Measuring superparticle masses at hadron collider using the transverse mass kink
Won Sang Cho, Kiwoon Choi, Yeong Gyun Kim +1
We present a detailed study of the collider observable applied for pair-produced superparticles decaying to visible particles and a pair of invisible lightest supersymmetr…
Determining Reheating Temperature at Colliders with Axino or Gravitino Dark Matter
Ki-Young Choi, Leszek Roszkowski, Roberto Ruiz de Austri
After a period of inflationary expansion, the Universe reheated and reached full thermal equilibrium at the reheating temperature T_R. In this work we point out that, in the contex…
Gluino Stransverse Mass
Won Sang Cho, Kiwoon Choi, Yeong Gyun Kim +1
We introduce a new observable, 'gluino stransverse mass', which is an application of the Cambridge variable to the process where gluinos are pair produced in proton-proton…
Probing the Messenger of SUSY Breaking with Gaugino Masses
Won Sang Cho, Kiwoon Choi
Gaugino masses might provide useful information on the underlying scheme of supersymmetry breaking as they are least dependent on the unknown physics between the TeV scale and the…
SUSY Breaking at the Tip of Throat and Mirage Mediation
Kiwoon Choi
We discuss some features of supersymmetry breaking induced by a brane-localized source which is stabilized at the IR end of warped throat, and also the resulting mirage mediation p…
Multiple scalar particle decay and perturbation generation
Ki-Young Choi, Jinn-Ouk Gong
We study the evolution of the universe which contains a multiple number of non-relativistic scalar fields decaying into both radiation and pressureless matter. We present a powerfu…
