Tangle sums and factorization of A-polynomials
Masaharu Ishikawa, Thomas W. Mattman, Koya Shimokawa
We show that there exist infinitely many examples of pairs of knots, K_1 and K_2, that have no epimorphism preserving peripheral s…
Affine cones over Fano threefolds and additive group actions
Takashi Kishimoto, Yuri Prokhorov, Mikhail Zaidenberg
We address the following question: When an affine cone over a smooth Fano threefold admits an effective action of the additive group? In this paper we deal with Fano threefolds of…
Test of the Conserved Vector Current Hypothesis by beta-ray Angular Distribution Measurement in the Mass-8 System
T. Sumikama, K. Matsuta, T. Nagatomo +9
The beta-ray angular correlations for the spin alignments of 8Li and 8B have been observed in order to test the conserved vector current (CVC) hypothesis. The alignment correlation…
Correlation between flavour violating decay of long-lived slepton and tau in the coannihilation scenario with Seesaw mechanism
Satoru Kaneko, Hiroki Saito, Joe Sato +3
We investigate flavour violating decays of the long-lived lightest slepton and the tau lepton in the coannihilation region of the Minimal Supersymmetric Standard Model with a Seesa…
