Abstract

A strong follow up of a previous proposal (ICHEP, Valencia 2014) is made leading to the first experiment to observe the gravitational waves at the collision sites at the colliders such as the Large Hadron Collider at CERN. The amplitudes have been calculated with regard to the sensitivity of the detector. Compared with the standard model physics, it is shown to have a measurable impact on the particle motions and corresponds to ‘missing’ energy in form of the gravitational wave loss. This is unlike the cosmological detectors like BICEP2 etc. where the indirect B mode polarization on CMBR were masked by dust. In contrast, this experiment would be the first experiment where the energy-momentum tensor of the source can be controlled.

Highlights

As we cannot control the source conditions or en-route parameters, we have little to experiment with. This gives a reason to think in terms of a future experiment that can be done with the colliders where at the highest energy collision sites the events, though extremely small on energy scales compared with the cosmic mergers, are located at the distances extremely close compared with their cosmic counterparts
Recent acceleration produces its own gravitational waves (GW) superposed on the primordial GW generated by the inflation
Under the planned energy scales of [16-18] TeV in Run 2 of the Large Hadron Collider, the highest to date, it could be a potential site for production and observation of GW due to associated tensor perturbations in spacetime

Summary

The Lagrangian can be splitted with pressure and energy density as

It is seen from (2) and (3) that the inclusion of radiation in tachyonic scalar field gives rise to appearance of new exotic component (with negative energy density and zero pressure).
