Cosmological gravitino problem confronts electroweak physics
Gi-Chol Cho, Yosuke Uehara
A generic feature of gauge-mediated supersymmetry breaking models is that the gravitino is the lightest supersymmetric particle (LSP). In order not to overclose the universe, the g…
Black Holes at the LHC can Determine the Spin of Higgs Bosons
Yosuke Uehara
We propose a new method to determine the spin of Higgs bosons at the LHC by using the decay products of black holes. Black holes may be produced if TeV-scale gravity theories are c…
Neutrino Majorana Mass from Black Hole
Yosuke Uehara
We propose a new mechanism to generate the neutrino Majorana mass in TeV-scale gravity models. The black hole violates all non-gauged symmetries and can become the origin of lepton…
New Potential of Black Holes : Quest for TeV-Scale Physics by Measuring Top Quark Sector using Black Holes
Yosuke Uehara
If TeV-scale gravity models are correct, the production of black holes will be the first signal of new physics. Once black holes are produced, they will give us much information ab…
Virtual Black Holes at Linear Colliders
Yosuke Uehara
We propose that future linear colliders can create virtual black holes even though their energies are below the fundamental scale, because of the uncertainty principle. These virtu…
Measuring the Spin of Invisible Massive Graviton Excitations at Future Linear Colliders
E. Asakawa, K. Odagiri, Y. Uehara
We consider the production process e-e+ -> Gγof invisible gravitons (G) at future linear colliders. We discuss whether the angular distribution of the photon (γ) can be used to mea…
