Determining Reheating Temperature at LHC 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. In this talk, based on the paper, arXiv:0710.3349…
M_T2-assisted on-shell reconstruction of missing momenta and its application to spin measurement at the LHC
Won Sang Cho, Kiwoon Choi, Yeong Gyun Kim +1
We propose a scheme to assign a 4-momentum to each WIMP in new physics event producing a pair of mother particles each of which decays to an invisible weakly interacting massive pa…
Moduli stabilization and the pattern of sparticle spectra
Kiwoon Choi
We discuss the pattern of low energy sparticle spectra which appears in some class of moduli stabilization scenario. In case that light moduli are stabilized by non-perturbative ef…
Flavor and CP conserving moduli mediated SUSY breaking in flux compactification
Kiwoon Choi, Kwang Sik Jeong, Ken-Ichi Okumura
In certain class of flux compactification, moduli mediated supersymmetry (SUSY) breaking preserves flavor and CP at leading order in the perturbative expansion controlled by the va…
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…
