Multi-tau-lepton signatures at the LHC in the two Higgs doublet model
Shinya Kanemura, Koji Tsumura, Hiroshi Yokoya
A detailed simulation study is performed for multi-tau-lepton signatures at the Large Hadron Collider, which can be used to probe additional Higgs bosons with lepton-specific Yukaw…
Color-octet scalars and potentially large CP violation at the LHC
Xiao-Gang He, German Valencia, Hiroshi Yokoya
We consider the phenomenology of CP violation in a color-octet extended scalar sector for t\bar{t} production and decay at the LHC. In particular we study the effect of the two neu…
Early LHC Phenomenology of Yukawa-bound Heavy Q\bar{Q} Mesons
Tsedenbaljir Enkhbat, Wei-Shu Hou, Hiroshi Yokoya
Current limits from the LHC on fourth generation quarks are already at the unitarity bound of 500 GeV or so. If they exist, the strong Yukawa couplings are turning nonperturbative,…
Boost-invariant Leptonic Observables and Reconstruction of Parent Particle Mass
Sayaka Kawabata, Yasuhiro Shimizu, Yukinari Sumino +1
We propose a class of observables constructed from lepton energy distribution, which are independent of the velocity of the parent particle if it is scalar or unpolarized. These ob…
Colored Scalars And The CDF dijet Excess
Tsedenbaljir Enkhbat, Xiao-Gang He, Yukihiro Mimura +1
The recent data on dijet excess reported by CDF may be interpreted as the associated production of a and a new particle of mass about 150 GeV which subsequently decays into…
Measuring the top Yukawa coupling at the ILC at sqrt(s) = 500 GeV
Ryo Yonamine, Katsumasa Ikematsu, Tomohiko Tanabe +4
We report on the feasibility of the direct measurement of the top Yukawa coupling g_t at the International Linear Collider (ILC) during its first phase of operation with a center-o…
