Massless in a sentence

Additionally, it can be shown that any massless spin-2 field would give rise to a force indistinguishable from gravitation, because a massless spin-2 field would couple to the stress–energy tensor in the same way that gravitational interactions do.

Neutrinos are virtually massless, subatomic particles which race across the universe, passing unnoticed through planets and stars.

Although the galactic vector potential is very large because the galactic magnetic field exists on very great length scales, only the magnetic field would be observable if the photon is massless.

For collapsible Particle physics (also high energy physics) is the branch of physics that studies the nature of the particles that constitute matter (particles with mass ) and radiation (massless particles).

From cosmological arguments, relic background neutrinos are estimated to have density of 56 of each type per cubic centimeter and temperature main (main) if they are massless, much colder if their mass exceeds main.

If the initial displacement is A, and there is no initial velocity, the solution of this equation is given by: : Given an ideal massless spring, is the mass on the end of the spring.

If their current quarks were massless particles, it could make the chiral symmetry exact and thus the Goldstone theorem would dictate that all pions have a zero mass.

In 1974, Tamiaki Yoneya discovered that all the known string theories included a massless spin-two particle that obeyed the correct Ward identities to be a graviton.

Incidentally, this rejection of the hypothesis of a massless photon enabled him to doubt the hypothesis of the expansion of the universe.

In the massless limit, it means that only one of two possible chiralities is observed for either particle.

It is also based on the assumption that the points at both ends are massless, as in the case when transferring between two orbits around Earth for instance.

Massless virtual gluons compose the numerical majority of particles inside hadrons.

Mathematically, fermions come in three types - Weyl fermions (massless), Dirac fermions (massive), and Majorana fermions (each its own antiparticle).

Tension Tension forces can be modeled using ideal strings that are massless, frictionless, unbreakable, and unstretchable.

That a photon is not quite massless is imposed by the coherence of his theory.

The approximate flavor symmetries do have associated gauge bosons, observed particles like the rho and the omega, but these particles are nothing like the gluons and they are not massless.

The electron is thus relatively massless compared with the muon, and thus the electronic mode is almost prohibited.

The problem of a material object exceeding light speed is that an infinitely increasing amount of kinetic energy is required to attempt moving as fast as a massless photon.

There are other possibilities in which neutrino can oscillate even if they are massless.

The rest mass of a proton is, thus, the invariant mass of the system of moving quarks and gluons that make up the particle, and, in such systems, even the energy of massless particles is still measured as part of the rest mass of the system.
