Higgs inflation in a radiative seesaw model
Shinya Kanemura, Toshinori Matsui, Takehiro Nabeshima
We investigate a simple model to explain inflation, neutrino masses and dark matter simultaneously. This is based on the so-called radiative seesaw model proposed by Ma in order to…
Radiative type-I seesaw model with dark matter via U(1)_{B-L} gauge symmetry breaking at future linear colliders
Shinya Kanemura, Takehiro Nabeshima, Hiroaki Sugiyama
We discuss phenomenology of the radiative seesaw model in which spontaneous breaking of the U(1) gauge symmetry at the TeV scale gives the common origin for masses of neutr…
Higgs portal dark matter at a linear collider
Takehiro Nabeshima
We investigate the possibility of detecting dark matter at TeV scale linear colliders in the scenario where the dark matter interacts with standard model particles only via the Hig…
TeV-Scale Seesaw with Loop-Induced Dirac Mass Term and Dark Matter from U(1)_{B-L} Gauge Symmetry Breaking
Shinya Kanemura, Takehiro Nabeshima, Hiroaki Sugiyama
We show a TeV-scale seesaw model where Majorana neutrino masses, the dark matter mass, and stability of the dark matter can be all originated from the U(1)_{B-L} gauge symmetry. Di…
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…
A Simple Method of Calculating Effective Operators
N. Haba, K. Kaneta, S. Matsumoto +1
It is important to obtain effective operators by integrating out high energy degrees of freedom in physics. We suggest a general method of calculating accurate irrelevant operators…
