Nuclear and Particle Physics is an accessible, balanced introduction to the subject and provides a readable and up-to-date overview of both. Laboratory for High Energy Physics, University of Bern, Switzerland .. an introduction to nuclear and particle physics for undergraduate students at the bachelor. It is common practice to teach nuclear physics and particle physics together in an the majority – will be the only time they study nuclear and particle physics.

Pages to Extent pp. Also, bosons can be either elementary, like photons, or a combination, like mesons. The spin of bosons are integers instead of half integers. Main article: Gluon Gluons mediate the strong interaction , which join quarks and thereby form hadrons , which are either baryons three quarks or mesons one quark and one antiquark.
Protons and neutrons are baryons, joined by gluons to form the atomic nucleus. Like quarks, gluons exhibit color and anticolor—unrelated to the concept of visual color—sometimes in combinations, altogether eight variations of gluons.
The W bosons are known for their mediation in nuclear decay. The Z0 does not convert charge but rather changes momentum and is the only mechanism for elastically scattering neutrinos. The weak gauge bosons were discovered due to momentum change in electrons from neutrino-Z exchange. The massless photon mediates the electromagnetic interaction.
These four gauge bosons form the electroweak interaction among elementary particles. Main article: Higgs boson Although the weak and electromagnetic forces appear quite different to us at everyday energies, the two forces are theorized to unify as a single electroweak force at high energies.
The differences at low energies is a consequence of the high masses of the W and Z bosons, which in turn are a consequence of the Higgs mechanism. Through the process of spontaneous symmetry breaking , the Higgs selects a special direction in electroweak space that causes three electroweak particles to become very heavy the weak bosons and one to remain with an undefined rest mass as it is always in motion  the photon.
On 4 July , after many years of experimentally searching for evidence of its existence, the Higgs boson was announced to have been observed at CERN's Large Hadron Collider. Peter Higgs who first posited the existence of the Higgs boson was present at the announcement.
In particle physics, this is the level of significance required to officially label experimental observations as a discovery. Research into the properties of the newly discovered particle continues.
Main article: Graviton The graviton is a hypothetical elementary spin-2 particle proposed to mediate gravitation.
While it remains undiscovered due to the difficulty inherent in its detection , it is sometimes included in tables of elementary particles. Theories beyond the Standard Model attempt to resolve these shortcomings. Main article: Grand Unified Theory One extension of the Standard Model attempts to combine the electroweak interaction with the strong interaction into a single 'grand unified theory' GUT.
Such a force would be spontaneously broken into the three forces by a Higgs-like mechanism. The most dramatic prediction of grand unification is the existence of X and Y bosons , which cause proton decay. Main article: Supersymmetry Supersymmetry extends the Standard Model by adding another class of symmetries to the Lagrangian. These symmetries exchange fermionic particles with bosonic ones.
Such a symmetry predicts the existence of supersymmetric particles , abbreviated as sparticles , which include the sleptons , squarks , neutralinos , and charginos. Due to the breaking of supersymmetry , the sparticles are much heavier than their ordinary counterparts; they are so heavy that existing particle colliders would not be powerful enough to produce them.
Main article: String theory String theory is a model of physics where all "particles" that make up matter are composed of strings measuring at the Planck length that exist in an dimensional according to M-theory , the leading version or dimensional according to F-theory  universe. These strings vibrate at different frequencies that determine mass, electric charge, color charge, and spin.

A string can be open a line or closed in a loop a one-dimensional sphere, like a circle. As a string moves through space it sweeps out something called a world sheet.Enter your email address below and we will send you your username.
