What is the physical nature of gravitinos? As asked before, this question was the template of how to introduce Machian Physics as a way to link gravitinos in the electro weak era and gravitons as of the present. What we wish to do now is to ask how a flaw in the Higgs equation as brought up by Comay shows a branch off from orthodox quantum physics, leading to, with the Machs principle application done earlier a way to embed the beginning of the universe as a semi classical superstructure of which Quantum Mechanics is a subset of. We argue that this will necessitate a review of the Higgs equation of state for reasons stated in the manuscript. We also finally review a proprosal for another form of mass formation mechanism as a replacement for the Higgs mass as introduced by Glinka and Beckwith, 2012, with commentary as to how suitable it may be to get a gravitino mass in fidelity to the Machian proposal introduced by Beckwith previously, to get linkage between electroweak era gravitinos and present day gravitons. 展开更多

In this paper, we consider the localization of a five-dimensional gravitino field on f(R)-thick branes. We obtain the coupled chiral equations of the Kaluza-Klein(KK) modes of gravitinos with the gauge condition Ψ_z= 0. The chiral equations of a gravitino's KK modes are found to be almost identical to those of the Dirac fermion. However, their chiralities are exactly opposite. The chiral KK modes of gravitinos could be localized in some types of f(R)-thick branes on introducing a coupling term. We investigate the localization of a gravitino on three types of f(R)-thick branes through a Yukawa-like coupling term with background scalar fields. It has been shown that all the KK modes of gravitinos cannot be localized in the pure geometric f(R)-thick branes by adding a five-dimensional gravitino mass term. However, for the f(R)-thick branes generated by one or two background scalar fields, only the left-or right-handed zero mode could be localized in the branes, and the massive KK resonant modes are the same for both left-and right-handed gravitinos despite their opposing chiralities. All these results are consistent with those of the five-dimensional Dirac fermion except their chiralities, which may be an important sign to distinguish the gravitino field and the Dirac fermion field. 展开更多

Our interest is in dynamical aspects of these fields. An explicit novel expression for the propagator of the massless Rarita-Schwinger field (the gravitino), in the mass spectrum involving massless fermions in superstring theory in 10 dimensions, is derived. The analysis is carried in the presence of a non-constrained external source so that the full expression of the propagator emerges. The number of associated degrees of freedom is also obtained. We work in a Coulomb-like gauge. The massless Dirac field (the dilatino), the other massless fermion field in the mass spectra of superstring theory in 10 dimensions, is first investigated to this end. 展开更多

This paper is about the theory of “basic gravitinoes” (in early papers, it was referred to WG) in the material world, which make up the “dark matter” and the elementary particles as well. The strong interaction is generated by the Pressure Effect, which is resulted in the accumulation of the overall gravitation from all the galaxy gravitinoes. The Model for Stable-state Particle Basic Body indicates three stable states which correspond to protons, electrons and neutrons respectively and have been proven by all the particle collision experiments. It’s the root cause that only the short-lived particles resulted in the collisions. The study is supported by all experiments of light propagation, especially the wave-particle duality, and tries to make the theoretical interpretation for three laws of electromagnetic experiment so that the Maxwell’s field equations are derived ultimately and theoretically. 展开更多

The early electro weak regime as of 10-32 seconds after the big bang is where we could see the initial formation of gravitons, gravitinos and GW. What we intend to do is to look at if Mach’s principle, and a statement of overall quantized energy state behavior of the universe can help us get hij , using initial conditions as initially presented by Mishra in 2012 we restate as . Mach’s principle was used by Mishra, and we use it to come up with conditions for a stable overall mass M contributing to GW generation/ entropy of the universe. The composition of M for gravitons would change over time from initial beginnings to the present day, but the final invariant graviton mass M we work with is a way to state initial and final numbers, N, of the constituent particles contributing to entropy of our universe. By the way of comparison this also is tied into Gravitinos, as super partners to Gravitons, as counted by N, initially, and dying out as up to the present day values. From the present, we have the Machian condition of setting, the present condition, as given by Mishra , with being the mass of a sub-system inside the universe, with N being the number of “particles”, and m being the net particle mass. We examine the consequences of Mach’s principle for the case of the mass M, contributing to GW and entropy with a case of , i.e. the total mass of the electro weak era is about the same as today’s mass, but if we look directly at the influence of SUSY physics super partners, in such a way that and there is then an equivalence between SUSY dominated early conditions and non-SUSY as equal to a constant value. i.e. if Machian physics held from early times, up to the present, it would have implications for explaining entropy, as given in, as to why it would be so much lower as of about and before the electro-weak regime than today. This leads to Equations (37)-(39) as hij values to be detected by appropriate GW detectors. 展开更多

On several levels of theoretical physics, especially particle physics and early universe cosmology, de Sitter space-time has become an attractive possibility. The principle of local gauge invariance governs all known fundamental interactions of elementary particles, from electromagnetism and weak interactions to strong interactions and gravity. This paper presents a procedure for defining the gauge-covariant derivative and gauge invariant Lagrangian densityin de Sitter ambient space-time formalism. The gauge invariant field equation is then explicitly calculated in detailfor a massless spit 3/2gauge field. 展开更多

Motivated by the simple toroidal compactification of extra-dimensional SUSY theories, we investigate a partial N =2 supersymmetric(SUSY) extension of the standard model which has an N =2 SUSY sector and an N =1 SUSY sector. We point out that below the scale of the partial breaking of N = 2 to N = 1, the ratio of Yukawa to gauge couplings embedded in the original N =2 gauge interaction in the N =2 sector becomes greater due to a fixed point. Since at the partial breaking scale the sfermion masses in the N = 2 sector are suppressed due to the N = 2 non-renormalization theorem, the anomaly mediation effect becomes important. If dominant, the anomaly-induced masses for the sfermions in the N = 2 sector are almost UV-insensitive due to the fixed point. Interestingly, these masses are always positive, i.e. there is no tachyonic slepton problem. From an example model, we show interesting phenomena differing from ordinary MSSM. In particular, the dark matter particle can be a sbino, i.e. the scalar component of the N = 2 vector multiplet of U(1)_Y. To obtain the correct dark matter abundance, the mass of the sbino, as well as the MSSM sparticles in the N =2 sector which have a typical mass pattern of anomaly mediation, is required to be small. Therefore, this scenario can be tested and confirmed in the LHC and may be further confirmed by the measurement of the N = 2 Yukawa couplings in future colliders. This model can explain dark matter, the muon g-2 anomaly, and gauge coupling unification, and relaxes some ordinary problems within the MSSM. It is also compatible with thermal leptogenesis. 展开更多
