Yukawa enhancement of Z-mediated new physics in ∆S = 2 and ∆B = 2 processes [PDF]

open access: yes, 2017
A bstractWe discuss Yukawa-enhanced contributions from Z-mediated new physics to down-type quark ΔF = 2 processes in the framework of the standard model gauge-invariant effective theory (SMEFT).

Physics potentials with the second Hyper-Kamiokande detector in Korea [PDF]

open access: yesProgress of Theoretical and Experimental Physics, 2016
We have conducted sensitivity studies on an alternative configuration of the Hyper-Kamiokande experiment by locating the 2nd Hyper-Kamiokande detector in Korea at $\sim$1100$-\ $1300 km baseline.

Majorana’s approach to nonadiabatic transitions validates the adiabatic-impulse approximation

open access: yesScientific Reports, 2023
The approach by Ettore Majorana for non-adiabatic transitions between two quasi-crossing levels is revisited and significantly extended. We rederive the transition probability, known as the Landau–Zener–Stückelberg–Majorana formula, and introduce ...

Probing New Physics in b → d transitions

open access: yesJournal of High Energy Physics, 2020
Recent experimental data on several observables in semileptonic B-meson decays are found to be in tension with the corresponding Standard Model predictions. Most of these deviations are related to b → c and b → s flavour changing transitions.

Ferromagnetism in two-dimensional hole-doped SnO

open access: yesAIP Advances, 2018
Hole-doped monolayer SnO has been recently predicted to be a ferromagnetic material, for a hole density typically above 5x1013/cm2. The possibility to induce a hole-doped stable ferromagnetic order in this two-dimensional material, either by intrinsic or
