Higgs boson production in photon-photon collision at ILC: a comparative study in different little Higgs models

Lei Wang, Fuqiang Xu, Jin Min Yang

We study the process γγ->h->bb_bar at ILC as a probe of different little Higgs models, including the simplest little Higgs model (SLH), the littlest Higgs model (LH), and two types…

W_L W_L Scattering in Higgsless Models: Identifying Better Effective Theories

Alexander S. Belyaev, R. Sekhar Chivukula, Neil D. Christensen +4

The three-site model has been offered as a benchmark for studying the collider phenomenology of Higgsless models. In this paper we analyze how well the three-site model performs as…

Computation of the p6 order chiral Lagrangian coefficients from the underlying theory of QCD

Shao-Zhou Jiang, Ying Zhang, Chuan Li +1

We present results of computing the p6 order low energy constants in the normal part of chiral Lagrangian both for two and three flavor pseudo-scalar mesons. This is a generalizati…

Double Type-II Seesaw, Baryon Asymmetry and Dark Matter for Cosmic e^\pm Excesses

Pei-Hong Gu, Hong-Jian He, Utpal Sarkar +1

We construct a new realization of type-II seesaw for neutrino masses and baryon asymmetry by extending the standard model with one light and two heavy singlet scalars besides one H…

Derivation of Electroweak Chiral Lagrangian from One Family Technicolor Model

Hong-Hao Zhang, Kai-Xi Feng, Shao-Zhou Jiang +1

Based on previous studies deriving the chiral Lagrangian for pseudo scalar mesons from the first principle of QCD in the path integral formalism, we derive the electroweak chiral L…

Z' Boson Mixings with Z-γand Charge Assignments

Ying Zhang, Qing Wang

Based on the general description for Z'-Z-γmixing as derived from the electroweak chiral Lagrangian, we characterize and classify the various new physics models involving the Z' bo…

Pion Superfluidity beyond Mean Field Approximation In Nambu--Jona-Lasinio Model

Chengfu Mu, Pengfei Zhuang

We investigate pion superfluidity in the frame of two flavor Nambu--Jona-Lasinio model beyond mean field approximation. We calculate the thermodynamics to the next to leading order…

Electroweak Chiral Lagrangian for a Hypercharge-universal Topcolor Model

Jun-Yi Lang, Shao-Zhou Jiang, Qing Wang

Electroweak chiral Lagrangian for a hypercharge-universal topcolor model is investigated. We find that the assignments of universal hypercharge improve the results obtained previou…

The Search for Heavy Majorana Neutrinos

Anupama Atre, Tao Han, Silvia Pascoli +1

The Majorana nature of neutrinos can be experimentally verified only via {\it lepton-number} violating processes involving charged leptons. We study 36 lepton-number violating ($\l…
