*the standard model of ‘particle physics’ is a ‘theory’ concerning the [(‘electro-magnetic’ / ‘weak’ / ‘strong’) ‘nuclear interactions’], as well as ‘classifying’ all the ‘sub-atomic particles’ known*
.
(it was developed throughout the latter half of the ‘1900s’ as a collaborative effort of ‘scientists’ around the ‘world’)
(the ‘current formulation’ was finalized in the ‘mid-1970s’ upon ‘experimental confirmation’ of the ‘existence’ of ‘quarks’)
(since then, discoveries of the ‘top quark’ (‘1995’), the ‘tau neutrino’ (‘2000’), and the ‘higgs-boson’ (‘2012’) have given further credence to the ‘standard model’)
(because of its ‘success’ in explaining a wide variety of ‘experimental results’, the ‘standard model’ is sometimes regarded as the “theory of ‘(almost’) everything'”)
(although the ‘standard model’ is believed to be theoretically ‘self-consistent’ and has demonstrated ‘huge’ + ‘continued’ successes in ‘providing experimental predictions’, it does leave some ‘phenomena’ unexplained and it falls short of being a “‘complete theory’ of ‘fundamental interactions'”)
(it does not incorporate the ‘full theory of gravitation” as described by ‘general relativity’, or account for the ‘accelerating expansion of the ‘universe” (as possibly described by ‘dark energy’))
(the ‘model’ does not contain any viable ‘dark matter particle’ that possesses all of the ‘required properties’ deduced from ‘observational cosmology’)
(it also does not incorporate ‘neutrino oscillations’ (and their ‘non-zero masses’))
(the development of the ‘standard model’ was driven by ‘theoretical’ and ‘experimental’ *particle physicists* alike)
(for ‘theorists’, the ‘standard model’ is a ‘paradigm’ of a ‘quantum field theory’, which exhibits a wide range of ‘physics’ including ‘spontaneous symmetry breaking’, ‘anomalies’, and ‘non-perturbative behavior’)
.
(it is used as a basis for building more ‘exotic models’ that incorporate ‘hypothetical particles’, ‘extra dimensions’, and ‘elaborate symmetries’ (such as ‘super-symmetry’) in an attempt to explain ‘experimental results’ at variance with the ‘standard model”, such as the existence of ‘dark matter’ + ‘neutrino oscillations’)
