Theoretical Results

Rotating magnetic fields (RMF) have been used successfuly to drive steady currents in plasmas in many experiments. Some recent experimental and theoretical results did not seem to agree with the standard model based on assuming that the electrons are 'tied' to the lines of the RMF. A more general model based on the concept of flux preserving motion is developed in this paper. It appears that this model provides a unified approach for predicting the qualitative features of RMF current drive under a variety of conditions.

General Relativity (GR) and the Standard Model (SM) of particle physics are two enormously successful frameworks for our understanding the fundamental laws of nature. However, these theoretical schemes are widely disconnected, logically independent and unrelated in scope. Yet, GR and SM at some point must intersect, producing claims about phenomena that should be reconciled. Be it as it may, both schemes share a common basic ground: symmetry under local Lorentz transformations. Here, we will focus on the consequences of assuming this feature from the beginning to combine geometry, matter fields and gauge interactions. We give a rough description of how this could be instrumental for the construction of a unified scheme of gravitation and particle physics.

Generic Group Model

A set of attributes instead of a single string to represent the signer’s identity is a challenging problem under standard cryptographic assumption in the standard model. Therefore, designing a fully secure (adaptive-predicate unforgeable and perfectly private) Attribute-Based Signature (ABS) that allows a signer to choose a set of attributes is vital. Existing schemes are either too complicated or have only been proved in the generic group model. In this chapter, the authors present an efficient fully secure ABS scheme in the standard model based on q-parallel BDHE assumption, which is more practical than the generic group model used in the previous schemes. The proposed scheme is highly expressive since it allows any signer to specify claim-predicates in terms of any predicate consisting of AND, OR, and Threshold gates over the attributes in the system. ABS has found many important applications in secure communications, such as anonymous authentication systems and attribute-based messaging systems.

This brief work tenets that inflationary genesis can be obtained within the standard model based on only a few general assumptions. These are that the origin began at a singularity of Planck length and that all quantum transitions take place within Planck time units. From these, the subsequent effects from the Pauli Exclusion Principle (PEP) and the uncertainty principle can then give rise to an inflationary origin.

Family Models

We carry out a systematic study of possible extensions of the standard model based on the gauge group SU (3)c⊗ SU (4)L⊗ U (1)X. We consider models with particles having exotic electric charges and also models which do not contain exotic electric charges in the gauge boson sector or in the fermion sector. For the first case an infinite number of models can, in principle, be constructed, while the restriction to non-exotic electric charges only allows for eight different anomaly-free models. Four of them are three-family models in the sense that anomalies cancel by an interplay between the three families, and another two are one-family models where anomalies cancel family by family as in the standard model. The remaining two are two-family models.

We consider extensions of the Standard Model based on open strings ending on D-branes, with gauge bosons due to strings attached to stacks of D-branes and chiral matter due to strings stretching between intersecting D-branes. Assuming that the fundamental string mass scale is in the TeV range and the theory is weakly coupled, we discuss possible signals of string physics at the Large Hadron Collider (LHC).

The Standard Model

We examine the phenomenology of a low-energy extension of the Standard Model, based on the gauge group SU (3) ⊗ SU (2) ⊗ U (1)⊗ SO (3), with SO(3) operating in the shadow sector. This model offers vacuum νe → νs and νμ → ντ oscillations as the solution of the solar and atmospheric neutrino problems, and it provides a neutral heavy shadow lepton X that takes the role of a cold dark matter particle.
