The standard model is about the group symmetry of the quaternion multiplication identity in spacetime. OK, but what does that mean? Here is my take. Observers sit at here-now in spacetime, or numerically at (0, 0, 0, 0). An observer sees something out there, and tries to characterize the thingie The standard model from the theoreticians point of view is a set of local and global symmetries, which constraint the overall form of the theory. This skeleton is then fleshed out by adding to the symmetries particles such that they respect the symmetries. Furthermore, interactions between the particles are added, which superficially respect the at least the local symmetries, i.e. they do not break them explicitly Standard Model of Particle Physics. The diagram shows the elementary particles of the Standard Model (the Higgs boson, the three generations of quarks and leptons, and the gauge bosons), including their names, masses, spins, charges, chiralities, and interactions with the strong, weak and electromagnetic forces. It also depicts the crucial role of the Higgs boson in electroweak symmetry.

** The Standard Model of particle physics is the theory describing three of the four known fundamental forces (the electromagnetic, weak, and strong interactions, and not including the gravitational force) in the universe, as well as classifying all known elementary particles**.It was developed in stages throughout the latter half of the 20th century, through the work of many scientists around the. The complete theory which is the Standard Model will be developed and all its symmetries will be investigated. Sym- metries, corresponding to conserved currents in nature, can occur both on a local and global scale. The local symmetries, mathematically denoted as SU(3

- The Standard Model of particle physics is often visualized as a table, similar to the periodic table of elements, and used to describe particle properties, such as mass, charge and spin. The table is also organized to represent how these teeny, tiny bits of matter interact with the fundamental forces of nature. But it didn't begin as a table

- An extraordinary cancellation between two apparently unrelated parameters in the Standard Model endows the neutron with an essentially symmetric distribution of electric charge, implying that quantum chromodynamics (QCD) conserves parity and time reversal symmetries P and CP, despite the fact that both are broken by electroweak interactions.Axion models provide a popular explanation to this.

Symmetries in the quantum world. In part 1 of the Particle Physics series, we discussed the different particles that make up the universe. These were mainly the quarks, the leptons and the bosons. There are shown here in the Standard Model: The Standard Model of Particle Physics. Image from Wikipedi The symmetries of the Standard Model associated with the Electroweak and Strong (QCD) forces are described by the groups U(1), SU(2) and SU(3). The properties of these groups are examined and the relevance to particle physics is discussed.Stephen Haywood,. The Standard Model incorporates all the fundamental particles including the recently discovered Higgs particle. However, the Standard Model is elaborate and involves many parameters. Possible next steps to make sense of these include: (a)Beyond-the-Standard-Model physics (including more particles, SUSY, or dark matter), an N-Higgs-doublet models (NHDM) are among the most popular examples of electroweak symmetry breaking mechanisms beyond the Standard Model. Discrete symmetries im

- The Standard Model (SM) of particle physics has been one of the most precisely tested theories in physics. However, the SM has various non-generic features, which are tightly related to the fact that it has a number of accidental symmetries, approximately symmetries and large hierarchy among the dimensionless parameters
- The Standard Model includes the electromagnetic, strong and weak forces and all their carrier particles, and explains well how these forces act on all of the matter particles. However, the most familiar force in our everyday lives, gravity, is not part of the Standard Model, as fitting gravity comfortably into this framework has proved to be a difficult challenge
- The Standard Model of Particle Physics has many (19) free parameters, most of which (13) are related to the masses and mixing angles of the elementary fermions (quarks and leptons). If we include neutrino masses, even 22 of the 28 parameters are related to the fermion mass sector
- Both Grand Unified symmetries and discrete flavour symmetries are appealing ways to describe apparent structures in the gauge and flavour sectors of the Standard Model. Both symmetries put constraints on the high energy behaviour of the theory. This can give rise to unexpected interplay when building models that possess both symmetries

- Searches for new physics beyond the Standard Model (SM) at the LHC are mainly driven by two approaches: a signature-based search where one looks for a deviation from the SM prediction in event yield or kinematic properties, and a more theory-oriented approach where the search is designed to look for specific signatures/topologies predicted by certain beyond standard model (BSM ) scenarios
- The rare decay B -> K* (-> K pi) mu+ mu- is regarded as one of the crucial channels for B physics as the polarization of the K* allows a precise angular reconstruction resulting in many observables that offer new important tests of the Standard Model and its extensions

I will describe Connes approach to the standard model based on spectral noncommutative geometry with particular emphasis on the symmetries. The model poses constraints which are satisfied by the standard model group, and does not leave much room for other possibilities. There is however a possibility for a larger symmetry (the ``grand algebra'') which may also be instrumenta Physics below 300 GeV is termed infrared, and physics above 1 TeV is called ultraviolet. Some aspects of the relation between these two regions are discussed. It is argued that the symmetries of the infrared must be symmetries in the ultraviolet. Furthermore, naturalness within the context of the standard model is considered Abstract (APS) We derive the complete set of continuous maximal symmetries for standard model (SM) alignment that may occur in the tree-level scalar potential of multi-Higgs doublet models, with n>2 Higgs doublets. Our results generalize the symmetries of SM alignment, without decoupling of large mass scales or fine-tuning, previously obtained in the context of two-Higgs doublet models

All the physics we know with certainty today at microscopic or macroscopic distance scales is embodied in principle in the fundamental laws described by the Standard Model of Particles and Forces, and in General Relativity. In 2006 I discovered the 2T Standard Model and in 2008 2T-Gravity, both in 4-space and 2-time dimensions In this paper, I propose a new model compatible with the internal symmetries of elementary particles to identify the invariant charges of standard model unitary symmetries by physical parameters in an extra spatial dimension. Applying the concepts of zero point energy and center of mass for elementary particles and introducing >helixons</i> as time-like geodesics in 4+1 dimensional toral. Gauge symmetries are more complicated, but they, too, lead to conservation laws. In this case the conserved quantities are charges like the electric charge. The standard model possesses three distinct gauge symmetries, which define the charges for the electromagnetic, weak, and strong forces N-Higgs-doublet models (NHDM) are among the most popular examples of electroweak symmetry breaking mechanisms beyond the Standard Model. Discrete symmetries imposed on the NHDM scalar potential play a pivotal role in shaping the phenomenology of the model, and various symmetry groups have been studied so far. However, in spite of all efforts, the classification of finite Higgs-family symmetry.
