Massless Representations of the Poincaré Group: ...
Geometry through its fundamental transformations, the Poincaré group, requires that wavefunctions belong to representations.
(one helicity state), which we will call a KK scalar. The number of helicity states (
degrees of freedom) is conserved in this decomposition. The massless spectrum
is, thus, [g^A^k], (11.14) and its symmetries are the local version of symmetries of
...

Chiral multiplet: A massless complex scalar 0 and a massless chiral spinor X- In
this case the story is analogous. The obtained massless representation has a
spinor and a complex scalar, so it has helicities 0,0 (for scalar) and -1/2,1/2 (for ...

Symmetry Principles Particle Physics
The only known massless particles are the photon and the neutrino and both of
these carry spin angular momentum. The most important feature of massless
particles for the present discussion is the following: a massless particle 'of spin s'
has ...
W. M. Gibson, B. R. Pollard, 1980
Thus for a massless particle, the two definitions would take the form oo x 0, which
is undefined and hence does not actually rule out the existence of particles with
m = 0. Evidently, relativistic mechanics has room for massless particles, always ...

Symmetry and Its Breaking in Quantum Field Theory
Schwinger Model (Massless QED2) QED in four dimensions cannot be solved in
an exact fashion. The simplest system of QED with electrons must be a
positronium which is an electron-positron bound state. However, this bound state
energy ...

College Physics: Reasoning and Relationships
So far, we have assumed cables and ropes are massless, and we justified this
assumption with the claim that the mass of a realistic cable or rope is usually very
small compared with that of other parts of the system. Let's now see how to deal ...

A First Course in String Theory
Therefore, we get a massless scalar field for each direction normal to the Dp-
brane: a D p-brane has a massless scalar for each normal direction. (15.37)
These massless scalars have a physical interpretation. In Section 12.8 we
indicated that ...
