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…
Vibrationally induced flip motion of a hydroxyl dimer on Cu(110)
Yasuhiro Ootsuka, Thomas Frederiksen, Hiromu Ueba +1
Recent low-temperature scanning-tunneling microscopy experiments [T. Kumagai et al., Phys. Rev. B 79, 035423 (2009)] observed the vibrationally induced flip motion of a hydroxyl di…
First-order electroweak phase transition powered by additional F-term loop effects in an extended supersymmetric Higgs sector
Shinya Kanemura, Eibun Senaha, Tetsuo Shindou
We investigate the one-loop effect of new charged scalar bosons on the Higgs potential at finite temperatures in the supersymmetric standard model with four Higgs doublet chiral su…
Testing the Higgs triplet model with the mass difference at the LHC
Mayumi Aoki, Shinya Kanemura, Kei Yagyu
In general, there can be mass differences among scalar bosons of the Higgs triplet field with the hypercharge of Y=1. In the Higgs triplet model, when the vacuum expectation value…
Parity Violation in QCD Process
Naoyuki Haba, Kunio Kaneta, Shigeki Matsumoto +2
Parity violation in QCD process is studied using helicity dependent top quark pair productions at Large Hadron Collider experiment. Though no violation can be found in the standard…
Indirect bounds on heavy scalar masses of the two-Higgs-doublet model in light of recent Higgs boson searches
Shinya Kanemura, Yasuhiro Okada, Hiroyuki Taniguchi +1
We study an upper bound on masses of additional scalar bosons from the electroweak precision data and theoretical constraints such as perturbative unitarity and vacuum stability in…
