Lepton Number Violation and W' Chiral Couplings at the LHC
Tao Han, Ian Lewis, Richard Ruiz +1
We study the observability for a heavy Majorana neutrino N along with a new charged gauge boson W' at the LHC. We emphasize the complementarity of these two particles in their prod…
Potential precision of a direct measurement of the Higgs boson total width at a muon colliderr
Tao Han, Zhen Liu
In the light of the discovery of a 126 GeV Standard-Model-like Higgs boson at the LHC, we evaluate the achievable accuracies for direct measurements of the width, mass, and the s-c…
Kinematic Cusps with Two Missing Particles II: Cascade Decay Topology
Tao Han, Ian-Woo Kim, Jeonghyeon Song
Three-step cascade decays into two invisible particles and two visible particles via two intermediate on-shell particles develop cusped peak structures in several kinematic distrib…
Kinematic Cusps With Two Missing Particles I: Antler Decay Topology
Tao Han, Ian-Woo Kim, Jeonghyeon Song
The kinematics of a final state system with two invisible particles and two visible particles can develop cusped peak structures. This happens when the system has a fixed invariant…
New Physics from the Top at the LHC
Chien-Yi Chen, Ayres Freitas, Tao Han +1
The top quark may hold the key to new physics associated with the electroweak symmetry-breaking sector, given its large mass and enhanced coupling to the Higgs sector. We systemati…
Pair Production of MSSM Higgs Bosons in the Non-decoupling Region at the LHC
Neil D. Christensen, Tao Han, Tong Li
We consider the Higgs boson signals from pair production at the LHC within the framework of the MSSM in the non-decoupling (low-m_A) region. In light of the recent observation of a…
