“…Among these approaches, numerous mainstream unification candidates (and variations of them) exist, including, superstring theory [6], QG, loop quantum gravity (LQG) [7][8][9][10][11], Chern-Simons theory [12], Yukawa (10) theory [13], E8 theory [14], and others. Frequently, components and ideas from different theories are combined, adjusted, and "hacked" together (i.e., copy-andpaste methods) to establish new hybrid theoretical frameworks with customized capabilities, such as semiclassical physics, which intertwines aspects of quantum mechanics and classical mechanics.…”

“…Currently, none of these candidates are accepted to be complete by mainstream science. For example, some frameworks like superstring theory [6], 2 Advances in High Energy Physics Yukawa (10) theory [13], and E8 theory [14] are incomplete because they require more spatial degrees of freedom to operate than 4D space-time can offer so they cannot be tested in the laboratory, while other theories are incomplete because they fail to fully describe paradoxical phenomena like BHs, which remain imposing and elusive and continue to violate the modern laws of physics. Hence, the theories must be subjected to additional stringent scientific research, scrutiny, debate, and experimentation so they can continue to evolve and achieve improved representational capabilities.…”

“…Thus, from among the mentioned candidates, we have selected a semiclassical platform to launch a probe of BHs that exemplifies the underlying QG theory. For this work, we prefer this semiclassical, QG-based approach over existing unification candidates such as superstring theory [6], Yukawa (10) theory [13], and E8 theory [14] because their gravitational treatment adds too many spatial degrees of freedom. Moreover, a popular alternative to QG is LQG [7][8][9][10][11], which does have 4D space-time gravity built-in by default because it fundamentally operates on the principles of general relativity.…”

Black hole (BH) area quantization may be the key to unlocking a unifying theory of quantum gravity (QG). Surmounting evidence in the field of BH research continues to support a horizon (surface) area with a discrete and uniformly spaced spectrum, but there is still no general agreement on the level spacing. In the specialized and important BH case study, our objective is to report and examine the pertinent groundbreaking work of the strictly thermal and nonstrictly thermal spectrum level spacing of the BH horizon area quantization with included entropy calculations, which aims to tackle this gigantic problem. In particular, such work exemplifies a series of imperative corrections that eventually permits a BH's horizon area spectrum to be generalized from strictly thermal to nonstrictly thermal with entropy results, thereby capturing multiple preceding developments by launching an effective unification between them. Moreover, the results are significant because quasi-normal modes (QNM) and "effective states" characterize the transitions between the established levels of the nonstrictly thermal spectrum.

“…In this scenario the desired supersymmetric threshold corrections to t-b-τ Yukawa couplings can be realized with Mg mb [12][13][14][15][16][17]. For a particular choice of SSB gaugino masses (M 1 : M 2 : M 3 = 1 : 3 : −2) at M GUT , which can be derived in the framework of SO(10) GUT, it was shown [18,19] that the CP-even SM-like Higgs boson mass m h ≈ 125 GeV can be predicted from t-b-τ YU. This result does not change much in terms of the Higgs mass prediction if we relax t-b-τ YU up to 10% [18,19].…”

“…On the other hand, imposing t-b-τ Yukawa coupling unification condition at M GUT [6][7][8] can place significant constraints on the supersymmetric spectrum in order to fit the top, bottom and tau masses. These constraints are quite severe [9][10][11][12][13][14][15][16][17][18][19], especially after the discovery of a SM like Higgs boson with mass, m h 125 − 126 GeV [20,21].…”

We consider two distinct classes of Yukawa unified supersymmetric SO(10) models with non-universal and universal soft supersymmetry breaking (SSB) gaugino masses at M GUT . In both cases, we assume that the third family SSB sfermion masses at M GUT are different from the corresponding sfermion masses of the first two families (which are equal). For the SO(10) model with essentially arbitrary (non-universal) gaugino masses at M GUT , it is shown that t-b-τ Yukawa coupling unification is compatible, among other things, with the 125 GeV Higgs boson mass, the WMAP relic dark matter density, and with the resolution of the apparent muon g − 2 anomaly. The colored sparticles in this case all turn out to be quite heavy, of order 5 TeV or more, but the sleptons (smuon and stau) can be very light, of order 200 GeV or so. For the SO(10) model with universal gaugino masses and NUHM2 boundary conditions, the muon g − 2 anomaly cannot be resolved. However, the gluino in this class of models is not too heavy, 3 TeV, and therefore may be found at the LHC.

A brief review is given of the implications of a 126 GeV Higgs boson for the discovery of supersymmetry. Thus a 126 GeV Higgs boson is problematic within the Standard Model because of vacuum instability pointing to new physics beyond the Standard Model. The problem of vacuum stability is overcome in the SUGRA GUT model but the 126 GeV Higgs mass implies that the average SUSY scale lies in the several TeV region. The largeness of the SUSY scale relieves the tension on SUGRA models since it helps suppress flavor changing neutral currents and CP violating effects and also helps in extending the proton life time arising from baryon and lepton number violating dimension five operators. The geometry of radiative breaking of the electroweak symmetry and fine tuning in view of the large SUSY scale are analyzed.Consistency with the Brookhaven g μ − 2 result is discussed. It is also shown that a large SUSY scale implied by the 126 GeV Higgs boson mass allows for light gauginos (gluino, charginos, neutralinos) and sleptons. These along with the lighter third generation squarks are the prime candidates for discovery at RUN II of the LHC. Implication of the 126 GeV Higgs boson for the direct search for dark matter is discussed. Also discussed are the sparticles mass hierarchies and their relationship with the simplified models under the Higgs boson mass constraint.In 2012 the Large Hadron Collider (LHC) made a landmark discovery of a new boson. Thus the CMS and AT-LAS collaborations discovered a boson with a mass of ∼126 GeV [1][2][3][4]. It is now confirmed that this newly discovered particle is the long sought after Higgs boson [5][6][7][8] which plays a central role in the breaking of the electroweak symmetry. While the observed particle is the last missing piece of the Standard Model there are strong indications that at the same time its discovery portends discovery of a new realm of physics specifically supersymmetry. Below we elaborate on this theme in further detail.The outline of the rest of the paper is as follows: In Section 1 we discuss the status of the Higgs boson in the Standard Model, the issue of vacuum instability and the need for new physics beyond the Standard Model. In Section 2 we consider the implications of a 126 GeV Higgs boson within the framework of supersymmetry and specifically in the framework of supergravity unified models. As is well known a 126 GeV Higgs boson within supersymmetry leads to a high SUSY scale M s with M s lying in the TeV region. On the other hand the Brookhaven g μ − 2 experiment [9] shows a 3σ deviation from the Standard Model prediction [10,11]. An effect of this size requires that the average scale of sparticle masses entering the loops in the supersymmetric electroweak correction to g μ − 2 be low, i..e, O(100) GeV. Assuming the 3σ effect is robust we discuss in Section 3 how to reconcile the high SUSY scale that is indicated by the 126 GeV Higgs boson mass with the low SUSY scale indicated by the Brookhaven experiment. In Section 4 we discuss the implications of the Higgs ...
