Study of Electromagnetic Decays of Orbitally Excited Xi(C) Baryons
(American Physical Society, 2020-10-26)
Using 980 fb(-1) of data collected with the Belle detector operating at the KEKB asymmetric-energy e(+) e(-) collider, we report a study of the electromagnetic decays of excited charmed baryons Xi(c)(2790) and Xi(c)(2815). ...
Nontopological Solitons in Abelian Gauge Theories Coupled to U(1) x U(1) Symmetric Scalar Fields
(American Physical Society, 2020-10-27)
In a series of recent works, Ishihara and Ogawa have investigated nontopological solitons (Q-balls) in a spontaneously broken Abelian gauge theory coupled to two complex scalar fields. The present paper extends their ...
Bound Entangled Singlet-Like States for Quantum Metrology
(American Physical Society, 2021-05-10)
Bipartite entangled quantum states with a positive partial transpose (PPT), i.e., PPT entangled states, are usually considered very weakly entangled. Since no pure entanglement can be distilled from them, they are also ...
Charge Screening in the Abelian Higgs Model
(Springer, 2021-03-18)
In the Abelian Higgs model electric (and magnetic) fields of external charges (and currents) are screened by the scalar field. In this contribution, complementing recent investigations of Ishihara and Ogawa, we present a ...
ModMax meets Susy
(Springer, 2021-10-05)
[EN]We give a prescription for N = 1 supersymmetrization of any (four-dimensional) nonlinear electrodynamics theory with a Lagrangian density satisfying a convexity condition that we relate to semi-classical unitarity. We ...
Dalitz analysis of D0 → K− π+ η decays at Belle
(American Physical Society, 2020-07-06)
[EN] We present the results of the first Dalitz plot analysis of the decay D0 → K−πþη. The analysis is
performed on a data set corresponding to an integrated luminosity of 953 fb−1 collected by the Belle
detector at the ...
Superstring at the boundary of open supermembrane interacting with D=4 supergravity and matter supermultiplets
(Springer, 2019-12-13)
[EN] We present the complete supersymmetric and κ-symmetric action for the 4-
dimensional interacting system of open supermembrane, dynamical supergravity and 3-
form matter multiplets. The cases of a single 3-form matter ...
Search for B0 decays to invisible final states ( + γ) at Belle
(American Physical Society, 2020-07-08)
We report searches for B0→invisible and B0→invisible+γ decays, where the energy of the photon is required to be larger than 0.5 GeV. These results are obtained from a 711 fb−1 data sample that contains 772×106B¯B pairs ...
Variant 4D supergravities and membranes
(IOP, 2019)
We review the dynamical generation of coupling constants in supergravity by means of gauge three-forms. The latter are introduced as components of particular variant chiral multiplets and can be coupled to membranes ...
Observation of the Radiative Decays of Υ(1S) to χc1
(American Physical Society, 2020-03-26)
We report the first observation of the radiative decay of the Upsilon(1S) into a charmonium state. The significance of the observed signal of Upsilon(1S) -> gamma chi(c1) is 6.3 standard deviations including systematics. ...
