The more common, negatively charged counterpart of the positive muon.
- Muonium: A quasi-atom consisting of an antimuon (positive muon) and an electron.
- Lepton: The family of elementary particles to which the muon and positive muon belong.
Synonyms
- Antimuon (μ⁺)
Notes on Different Meanings
The term "positive muon" has a single, specific meaning in particle physics. It should not be confused with a general positive charge or other particles. It refers exclusively to the antiparticle of the standard (negative) muon.
Noun
-
the antiparticle of a muon; decays to positron and neutrino and antineutrino
