SU(3) c color transformations correspond to "rotations" in color space (which, mathematically speaking, is a complex space). Every quark flavor f , each with subtypes f B , f G , f R corresponding to the quark colors, [ 79 ] forms a triplet: a three-component quantum field that transforms under the fundamental representation of SU(3) c .

Alternatively, a proton can hit oxygen-16, yielding two protons, a neutron, and again an alpha particle and a beryllium-10 nucleus. Boron can also be created directly. The beryllium and boron are brought down to the ground by rain. [2] See Cosmogenic nuclide for a list of nuclides produced by cosmic ray spallation.
A related classification though not a binary system is optical binary, which refers to objects that are so close together in the sky that they appear to be a binary system, but are not. Such objects merely appear to be close together, but lie at different distances from the Solar System. [3] [4]
The process inverse to particle annihilation can be called matter creation; more precisely, we are considering here the process obtained under time reversal of the annihilation process. This process is also known as pair production , and can be described as the conversion of light particles (i.e., photons) into one or more massive particles .
Diagram showing how the polarity of the QRS complex in leads I, II, and III can be used to estimate the heart's electrical axis in the frontal plane. The QRS complex is the combination of three of the graphical deflections seen on a typical electrocardiogram (ECG or EKG). It is usually the central and most visually obvious part of the tracing.
Matter in the solid state maintains a fixed volume (assuming no change in temperature or air pressure) and shape, with component particles (atoms, molecules or ions) close together and fixed into place. Matter in the liquid state maintains a fixed volume (assuming no change in temperature or air pressure), but has a variable shape that adapts ...
A well known example of a two-state system is the spin of a spin-1/2 particle such as an electron, whose spin can have values +ħ/2 or −ħ/2, where ħ is the reduced Planck constant. The two-state system cannot be used as a description of absorption or decay, because such processes require coupling to a continuum.
Detailed measurements show that this liquid is a quark–gluon plasma where quarks, antiquarks and gluons flow independently. [ 34 ] Schematic representation of the interaction region formed in the first moments after the collision of heavy ions with high energies in the accelerator.
