“…In a previous paper [3], we investigated the possibility of reviving the superconnection formalism first discussed in 1979 by Ne'eman [4], Fairlie [5,6], and others [7][8][9]. The original observation of Ne'eman was that the SU{2)L x U(\)Y gauge fields and the Higgs doublet in the SM could be embedded into a single su(2/1) superconnection [10,11] with the SU(2)L x t/(l)y gauge fields constituting the even part of the superconnection and the Higgs doublet 4 > constituting the odd part, to wit: where W = IV,-t,-.…”

“…The same scale should also characterize the separation of the two branes in the discrete direction. Given the current experimental knowledge of the SM, this scale turns out to be ~4 TeV [3], suggesting a phenomenology that could potentially be explored at the LHC, as well as the existence of a new fundamental scale of nature at those energies. We will have more to say about this later.…”

“…4The unitary condition renders the resulting gauge theory anomaly free [51]. 045020-2 for instance, the prediction for the t/( l) x SU (2) x SU (3) gauge couplings are of the 50(10) grand unified theory (GUT) type, pushing up the scale of emergence to the GUT scale. The spectral SM is not particularly predictive either: the fermionic masses and mixings must all be put in by hand into the operator D. Thus, the NCG-superconnection approach still has much to be desired and further develop ment is called for.…”

“…As discussed in Ref. [3], lowering this pre diction down to ~126 GeV requires the introduction of extra scalar degrees of freedom which modify the renorm alization group equations (RGE) of the Higgs couplings. Those degrees of freedom would be available, for instance, if the su(2/l) superconnection were extended to su (2/2).…”

We discuss the physical implications of formulating the Standard Model (SM) in terms of the superconnection formalism involving the superalgebra su(2/1). In particular, we discuss the prediction of the Higgs mass according to the formalism and point out that it is -170 GeV, in clear disagreement with experiment. To remedy this problem, we extend the formalism to the superalgebra su(2/2), which extends the SM to the left-right symmetric model (LRSM) and accommodates a -1 2 6 GeV Higgs boson. Both the SM in the su(2/1) case and the LRSM in the su(2/2) case are argued to emerge at -4 TeV from an underlying theory in which the spacetime geometry is modified by the addition of a discrete extra dimension. The formulation of the exterior derivative in this model space suggests a deep connection between the modified geometry, which can be described in the language of noncommutative geometry, and the spontaneous breaking of the gauge symmetries. The implication is that spontaneous symmetry breaking could actually be geometric/quantum gravitational in nature. The nondecoupling phenomenon seen in the Higgs sector can then be reinterpreted in a new light as due to the mixing of low energy (SM) physics and high energy physics associated with quantum gravity, such as string theory. The phenomenology of a TeV scale LRSM is also discussed, and we argue that some exciting discoveries may await us at the LHC, and other near-future experiments.

Motivated by possible scalar-leptoquark explanations of the recently reported B-decay anomalies, we investigate whether the required leptoquarks can be accommodated within models based on noncommutative geometry (NCG). The models considered have the gauge structure of Pati-Salam models, SU (4) × SU (2) L × SU (2) R , with gauge coupling unification at a single scale. In one of the models, we find a unique scalar leptoquark with quantum numbers (3, 1, − 1 3 ) 321 , originating from a complex multiplet (6, 1, 1) 422 , which can potentially explain the B-decay anomalies if its mass is on the order of a few TeV. The unification of couplings can be realized with the inclusion of a single step of intermediate symmetry breaking. The scalar leptoquark under consideration does not contribute to proton decay due to the absence of diquark couplings, as dictated by the underlying noncommutative geometry. 11 See, for instance, Ref. [75]. 12 The authors of Refs. [3,4] use I = 1, 2, 3, 4 to label the SU (4) index, and then use I = (1, i), with i = 1, 2, 3 to distinguish between the leptons and quarks. We instead use I = 0, 1, 2, 3, which seems more self-evident to us.
