The Decay of a Black Hole in a GUT Model  [PDF]
Risto Raitio
Open Access Library Journal (OALib Journal) , 2015, DOI: 10.4236/oalib.1102031
Abstract: I propose a phenomenological model for the decay of black holes near Planck mass. The decay takes place via a quantum state between general relativity and a grand unified field theory like SO(10). This group is favored also by a no-scale SUGRA GUT model for Starobinsky inflation by other authors.
Why and How Do Black Holes Radiate?  [PDF]
Risto Raitio
Open Access Library Journal (OALib Journal) , 2015, DOI: 10.4236/oalib.1102254
Abstract: The phenomenological model proposed in this note indicates that the black hole radiation consists of two components: the standard thermal Hawking radiation and an additional non-thermal baryonic/leptonic component due to quantum number neutralization by the no-hair theorem. The particle radiation grows relatively stronger than the Hawking radiation with increasing black hole mass, and it can be tested in principle.
A Statistical Model of Spacetime, Black Holes and Matter  [PDF]
Risto Raitio
Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1102487
Abstract: I propose first a simple model for quantum black holes based on a harmonic oscillator representing the black hole horizon covered by Planck length sized squares carrying soft hair. Secondly, I redefine the partition function sum over horizon squares by a sum over black hole stretched horizon constituents which are black holes themselves. From this partition function Hawking radiation and Bekenstein-Hawking entropy law have been predicted. Based on this model I propose that the structures of black holes and spacetime atoms are the same. Requiring consistent quantization for both spacetime and matter, black hole structure is considered for matter particles using a composite model for quarks and leptons.
Standard Model Matter Emerging from Spacetime Preons  [PDF]
Risto Raitio
Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1102788
Abstract:
I consider a statistical mechanical model for black holes as atoms of spacetime with the partition function sum taken over area eigenvalues as given by loop quantum gravity. I propose a unified structure for matter and spacetime by applying the area eigenvalues to a black hole composite model for quarks and leptons. Gravitational baryon number’s non-conservation mechanism is predicted. Argument is given for unified field theory based on gravitational and electromagnetic interactions only. The standard model of non-Abelian gauge interactions is briefly discussed.
Combinatorial Preon Model for Matter and Unification  [PDF]
Risto Raitio
Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1103032
Abstract:
I consider a preon model for quarks and leptons based on constituents defined by mass, spin and charge. The preons form a finite combinatorial system for the standard model fermions. The color and weak interaction gauge structures can be deduced from the preon bound states. By applying the area eigenvalues of loop quantum gravity to black hole preons, one gets a preon mass spectrum starting from zero. Gravitational baryon number non-conservation mechanism is obtained. Argument is given for unified field theory is based only on gravitational and electromagnetic interactions of preons.
A Conformal Preon Model  [PDF]
Risto Raitio
Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1103262
Abstract:
I consider a preon model for quarks and leptons based on massless constituents having spin 1/2 and charge 1/3 or 0. The color and weak interaction gauge structures can be deduced from the three preon states. Argument is given for unified field theory being based on gravitational and electromagnetic interactions only. Conformal symmetry is introduced in the action of gravity with the Weyl tensor. Electromagnetism is geometrized to conform with gravity. Baryon number non-conservation mechanism is obtained.
On the Conformal Unity between Quantum Particles and General Relativity  [PDF]
Risto Raitio
Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103342
Abstract:
I consider the standard model, together with a preon version of it, to search for unifying principles between quantum particles and general relativity. Argument is given for unified field theory being based on gravitational and electromagnetic interactions alone. Conformal symmetry is introduced in the action of gravity with the Weyl tensor. Electromagnetism is geometrized to conform with gravity. Conformal symmetry is seen to improve quantization in loop quantum gravity. The Einstein-Cartan theory with torsion is analyzed suggesting structure in spacetime below the Cartan scale. A toy model for black hole constituents is proposed. Higgs metastability hints at cyclic conformal cosmology.
Preon Model, Knot Algebra and Gravity  [PDF]
Risto Raitio
Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103432
Abstract:
I study the properties of a preon model for the substructure of the standard model quarks and leptons. The goal is to establish both local and global group representations for the particles of the model. Knot theory algebra SLq(2) is shown to be applicable to the model. Teleparallel gravity is discussed with an interesting result to hadronic physics. A tentative glimpse on quantum gravity is indicated.
Preons, Standard Model, Gravity with Torsion and Black Holes  [PDF]
Risto Raitio
Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103632
Abstract:
A previous spin 1/2 preon model for the substructure of the standard model quarks and leptons is complemented to provide particle classification group, preon interactions and a tentative model of black holes. The goal of this study is to analyze a phenomenological theory of all interactions. A minimal amount of physical assumptions are made and only experimentally verified global and gauge groups are employed: SLq(2), the three of the standard model and the full Poincaré group. Gravity theory with torsion is introduced producing an axial-vector field coupled to preons. The mass of the axial-vector particle is estimated to be near the GUT scale. The boson can materialize above this scale and gain further mass to become a black hole at Planck mass while massless preons may form the horizon. A particle-black hole duality is proposed.
Preons, Gravity and Black Holes  [PDF]
Risto Raitio
Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103784
Abstract:
A previous preon model for the substructure of the standard model quarks and leptons is completed to provide a model of Planck scale gravity and black holes. Gravity theory with torsion is introduced in the model. Torsion has been shown to produce an axial-vector field coupled to spinors, in the present case preons, causing an attractive preon-preon interaction. This is assumed to be the leading term of UV gravity. The boson has an estimated mass near the Planck scale. At high enough density it can materialize and become the center of a black hole. Chiral phase preons are proposed to form the horizon with thickness of order of Planck length. Using quantum information theoretic concepts this is seen to lead to an area law of black hole entropy.
