Strings versus Anti Strings in the inversion invariant or proper volume formulation

E. Guendelman

The specific model studied is in the context of the modified measure formulation the string or branes where tension appear as an additional dynamical degree of freedom . We then co…

Relieving String Tension By Making Baby Universes in a Dynamical String Tension Braneworld Model

Eduardo I. Guendelman, Zeeya Merali

String tension fundamentally determines the properties of strings; yet its value is often assigned arbitrarily, creating a fine-tuning problem. We describe a mechanism for dynamica…

Brane world creation from flat or almost flat space in dynamical tension string theories

E. I. Guendelman, J. Portnoy

There is great interest in the construction of brane worlds, where matter and gravity are forced to be effective only in a lower dimensional surface , the brane . How these could a…

Implications of the Spectrum of Dynamically Generated String Tension Theories

E. I. Guendelman

The string tension does not have to be put in by hand, it can be dynamically generated, as in the case when we formulate string theory in the modified measure formalism, and other…

Dynamical String Tension Theories with target space scale invariance SSB and restoration

Eduardo Guendelman

The string and brane tensions do not have to be put in by hand, they can be dynamically generated, as in the case when we formulate string and brane theories in the modified measur…

A Born-Infeld Scalar and a Dynamical Violation of the Scale Invariance from the Modified Measure Action

T. O. Vulfs, E. I. Guendelman

Starting with a simple two scalar field system coupled to a modified measure that is independent of the metric, we, first, find a Born-Infeld dynamics sector of the theory for a sc…

Modified Gravity and Inflaton Assisted Dynamical Generation of Charge Confinement and Electroweak Symmetry Breaking in Cosmology

Eduardo Guendelman, Emil Nissimov, Svetlana Pacheva

We describe a new type of gravity-matter models where modified f(R)=R+R^2 gravity couples non-canonically to a scalar "inflaton", to the bosonic sector of the electroweak particle…

Gauge theory of Gravity based on the correspondence between the and the order formalisms

David Benisty, Eduardo I. Guendelman, Jurgen Struckmeier

This is a shortened version of an invited talk at the XIII International Workshop "Lie Theory and its Applications in Physics", June 17-23, Varna, Bulgaria. A covariant canonical g…

String Model with Mesons and Baryons in Modified Measure Theory

T. O. Vulfs, E. I. Guendelman

We consider string meson and string baryon models in the framework of the modified measure theory, the theory that does not use the determinant of the metric to construct the invar…

Superstrings with the Galileon Measure

T. O. Vulfs, E. I. Guendelman

The modified measure theories recommend themselves as a good possibility to go beyond the standard formulation to solve yet unsolved problems. The Galileon measure that is construc…

Galileon string measure and other modified measure extended objects

T. O. Vulfs, E. I. Guendelman

We show that it is possible to formulate string theory as a "Galileon string theory". The galileon field enters in the definition of the integration measure in the action. Foll…

Gravity-Assisted Emergent Higgs Mechanism in the Post-Inflationary Epoch

Eduardo Guendelman, Emil Nissimov, Svetlana Pacheva

We consider a non-standard model of gravity coupled to a neutral scalar "inflaton" as well as to SU(2)xU(1) iso-doublet scalar with positive mass squared and without self-interacti…

Consistent gauge interaction involving dynamical coupling and anomalous current

Eduardo. I. Guendelman, Roee Steiner

We show a possible way to construct a consistent formalism where the effective electric charge can change with space and time without destroying the invariance. In the previous wor…

Bag Formation from Gauge Condensate

Mahary Vasihoun, Eduardo Guendelman

As it is well known, one can lower the energy of the trivial perturbation QCD vacuum by introducing a non-vanishing chromomagnetic field strength. This happens because radiative co…
