“…Thereafter, within the above section we will show the results of scanning over a wide region of µ − A t plane for a moderate as well as for a large value of tan β. We also discuss the compatibility of our analysis with relevant low energy constraints like those from B-physics and cosmological constraints from neutralino dark matter [48][49][50][51]. We will further discuss the issue of muon g − 2 in the context of long-lived vacuum scenario, presenting also a few benchmark points.…”

Exploring MSSM parameter space after the discovery of Higgs Boson at 125 GeV naturally demands large top-squark mixing or large trilinear coupling parameter A t in particular, so as to avoid excessively heavy squark, specially for the universal models like CMSSM. We study stability of electroweak symmetry breaking vacua in possible presence of deeper charge-color symmetry breaking minima within MSSM. Besides stable vacua, we consider scenarios characterized by the presence of global CCB minima, with SM like charge and color conserving vacuum, having stability over cosmologically large lifetime (long-lived states). We allow vacuum expectation values for both stop as well as sbottom fields, since these belong to the third generation of sfermions with larger Yukawa couplings that have immediate effect on the tunneling time. Moreover, for large µ regions, radiative corrections to Higgs boson mass from bottom-squark loop is quite significant. Regions of MSSM parameters space become viable for large A t and large µ zones which are generically excluded via the traditional analytical CCB constraints. For a large value of tan β, safe vacua associated with large values of |µ| and |A t | are predominantly long-lived and may be associated with relatively light stop masses. We also identify low µ regions associated with long-lived states. Both the above zones can be friendly to muon g − 2 constraint. We also impose constraints from Br(B → X s γ) and Br(B s → µ + µ − ). We do the analysis for a moderate and a large tan β. We choose an example parameter point in the gaugino mass plane of M 1 , M 2 that satisfies the dark matter constraints, basically a decoupled sector with respect to CCB.

“…[31][32][33][34][35] The fabric of space, consisting of Dark Matter Molecules, in gaseous, liquid, sold and perhaps even dark plasma states, [2] is sufficient to explain both Dark Energy and Dark Matter related astronomy, astrophysics and cosmology related observations, but is not mutually exclusive either. [36][37][38][39][40][41][42] Although the following section only describes the two most common forms of Dark Matter atoms, it doesn't preclude others, including the pion, SIMP, WIMP, axion, MACHO, Kaluza-Klein, gravitino, and any other supersymmetric particles. [43] Some estimates go as high as 73% of the universe consists of Dark Energy.…”

Abstract:A unifying model and theory that covers dark matter, dark energy, gravity, space and negative energy by means of observation, citation, and deduction, revealing a fundamental definition for both space and gravity, support of dark energy theory, explanation of dark matter, revealing additional structure and properties of baryonic atoms, sheds new light on baryogenesis, and revises estimates of the longevity of the universe. Other matters discussed are aerospace, anti-gravity, artificial gravity, gravitational waves, wormholes, interstellar space travel, cold fusion, cold fission, health and wellbeing, the earth's atmosphere and global warming.

“…However, a number of different categories of astronomical observations are explained in the usual Euclidean 3-space only in terms of so far undetermined dark matter and dark energy: rotational curves of galaxies [14][15][16][17], gravitational lensing [18][19][20], application of the virial theorem to galaxy clusters [21][22][23] and the acceleration of the expansion of the universe [24][25][26][27][28][29]. This already happens before the transition from the ordinary space-time to the cosmological one, the FLWR space-time which is not a Galilean space-time but has nearly internally flat 3-spaces and uses a theoretical cosmic time.…”

“…The fixation of the York time determines the sequence of instantaneous non-Euclidean 3-spaces Σ τ of the 3þ1 splitting of space-time centered on an observer either on the Earth or on the Space Station 19 : all the clocks on each 3-space are synchronized with the atomic clock (τ is its proper time) of the observer at the intersection of the 3-space with the observer world line. This time metrology convention implies also the determination of the lapse function, which describes how the unit of time of the atomic clock changes when one goes from a 3-space to an infinitesimally near successive one.…”

Relativistic Celestial Metrology: Dark Matter as an Inertial Gauge Effect

In canonical tetrad gravity, it is possible to identify the gauge variables, describing relativistic inertial effects, in Einstein general relativity. One of these is the York time, the trace of the extrinsic curvature of the instantaneous non-Euclidean 3-spaces (global Euclidean 3-spaces are forbidden by the equivalence principle). The extrinsic curvature depends both on gauge variables and on dynamical ones like the gravitational waves after linearization. The fixation of these gauge variables is done by relativistic metrology with its identification of time and space. Till now, the International Celestial Reference Frame ICRF uses Euclidean 3-spaces outside the Solar System. It is shown that York time and non-Euclidean 3-spaces may explain the main signatures of dark matter in ordinary space-time before using cosmology. Also dark energy may be connected to these inertial gauge effects, because both red-shift and luminosity distance depend on them.
