Real and Virtual Propagation in Neutrino Oscillations
Kenji Nishiwaki, Kin-ya Oda, Juntaro Wada
We revisit flavor oscillations in vacuum in terms of the propagation time of intermediate states. In the limit of a long propagation time (or distance), degenerate intermediate sta…
Implementing Errors on Errors: Bayesian vs Frequentist
Satoshi Mishima, Kin-ya Oda
When combining apparently inconsistent experimental results, one often implements errors on errors. The Particle Data Group's phenomenological prescription offers a practical solut…
Seeing through the light cone: Visualizing electromagnetic fields in special relativity
Daiju Nakayama, Kin-ya Oda, Koichiro Yasuda
The theoretical framework of electromagnetism played a foundational role in Einstein's development of special relativity. To support conceptual understanding, we present a fully sp…
Covariant Electromagnetism in Past-Light-Cone Formalism
Daiju Nakayama, Kin-ya Oda, Koichiro Yasuda
We present a manifestly covariant formulation of relativistic electromagnetism, focusing on the computation of electromagnetic fields from moving charges in a manifestly Lorentz-co…
Irreversible vierbein postulate: Emergence of spacetime from quantum phase transition
Yadikaer Maitiniyazi, Shinya Matsuzaki, Kin-ya Oda +1
We formulate a model for quantum gravity based on the local Lorentz symmetry and general coordinate invariance. A key idea is the irreversible vierbein postulate that a tree-level…
Observational tests for a class of scalar-tensor gravity
Kunio Kaneta, Kin-ya Oda, Motohiko Yoshimura
We study observational bounds in a class of scalar-tensor gravity theories recently proposed. Either an upper or lower bound on a conformal factor in these theories is derived from…
