Signals of a superlight gravitino at the LHC
Fabio Maltoni, Antony Martini, Kentarou Mawatari +1
Very light gravitinos could be produced at a sizeable rate at colliders and have been searched for in the mono-photon or mono-jet plus missing momentum signature. Strategies for en…
Monophoton signals in light gravitino production at colliders
Kentarou Mawatari, Bettina Oexl
We revisit the monophoton plus missing energy signature at colliders in supersymmetric (SUSY) models where the gravitino is very light. There are two possible processes wh…
Simulating spin-3/2 particles at colliders
Neil D. Christensen, P. de Aquino, N. Deutschmann +7
Support for interactions of spin-3/2 particles is implemented in the FeynRules and ALOHA packages and tested with the MadGraph 5 and CalcHEP event generators in the context of thre…
Light gravitino production in association with gluinos at the LHC
P. de Aquino, F. Maltoni, K. Mawatari +1
We study the jets plus missing energy signature at the LHC in a scenario where the gravitino is very light and the gluino is the next-to-lightest supersymmetric particle and prompt…
Associated production of light gravitinos in e^+e^- and e^-γcollisions
K. Mawatari, B. Oexl, Y. Takaesu
Light gravitino productions in association with a neutralino (selectron) in e^+e^- (e^-γ) collisions are restudied in a scenario that the lightest supersymmetric particle is a grav…
Radiative decays of double heavy baryons in a relativistic constituent three-quark model including hyperfine mixing
Tanja Branz, Amand Faessler, Thomas Gutsche +4
We study flavor-conserving radiative decays of double heavy baryons using a manifestly Lorentz covariant constituent three-quark model. Decay rates are calculated and compared to e…
