Coexistence of Superconductivity and Spin-Splitting Fields in Superconductor/Ferromagnetic Insulator Bilayers of Arbitrary Thickness
(American Physical Society, 2021-05-19)Ferromagnetic insulators (FI) can induce a strong exchange field in an adjacent superconductor (S) via the magnetic proximity effect. This manifests as spin splitting of the BCS density of states of the superconductor, an ... -
Combined analysis of Belle and Belle II data to determine the CKM angle phi(3) using B+ -> D(K(S)(0)h(+)h(-))h(+) decays
(Springer, 2022)[EN] We present a measurement of the Cabibbo-Kobayashi-Maskawa unitarity triangle angle phi(3) (also known as gamma) using a model-independent Dalitz plot analysis of B+ -> D(K(S)(0)h(+)h(-))h(+), where D is either a D-0 ... -

Loop decay in Abelian-Higgs string networks
(APS. American Physical Society, 2021-08-16)We study the decay of cosmic string loops in the Abelian-Higgs model. We confirm earlier results that loops formed by intersections of infinite strings formed from random-field initial conditions disappear quickly, with ... -
Measurement of B(Bs→DsX) with Bs semileptonic tagging
(American Physical Society, 2022)[EN] We report the first direct measurement of the inclusive branching fraction B(B-s -> DsX) via B-s tagging in e(+)e(-) -> gamma(5S) events. Tagging is accomplished through a partial reconstruction of semileptonic decays ... -
