Abstract

We investigate the physical implications of formulating the electroweak (EW) part of the Standard Model (SM) in terms of a superconnection involving the supergroup SU(2/1). In particular, we relate the observed Higgs mass to new physics at around 4 TeV. The ultraviolet incompleteness of the superconnection approach points to its emergent nature. The new physics beyond the SM is associated with the emergent supergroup SU(2/2), which is natural from the point of view of the Pati-Salam model. Given that the Pati-Salam group is robust in certain constructions of string vacua, these results suggest a deeper connection between low energy (4 TeV) and high energy (Planck scale) physics via the violation of decoupling in the Higgs sector.

Higgs mass, superconnections, and the TeV-scale left-right symmetric model

Journal Article Aydemir, Ufuk ; Minic, Djordje ; Sun, Chen ; ... - Physical Review. D, Particles, Fields, Gravitation and Cosmology

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 ~126 GeV Higgs. 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 underlyingmore »« less

LHC signals for coset electroweak gauge bosons in warped/composite pseudo-Goldstone boson Higgs models

Journal Article Agashe, Kaustubh ; Azatov, Aleksandr ; Lijun, Zhu ; ... - Physical Review. D, Particles Fields

The framework of a warped extra dimension with the standard model (SM) fields propagating in it is a very well-motivated extension of the SM since it can address both the Planck-weak and flavor hierarchy problems of the SM. Within this framework, solution to the little hierarchy problem motivates extending the SM electroweak (EW) 5D gauge symmetry in such a way that its breakdown to the SM delivers the SM Higgs boson. We study signals at the large hadron collider (LHC) for the extra EW (called coset) gauge bosons, a fundamental ingredient of this framework. The coset gauge bosons, due tomore »« less

Gedanken worlds without Higgs fields: QCD-induced electroweak symmetry breaking

Journal Article Quigg, Chris ; Institut fuer Theoretische Teilchenphysik, Universitaet Karlsruhe, D-76128 Karlsruhe ; Shrock, Robert - Physical Review. D, Particles Fields

To illuminate how electroweak symmetry breaking shapes the physical world, we investigate toy models in which no Higgs fields or other constructs are introduced to induce spontaneous symmetry breaking. Two models incorporate the standard SU(3){sub c} x SU(2){sub L} x U(1){sub Y} gauge symmetry and fermion content similar to that of the standard model. The first class--like the standard electroweak theory--contains no bare mass terms, so the spontaneous breaking of chiral symmetry within quantum chromodynamics is the only source of electroweak symmetry breaking. The second class adds bare fermion masses sufficiently small that QCD remains the dominant source of electroweakmore »« less

Inflation, proton decay, and Higgs-portal dark matter in $$$$SO(10) \times U(1)_\psi $$$$

Journal Article Okada, Nobuchika ; Raut, Digesh ; Shafi, Qaisar - European Physical Journal. C, Particles and Fields

We propose a simple non-supersymmetric grand unified theory (GUT) based on the gauge group SO(10)×U(1)_ψ. The model includes 3 generations of fermions in 16 (+1), 10 (–2) and 1 (+4) representations. The 16-plets contain Standard Model (SM) fermions plus right-handed neutrinos, and the 10-plet and the singlet fermions are introduced to make the model anomaly-free. Gauge coupling unification at M_GUT≃5×10¹⁵ - 10¹⁶ GeV is achieved by including an intermediate Pati–Salam breaking at M_I ≃ 10¹² – 10¹¹ GeV, which is a natural scale for the seesaw mechanism. For M_I ≃ 10¹² – 10¹¹, proton decay will be tested by themore »« less

Astrophysical implications of a visible dark matter sector from a custodially warped GUT

Journal Article Agashe, Kaustubh ; Blum, Kfir ; Lee, Seung J ; ... - Physical Review. D, Particles Fields

We explore, within the warped extra dimensional framework, the possibility of finding antimatter signals in cosmic rays (CRs) from dark matter (DM) annihilation. We find that exchange of order 100 GeV radion, an integral part of this class of models, generically results in a sizable Sommerfeld enhancement of the annihilation rate for DM mass at the TeV scale. No ad hoc dark sector is required to obtain boosted annihilation cross sections and hence signals. Such a mild hierarchy between the radion and DM masses can be natural due to the pseudo-Goldstone boson nature of the radion. We study the implicationsmore »« less
