The LHCb collaboration has reported an intriguing new result in its quest to test a key principle of the Standard Model called lepton universality. Although not statistically significant, the finding ...
Universality of the self gravitational potential energy of any fundamental particle
Cosmology quantum mechanics gravitational energy cosmological scale factor Weinbergs relation
2011/8/4
Abstract: Using the relation proposed by Weinberg in 1972, combining quantum and cosmological parameters, we prove that the self gravitational potential energy of any fundamental particle is a quantum...
Proof of universality of electrical conductivity at finite chemical potential
electrical conductivity finite chemical potential
2010/12/23
It was proposed in arXiv:1008.2944 that, for certain gauge theories with gravity duals, electrical conductivity at finite chemical potential is universal. Here we provide a general proof that, when m...
Uniform density static fluid sphere in higher dimensions and its universality
spacetime dimension uniform density sphere
2010/3/18
In Newtonian theory, gravity inside a constant density static sphere is independent of spacetime dimension. Interestingly this general result is also carried over to Einsteinian as well as higher orde...
