The chiral symmetry transformation can be divided into a component that treats the left-handed and the right-handed parts equally, known as vector symmetry, and a component that actually treats them differently, known as axial symmetry. [2] (cf. Current algebra.) A scalar field model encoding chiral symmetry and its breaking is the chiral model.
In physics, chirality may be found in the spin of a particle, where the handedness of the object is determined by the direction in which the particle spins. [4] Not to be confused with helicity, which is the projection of the spin along the linear momentum of a subatomic particle, chirality is an intrinsic quantum mechanical property, like spin.
In this case a new Majorana mass term is added to the Yukawa sector: = (¯ + ¯) where C denotes a charge conjugated (i.e. anti-) particle, and the terms are consistently all left (or all right) chirality (note that a left-chirality projection of an antiparticle is a right-handed field; care must be taken here due to different notations ...
Helicity is a pseudo-scalar quantity: it changes sign under change from a right-handed to a left-handed frame of reference; it can be considered as a measure of the handedness (or chirality) of the flow. Helicity is one of the four known integral invariants of the Euler equations; the other three are energy, momentum and angular momentum.
An object that is not chiral is said to be achiral. A chiral object and its mirror image are said to be enantiomorphs. The word chirality is derived from the Greek χείρ (cheir), the hand, the most familiar chiral object; the word enantiomorph stems from the Greek ἐναντίος (enantios) 'opposite' + μορφή (morphe) 'form'.
Dextrorotation and laevorotation (also spelled levorotation) [1] [2] in chemistry and physics are the optical rotation of plane-polarized light.From the point of view of the observer, dextrorotation refers to clockwise or right-handed rotation, and laevorotation refers to counterclockwise or left-handed rotation.
“Here is a useful formula for determining how many to keep: (Number of people who use mug/water bottle ) × (number of mugs they use a day) then X that by (one + the number of days between ...
The principal chiral model is defined by the Lagrangian density = = (), where is a dimensionless coupling. In differential-geometric language, the field U {\displaystyle U} is a section of a principal bundle π : P → M {\displaystyle \pi :P\rightarrow M} with fibres isomorphic to the principal homogeneous space for M (hence why this defines ...
