Measuring the top quark mass with m_T2 at the LHC
Won Sang Cho, Kiwoon Choi, Yeong Gyun Kim +1
We investigate the possibility to measure the top quark mass using the collider variable at the LHC experiment. Monte Carlo studies of are performed with the even…
Neutralino dark matter from heavy axino decay
Ki-Young Choi, Jihn E. Kim, Hyun Min Lee +1
We consider cosmological consequences of a heavy axino, decaying to the neutralino in R-parity conserving models. The importance and influence of the axino decay on the resultant a…
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…
