On Proper Time in General Relativity
M. Özer, M. O. Taha
It is shown how the relation between the proper distance and the proper time is obtained in general relativity. A general relation in curved spacetime between …
A Non-Singular Universe in String Cosmology
A. A. Al-Nowaiser, Murat Özer, M. O. Taha
We consider the low-energy effective string action in four dimensions including the leading order- terms. An exact homogeneous solution is obtained. It represents a non-singula…
Spontaneous Decay of the Effective Cosmological Constant
Murat Özer, M. O. Taha
We discuss the notion that quantum fields may induce an effective time-dependent cosmological constant which decays from a large initial value. It is shown that such cosmological m…
An Upper Bound on the Higgs Boson Mass from a Positivity Condition on the Mass Matrix
Ali Al-Naghmoush, Murat Özer, M. O. Taha
We impose the condition that the eigenvalues of the mass matrix in the shifted Lagrangian density be positive at ϕ=ϕ_{0}, the vacuum expectation value of the scalar field. Using th…
