# Beyond the Standard Model with sum rules

@article{Ejlli2019BeyondTS, title={Beyond the Standard Model with sum rules}, author={Damian Ejlli}, journal={International Journal of Modern Physics A}, year={2019} }

The possibility of physics beyond the Standard Model is studied. The requirement of finiteness of the zero-point energy density and pressure or the requirement of the Lorentz invariance of the zero-point stress-energy tensor in Minkowski space–time, implies regularization sum rules on the number of degrees of freedom and mass of fundamental particles spectrum. The consequences of these sum rules on the existence of particles beyond the Standard Model are studied. If these sum rules are to be…

Conventional particle theories such as the Standard Model have a number of freely adjustable coupling constants and mass parameters, depending on the symmetry algebra of the local gauge group and the…

Some 67 years ago (1951), Wolfgang Pauli noted that the net zero-point energy density could be set to zero by a carefully fine-tuned cancellation between bosons and fermions. In the current article,…

The conditions for the cancellation of one loop contributions to vacuum energy (both U.V. divergent and finite) coming from the Standard Model (SM) fields are examined. It is proven that this is not…

One hope to solve the cosmological constant problem is to identify a symmetry principle, based on which the cosmological constant can be reduced either to zero, or to a tiny value. Here, we note that…

We propose that gravity be intrinsically quantum-mechanical, so that in the absence of quantum mechanics the geometry of the universe would be Minkowski. We show that in such a situation gravity does…
