Measurements of the branching fractions B(B- -> (Lambda)over-bar(c)(-)Xi'(0)(c)), B(B- -> (Lambda)over-bar(c)(-)Xi(c )(2645)(0)) and B(B- -> (Lambda)over-bar(c)(-)Xi(c)(2790)(0))
(American Chemical Society, 2019-12-30)
Using the data sample of 711 fb(-1) of Upsilon(4S) on-resonance data taken by the Belle detector at the KEKB asymmetric-energy electron-positron collider, we present the first measurements of branching fractions of the ...
Transverse momentum dependent production cross sections of charged pions, kaons and protons produced in inclusive e(+)e(-) annihilation at root s=10.58 GeV
(American Physical Society, 2019-06-14)
We report measurements of the production cross sections of charged pions, kaons, and protons as a function of fractional energy, the event-shape variable called thrust, and the transverse momentum with respect to the thrust ...
An Exact Approach to Elimination of Leakage in a Qubit Embedded in a Three-level System
(Nature, 2019-07-30)
Leakage errors damage a qubit by coupling it to other levels. Over the years, several theoretical approaches to dealing with such errors have been developed based on perturbation arguments. Here we propose a different ...
Azimuthal asymmetries of back-to-back π±−(π0, η, π±) pairs in e+e− annihilation
(American Physical Society, 2019-11-27)
This work reports the first observation of azimuthal asymmetries around the thrust axis in e(+)e(-) annihilation of pairs of back-to-back charged pions in one hemisphere, and pi(0) and eta mesons in the opposite hemisphere. ...
Non-Abelian anomalies and hadronic fluids
(IOP, 2019)
By using differential geometry methods, we study the role of non-Abelian anomalies in relativistic fluids. We obtain closed expressions for the covariant currents derived from the Chern-Simons effective action. Our results ...
Observation of a vector charmoniumlike state in e(+)e(-) -> D-s(+) D-s1 (2536)(-) + c.c.
(American Physical Society, 2019-12-31)
Using a data sample of 921.9 fb(-1) collected with the Belle detector, we study the process of e(+)e(-)-> Ds+Ds1(2536)(-) + c.c. via initial-state radiation. We report the first observation of a vector charmoniumlike state ...
Measurements of Branching Fraction and Direct CP Asymmetry in B-+/- -> (KSKSK +/-)-K-0-K-0 and a Search for B-+/- -> (KSKS0)-K-0 pi(+/-)
(American Physical Society, 2019-02-20)
We study charmless hadronic decays of charged B mesons to the final states (KSKSK +/-)-K-0-K-0 and (KSKS0)-K-0 pi(+/-) using a 711 fb(-1) data sample that contains 772 x 10(6) B (B) over bar pairs and was collected at the ...
Racetrack potentials and the de Sitter swampland conjectures
(Springer, 2019-01)
We show that one can find de Sitter critical points (saddle points) in models of flux compactification of Type IIB String Theory without any uplifting terms and in the presence of several moduli. We demonstrate this by ...
Observation of Xi(1620)(0) and Evidence for Xi(1690)(0) in Xi(+)(c) -> Xi(-) pi(+) pi(+) Decays
(American Physical Society, 2019-02-21)
We report the first observation of the double strange baryon Xi(1620)(0) in its decay to Xi(-) pi(+) via Xi(+)(c) -> Xi(-)pi(+)pi(+) decays based on a 980 fb(-1) data sample collected with the Belle detector at the KEKB ...
A continued fraction based approach for the Two-photon Quantum Rabi Model
(Nature Publishing, 2019-03-11)
We study the Two Photon Quantum Rabi Model by way of its spectral functions and survival probabilities. This approach allows numerical precision with large truncation numbers, and thus exploration of the spectral collapse. ...
