Brane-Localized Potential (2009)
Haba, Naoyuki, Oda, Kin-ya, Takahashi, Ryo
We clarify and study our previous observation that, under a compactification with boundaries or orbifolding, vacuum expectation value of a bulk scalar field can have different extra-dimensional...
Invisibly broad Higgs in extra-dimension, consistent with electroweak data (2009)
Haba, Naoyuki, Oda, Kin-ya, Takahashi, Ryo
We propose a simple five-dimensional extension of the Standard Model (SM) without any Higgs potential nor any extra fields. A Higgs doublet lives in the bulk of a flat line segment and its boundary...
Top Yukawa Deviation in Extra Dimension (2009)
Haba, Naoyuki, Oda, Kin-ya, Takahashi, Ryo
We suggest a simple one-Higgs-doublet model living in the bulk of five-dimensional spacetime compactified on $S^1/Z_2$, in which the top Yukawa coupling can be smaller than the naive standard-model...
Kinoshita, Shunichiro, Mukohyama, Shinji, Nakamura, Shin, Oda, Kin-ya
We propose a consistent setup for the holographic dual of the strongly coupled large-Nc N=4 super Yang-Mills theory plasma which undergoes the Bjorken flow relevant to the quark-gluon plasma at BNL...
Smoothing out Negative Tension Brane (2008)
Oda, Kin-ya, Suyama, Takao, Yokoi, Naoto
We propose an extension of the five dimensional gravitational action with an external source in order to allow arbitrary smoothing of the negative tension brane in the Randall-Sundrum model. This...
Geometric cross sections of rotating strings and black holes (2008)
Matsuo, Toshihiro, Oda, Kin-ya
We study the production cross section of a highly excited string with fixed angular momentum from an ultra-high energy collision of two light strings. We find that the cross section exhibits...
A Holographic Dual of Bjorken Flow (2008)
Kinoshita, Shunichiro, Mukohyama, Shinji, Nakamura, Shin, Oda, Kin-ya
We propose a consistent setup for a holographic dual of Bjorken flow of strongly coupled large-Nc N=4 SYM-theory plasma. We employ Eddington-Finkelstein type coordinates for the dual geometry, and we...
Dynamical Rearrangement of Theta Parameter in Presence of Mixed Chern-Simons Term (2008)
Haba, Naoyuki, Kawamura, Yoshiharu, Oda, Kin-ya
We study the five-dimensional SU(3)_c x U(1)_C gauge theory on the orbifold S^1/Z_2 with a mixed Chern-Simons term. We particularly pay attention to the realization of the dynamical rearrangement of...
Orbifold Family Unification (2007)
Kawamura, Yoshiharu, Kinami, Teppei, Oda, Kin-ya
We study the possibility of complete family unification in higher-dimensional space-time. Three families of matters in SU(5) grand unified theory are derived from a single bulk multiplet of SU(N)...
Effects of brane-flux transition on black holes in string theory (2007)
Loaiza-Brito, Oscar, Oda, Kin-ya
Extremal N=2 black holes in four dimensions can be described by an ensemble of D3-branes wrapped on internal supersymmetric three-cycles of Calabi-Yau threefolds on which type IIB superstring theory...
QCD Effects in the Decays of TeV Black Holes (2006)
Alig, Christian, Drees, Manuel, Oda, Kin-ya
In models with ``large'' and/or warped extra dimensions, the higher-dimensional Planck scale may be as low as a TeV. In that case black holes with masses of a few TeV are expected to be produced...
Rotating Black Holes at Future Colliders. III. Determination of Black Hole Evolution (2006)
Ida, Daisuke, Oda, Kin-ya, Park, Seong Chan
TeV scale gravity scenario predicts that the black hole production dominates over all other interactions above the scale and that the Large Hadron Collider will be a black hole factory. Such higher...
Rotating black holes at future colliders II: Anisotropic scalar field emission (2005)
Ida, Daisuke, Oda, Kin-ya, Park, Seong Chan
This is the sequel to the first paper of the series, where we have discussed the Hawking radiation from five-dimensional rotating black holes for spin 0, 1/2 and 1 brane fields in the low frequency...
Anisotropic scalar field emission from TeV scale black hole (2005)
Ida, Daisuke, Oda, Kin-ya, Park, Seong Chan
Black holes are predicted to be copiously produced at the CERN Large Hadron Collider in the scenarios of TeV scale gravity. We report recent progress in studying decay of such a higher dimensional...
Wilson Lines in Warped Space: Dynamical Symmetry Breaking and Restoration (2004)
The dynamics of Wilson lines integrated along a warped extra dimension has been unknown. We study a five dimensional SU(N) pure gauge theory with Randall-Sundrum warped compactification on S^1/Z_2....
Rotating Black Holes at Future Colliders (2003)
Ida, Daisuke, Oda, Kin-ya, Park, Seong Chan
We consider the production and decay of TeV-scale black holes. Evaluation of the production cross section of higher dimensional rotating black holes is made. The master field equation for general...
Rotating Black Holes/Rings at Future Colliders (2003)
Ida, Daisuke, Oda, Kin-ya, Park, Seong Chan
The hierarchy between the electroweak and Planck scales can be reduced when the extra dimensions are compactified with large volume or with warped geometry, resulting in the fundamental scale of the...
Black Holes at future colliders (2003)
Ida, Daisuke, Oda, Kin-ya, Park, Seong Chan
We consider the production and decay of TeV sized black holes. After discussing evaluation of the production cross section of higher dimensional rotating black holes and black rings, the master...

Ida, Daisuke, Oda, Kin-ya, Park, Seong Chan
We study theoretical aspects of the rotating black hole production and evaporation in the extra dimension scenarios with TeV scale gravity, within the mass range in which the higher dimensional Kerr...
Alternative Signature of TeV Strings (2001)
In string theory, it is well known that any hard scattering amplitude inevitably suffers exponential suppression. We demonstrate that, if the string scale is M_s < 2TeV, this intrinsically stringy...
Kitano, Ryuichiro, Oda, Kin-ya
We propose an extension of the supersymmetric standard model with right-handed neutrinos and a singlet Higgs field, and study the neutrino masses in this model. The Majorana masses for the...

Oda, Kin-ya, Takasugi, Eiichi, Tanaka, Minoru, Yoshimura, Masaki
We discussed neutrino masses and mixings in SUSY SO(10) model where quarks and leptons have Yukawa couplings to at least two 10 and one $\bar{126}$ Higgs scalars. In this model, the Dirac and the...
