1Actually the chiral symmetry breaking of QCD also breaks electroweak SU(2) U(1). The e ect of this gauge symmetry breaking, however, is obscured by the much larger breaking associated with the Higgs eld condensation. 2Actually unbroken gauge symmetry does not necessarily imply massless vector bosons, as we learn from QCD.

Energy must be added to separate the particles sufficiently far apart, thus breaking the bonds. Since the maximum value of the bond energy occurs when the particles are widely separated, and because of the way the pair-wise potential is defined, the bond energy of liquids and solids must be less than zero; that is, the bond energy is negative.

Hadrons and Leptons. Particles can also be revealingly grouped according to what forces they feel between them. All particles (even those that are massless) are affected by gravity, since gravity affects the space and time in which particles exist.
Particle accelerator . A particle accelerator works the same way, except that they are much bigger, the particles move much faster (near the speed of light) and the collision results in more subatomic particles and various types of nuclear radiation.Particles are accelerated by electromagnetic waves inside the device, in much the same way as a surfer gets pushed along …

No headers Figure 5.9: Maximum crest angle.. Section 5.2.2 demonstrated how shoaling would increase the wave height until infinity, at least in the absence of a physical limit to the steepness of waves. A wave crest becomes unstable and starts breaking when the particle velocity exceeds the velocity of the wave crest (the wave celerity).
Direct numerical simulations of breaking focused wave groups show a linear scaling of the net particle transport with the theoretical steepness of the wave group at the focus point $mathcal {S}$ (Deike et al. Reference Deike, Pizzo and Melville 2017), in contrast to the quadratic scaling of Stokes drift with steepness for non-breaking waves.
Spontaneous symmetry breaking is a very common occurrence in many-body systems. Ordi-nary crystals break translation symmetry down to a discrete subgroup. …
In dry batch ball milling, grinding kinetics follow a linear model. Linear breakage kinetics are said to prevail in a mill when neither the probability of breakage of a particle (as measured by the breakage rate function) nor the distribution of fragments resulting from the primary breakage of that particle (as measured by the breakage distribution function) is …

A linear particle accelerator is a type of particle accelerator that accelerates charged subatomic particles or ions to a high speed by subjecting them to a series of oscillating electric potentials along a linear beamline. The principles for such machines were proposed by Gustav Ising in 1924, while the first machine that worked was constructed by Rolf Widerøe in 1928 at the RWTH …
