Studies of exotic hadrons by high-energy exclusive reactions
H. Kawamura, S. Kumano, T. Sekihara
We investigate the possibility of clarifying internal structure of exotic hadrons by high-energy exclusive reactions. In particular, the constituent-counting rule could be used for…
Physics Reach of Atmospheric Neutrino Measurements at PINGU
Shao-Feng Ge, Kaoru Hagiwara
The sensitivity of a huge underground water/ice Cherenkov detector, such as PINGU in IceCube, to the neutrino mass hierarchy, the atmospheric mixing angle and its octant, is studie…
Measurement of Higgs couplings and self-coupling at the ILC
Junping Tian, Keisuke Fujii
In the Standard Model (SM) the couplings of the Higgs boson to SM particles and itself (self-couplings) are uniquely specified once the masses of the particles in question as well…
Gravitino thermal production revisited and a new cosmological scenario of gauge mediation
Hiraku Fukushima, Ryuichiro Kitano
We present a new scenario of gravitino dark matter which is compatible with the thermal leptogenesis. We confirm by an explicit calculation in supergravity that the relic abundance…
Higgs Production in Two-Photon Process and Transition Form Factor
Norihisa Watanabe, Yoshimasa Kurihara, Ken Sasaki +1
The Higgs production in the two-photon fusion process is investigated where one of the photons is off-shell while the other one is on-shell. This process is realized in either elec…
Muon g-2 and LHC phenomenology in the gauge symmetric model
Keisuke Harigaya, Takafumi Igari, Mihoko M. Nojiri +2
In this paper, we consider phenomenology of a model with an gauge symmetry. Since the muon couples to the gauge boson (called boson), its contribution to…
Composite Higgsino
Masaki Asano, Ryosuke Sato
Several supersymmetric models in which there is a (partially) composite Higgs boson arising from (coupled to) a strong sector have been proposed. Such strong dynamics would help to…
Gauge invariant Barr-Zee type contributions to fermionic EDMs in the two-Higgs doublet models
Tomohiro Abe, Junji Hisano, Teppei Kitahara +1
We calculate all gauge invariant Barr-Zee type contributions to fermionic electric dipole moments (EDMs) in the two-Higgs doublet models (2HDM) with softly broken Z2 symmetry. We s…
Decays of Zb -> Upsilon + pi via triangle diagrams in heavy meson molecules
Shunsuke Ohkoda, Shigehiro Yasui, Atsushi Hosaka
Bottomonium-like resonances Zb(10610) and Zb'(10650) are good candidates of hadronic molecules composed of BBbar* (or B*Bbar) and B*Bbar*, respectively. Considering Zb (Zb') as hea…
Higgs boson signal at complete tree level in the SM extension by dimension-six operators
E. Boos, V. Bunichev, M. Dubinin +1
Deviations from the standard Higgs sector generated by some new (nonstandard) physics at an energy scale Λcould be described by an effective SU(3)_c x SU(2)_L x U(1) invariant non-…
Radiative symmetry breaking at the Fermi scale and flat potential at the Planck scale
Michio Hashimoto, Satoshi Iso, Yuta Orikasa
We investigate a possibility of the "flatland scenario", in which the electroweak gauge symmetry is radiatively broken via the Coleman-Weinberg mechanism starting from a completely…
Effective gravitational interactions of dark matter axions
Toshifumi Noumi, Ken'ichi Saikawa, Ryosuke Sato +1
We investigate the structure of gravitational self-interactions of coherently oscillating axions in the general relativistic framework. A generic action for a massive scalar field…
Microscopic identification of dissipative modes in relativistic field theories
Yohei Saito, Hirotsugu Fujii, Kazunori Itakura +1
We present an argument to support the existence of dissipative modes in relativistic field theories. In an O(N) theory in spatial dimension , a relaxation constant $Γ…
A UV complete model for radiative seesaw and electroweak baryogenesis based on the SUSY gauge theory
Shinya Kanemura, Naoki Machida, Tetsuo Shindou +1
In a class of supersymmetric gauge theories with asymptotic freedom, the low energy effective theory below the confinement scale is described by the composite superfields of the fu…
One loop integration with hypergeometric series by using recursion relations
Norihisa Watanabe, Toshiaki Kaneko
General one-loop integrals with arbitrary mass and kinematical parameters in -dimensional space-time are studied. By using Bernstein theorem, a recursion relation is obtained wh…
A first evidence of the CMSSM is appearing soon
Yasufumi Konishi, Shingo Ohta, Joe Sato +3
We explore the coannihilation region of the constrained minimal supersymmetric standard model (CMSSM) being consistent with current experimental/observational results. The requirem…
Phenomenological Study of Residual Z^s_2 and Zbar^s_2 Symmetries
Andrew D. Hanlon, Shao-Feng Ge, Wayne W. Repko
The phenomenological consequences of the residual Z^s_2 and Zbar^s_2 symmetries are explored in detail. With a precisely measured value of the reactor angle, these two residual sym…
Hilltop Supernatural Inflation and SUSY Unified Models
Kazunori Kohri, C. S. Lim, Chia-Min Lin +1
In this paper, we consider high scale (100 TeV) supersymmetry (SUSY) breaking and realize the idea of hilltop supernatural inflation in concrete particle physics models based on fl…
A Novel Approach to Study Atmospheric Neutrino Oscillation
Shao-Feng Ge, Kaoru Hagiwara, Carsten Rott
We develop a general theoretical framework to analytically disentangle the contributions of the neutrino mass hierarchy, the atmospheric mixing angle, and the CP phase, in neutrino…
Future sensitivity to new physics in B_d, B_s and K mixings
Jerome Charles, Sebastien Descotes-Genon, Zoltan Ligeti +3
We estimate, in a large class of scenarios, the sensitivity to new physics in B_d and B_s mixings achievable with 50 ab-1 of Belle II and 50 fb-1 of LHCb data. We find that current…

Yasuhito Sakaki, Minoru Tanaka, Andrey Tayduganov +1
We study potential New Physics effects in the decays. As a particular example of New Physics models we consider the class of leptoquark models and put t…
Determination of exotic hadron structure by constituent-counting rule for hard exclusive processes
Hiroyuki Kawamura, Shunzo Kumano, Takayasu Sekihara
We propose to use hard exclusive production of an exotic hadron for finding its internal quark-gluon configuration by the constituent-counting rule in perturbative QCD. In particul…
10 GeV neutralino dark matter and light stau in the MSSM
Kaoru Hagiwara, Satyanarayan Mukhopadhyay, Junya Nakamura
It has recently been pointed out that a component of the observed gamma ray emission in the low-latitudes of Fermi Bubble has a spectral shape that can be explained by a 10 GeV dar…
Scale-dependent CMB asymmetry from primordial configuration
Kazunori Kohri, Chia-Min Lin, Tomohiro Matsuda
We demonstrate that a topological defect can explain the hemispherical power asymmetry of the CMB. The first point is that a defect configuration, which already exists prior to inf…
