On the Relation Between Mechanisms for Single-Transverse-Spin Asymmetries

Yuji Koike, Werner Vogelsang, Feng Yuan

Recent studies have shown that two widely-used mechanisms for single-transverse-spin asymmetries based on either twist-three contributions or on transverse-momentum-dependent (Sive…

False Vacuum in the Supersymmetric Mass Varying Neutrinos Model

Ryo Takahashi, Morimitsu Tanimoto

We present detailed analyses of the vacuum structure of the scalar potential in a supersymmetric Mass Varying Neutrinos model. The observed dark energy density is identified with f…

T-odd asymmetries in radiative top-quark decays

Kaoru Hagiwara, Kentarou Mawatari, Hiroshi Yokoya

We study the angular distribution of the charged lepton in the top-quark decay into a bottom quark and a W boson which subsequently decays into \ellν_{\ell}, when a hard gluon is r…

Factorization and Gauge Invariance of Twist-3 Cross Section for Single Spin Asymmetry

Yuji Koike, Kazuhiro Tanaka

We prove factorization and gauge invariance of the twist-3 single-spin-dependent cross section in the leading order perturbative QCD, which was missing in the previous literature.…

Novel Master Formula for Twist-3 Soft-Gluon-Pole Mechanism to Single Transverse-Spin Asymmetry

Yuji Koike, Kazuhiro Tanaka

We prove that twist-3 soft-gluon-pole (SGP) cross section for single spin asymmetries is determined by a certain ``primordial'' twist-2 cross section up to kinematic and color fact…

Single Longitudinal-Spin Asymmetries in Lepton-Pair Production at RHIC and J-PARC

Hiroshi Yokoya

We study the single longitudinal-spin asymmetries in lepton-pair production with large transverse-momentum at RHIC and J-PARC experiments. The asymmetries in the azimuthal angular…

Dark energy and neutrino model in SUSY -- Remarks on active and sterile neutrinos mixing --

Ryo Takahashi, Morimitsu Tanimoto

We consider a Mass Varying Neutrinos (MaVaNs) model in supersymmetric theory. The model includes effects of supersymmetry breaking transmitted by the gravitational interaction from…

Quark and lepton mass matrices with family symmetry

H. Sawanaka

Realistic quark masses and mixing angles are obtained applying the successful family symmetry for leptons, motivated by the quark-lepton assignments of SU(5). The symme…

Universal Structure of Twist-3 Soft-Gluon-Pole Cross Sections for Single Transverse-Spin Asymmetry

Yuji Koike, Kazuhiro Tanaka

We prove that twist-3 soft-gluon-pole (SGP) cross section for single spin asymmetries (SSA) is determined by a certain ``primordial'' twist-2 cross section up to kinematic and colo…

Examining the Geometrical Model with Inverted Mass Hierarchy for Neutrinos

Mizue Honda, Morimitsu Tanimoto

The comprehensive analyses are presented in the model with the inverted mass hierarchy for neutrinos, which follows from a geometrical structure of a (1+5) dimensional space-time w…
