A
particle called the neutralino, for instance, is a
type of WIMP that's a perfect candidate for dark matter in part because it doesn't interact with other
particles much, and that would explain why nobody has yet detected it.
Although the LHC will not come anywhere close to detecting strings, it may confirm a precursor theory
called supersymmetry, in which every known
type of particle has a «superpartner»: an unstable, heavier twin.
By arranging their detectors at the edge
of a fusion device, researchers have found that they are able to measure high energy
particles kicked out
of the plasma by a
type of wave that exists in fusion plasmas
called an Alfvén wave (named after their discoverer, the Nobel Prize winner Hannes Alfvén).
Its recommendations include «mount [ing] a massive experiment to search for a hypothesized
type of nuclear decay that is possible only if an elusive, nearly massless
particle called the neutrino is — weirdly — its own antiparticle,» «building a new collider,» and «fully exploit [ing] the three major facilities U.S. nuclear physicists already have.»
The quantities we
call constants
of nature, such as the masses
of elementary
particles, Newton's gravitational constant, and so on, take different values in different bubble
types.
These
particles,
called micelles, are one
type of a class
of materials known as nanoparticles.
So other than
particles of light we
call photons, it's the next most common
type of particle that exists.
Recent modeling along with previously published results from NASA's MESSENGER spacecraft — short for Mercury Surface, Space Environment, Geochemistry and Ranging, a mission that observed Mercury from 2011 to 2015 — has shed new light on how certain
types of comets influence the lopsided bombardment
of Mercury's surface by tiny dust
particles called micrometeoroids.
and one is
called super symmetry; and this is the idea that the two main
types of particles in nature which are basically
particles in matter and
particles of force.
This experiment,
called protoDUNE, is a 1 / 20th scale model
of the planned DUNE neutrino detector, which will study how these elusive
particles oscillate between different
types, or «flavours», and investigate their masses.
The
particle's existence was missed by physicist Hermann Weyl during the initial development
of quantum theory 85 years ago, say the researchers, because it violated a fundamental rule,
called Lorentz symmetry, that does not apply in the materials where the new
type of fermion arises.
There are heavy quarks, in fact a total
of six
types of quarks, and the electrons have
particles that are very similar except they're much heavier,
called muons and tauons.
Previously, all astronomy observations have relied on light — which includes X-rays, radio waves, and other
types of electromagnetic radiation emanating from objects in space — or on very - high - energy
particles called neutrinos and cosmic rays.
This study provides new insights into the evolution and behavior
of a less studied
type of particle,
called «brown carbon.»
Many theories in
particle physics predict the existence
of a so -
called «sterile» neutrino, which would behave differently from the three known
types and, if it exists, could provide a route to understanding the mysterious dark matter that makes up 25 percent
of the universe.
Kok's work, which focused on a
type of airborne
particle called mineral dust, also suggests that there may be several times more dust
particles pumped into the atmosphere than previously believed, since shattered dust appears to produce an unexpectedly high number
of large fragments.
