By making random scans over the parameters of the model, we show that there are regions consistent with constraints from collider experiments and the requirement for a strong first-order electroweak phase transition which is needed for electroweak baryogenesis. Further, we also study the power spectrum of the gravitational waves which can be generated due to the first-order phase transitions. Observation of such gravitational waves, such as by future space-b ... 17:00 - 18:00 IPM Holography virtual seminar Cosmic censorship conjecture in a general Kerr–Newman black hole School PARTICLES AND ACCELERATORS Abstract: Using some probes, the violation of cosmic censorship conjecture in a general Kerr–Newman black hole is investigated. The result depends on many factors, like the relative sign of charge and rotation direction of the probe and black hole. Moreover the comparison of the angular momentum of the black hole and its charge has an impressive effect. Considering all these together, we have found the range of the angular momentum, energy and charge of the probe for which the event horizon disappears. We have found that cosmic censorship conjecture violation is possible only for near extremal black hole if the parameters of the probe are too ... |
