It is pointed out that in supersymmetric models with a new gauge symmetry under which the Higgs is charged, the fine-tuning of the electroweak symmetry breaking is relaxed due to suppression of the top Yukawa coupling at higher scales by a new large gauge coupling. We calculate the fine-tuning in an explicit model and find that the lower bounds on stops and gluino masses from the naturalness criterion are increased by several hundred GeV in comparison to the Minimal Supersymmetric Standard Model (MSSM). The fine-tuning is improved by one to two orders of magnitude as compared to the MSSM, as a consequence of both the suppression of the top Yukawa coupling and the additional tree-level contribution to the Higgs mass allowing for much lighter stops.

“…This is because the quality of the SUð4Þ symmetry requires a large SUð4Þ invariant quartic term which points to UV completions based on composite Higgs models [8][9][10][11]. SUSY UV completions of the TH model also exist [12][13][14][15][16][17]. Acceptable tuning of the electroweak (EW) scale at the level of 5%-10% can be, however, obtained only with a low Landau pole scale, which requires UV completion by some strong dynamics.…”

Twin Higgs (TH) models explain the absence of new colored particles responsible for natural electroweak symmetry breaking (EWSB). All known ultraviolet completions of TH models require some nonperturbative dynamics below the Planck scale. We propose a supersymmetric model in which the TH mechanism is introduced by a new asymptotically free gauge interaction. The model features natural EWSB for squarks and gluino heavier than 2 TeV even if supersymmetry breaking is mediated around the Planck scale, and has interesting flavor phenomenology including the top quark decay into the Higgs boson and the up quark which may be discovered at the LHC. DOI: 10.1103/PhysRevLett.120.211803 Introduction.-Models of natural electroweak symmetry breaking (EWSB), e.g., supersymmetric (SUSY) models [1][2][3][4] and composite Higgs models [5,6], generically predict new light colored particles, called top partners, so that the quantum correction to the Higgs mass is suppressed. Null results of the LHC searches, however, show that new colored particles are heavy, which calls for fine-tuning of the parameters of the theories; this is known as the little hierarchy problem. In light of this fact the idea that the light top partners are not charged under the standard model (SM) SUð3Þ c gauge group has become increasingly attractive. Twin Higgs (TH) models [7] are one of the most studied realizations of the idea.A crucial ingredient of TH models is an approximate global SUð4Þ symmetry under which the SM Higgs boson and its mirror (or twin) partner transform as a fundamental representation. The Higgs boson is a pseudo-NambuGoldstone boson associated with the spontaneous breakdown of the SUð4Þ symmetry. The SUð4Þ symmetry of the Higgs mass term emerges from a Z 2 symmetry exchanging the SM fields with their mirror counterparts. The light top partners are then charged under the mirror gauge group rather than the SM one. Standard lore says that ultraviolet (UV) completion of TH models involves some nonperturbative dynamics. This is because the quality of the SUð4Þ

Twin Higgs models are the prime illustration of neutral naturalness, where the new particles of the twin sector, gauge singlets of the Standard Model (SM), ameliorate the little hierarchy problem. In this work, we analyse phenomenological implications of the heavy Higgs of the Mirror Twin Higgs and Fraternal Twin Higgs models, when electroweak symmetry breaking is linearly realized. The most general structure of twin Higgs symmetry breaking, including explicit soft and hard breaking terms in the scalar potential, is employed. The direct and indirect searches at the LHC are used to probe the parameter space of Twin Higgs models through mixing of the heavy Higgs with the SM Higgs and decays of the heavy Higgs to the SM states. Moreover, for the Fraternal Twin Higgs, we study the production and decays of twin glueball and bottomonium states to the SM light fermions, which have interesting signatures involving displaced vertices and are potentially observable at the colliders.
