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 ...
Observation of TransverseΛ= ̄ΛHyperon Polarization ine+e−Annihilation at Belle
(American Physical Society, 2019-01-29)
We report the first observation of the spontaneous polarization of Lambda and (Lambda) over bar hyperons transverse to the production plane in e(+)e(-) annihilation, which is attributed to the effect arising from a polarizing ...
Measurements of Isospin Asymmetry and Difference of Direct CP Asymmetries in Inclusive B→Xsγ Decays
(American Physical Society, 2019-02-20)
We report measurements of isospin asymmetry Delta(0-) and difference of direct CP asymmetries Delta A(CP) between charged and neutral B -> X-s gamma decays. This analysis is based on the data sample containing 772 x 10(6)B ...
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 ...
First Measurements of Absolute Branching Fractions of the Xi(0)(c) Baryon at Belle
(American Physical Society, 2019-02-25)
We present the first measurements of absolute branching fractions of Xi(0)(c) decays into Xi(-)pi(+), Lambda K-pi(+), and pK(-)K(-)pi(+) final states. The measurements are made using a dataset comprising (772 +/- 11) x ...
Search forΩ(2012)→KΞ(1530)→KπΞat Belle
(American Physical Society, 2019-08)
Using data samples of e(+)e(-) collisions collected at the Upsilon(1S), Upsilon(2S), and Upsilon(3S) resonances with the Belle detector, we search for the three-body decay of the Omega(2012) baryon to K pi Xi. This decay ...
Measurement of the CKM matrix element vertical bar V-cb vertical bar from B-0 -> D*(-)l(+)nu(l) at Belle
(American Physical Society, 2019-09-11)
We present a new measurement of the Cabibbo-Kobayashi-Maskawa matrix element vertical bar V-cb vertical bar from B-0 -> D*(-)l(+)nu(l) decays, reconstructed with the full Belle data set of 711 fb(-1) integrated luminosity. ...
Observation of tau(-) -> pi(-)nu(tau)e(+)e(-) and search for tau(-) -> pi(-)nu(tau)mu(+)mu(-)
(American Physical Society, 2019-10-15)
We present the first measurements of branching fractions of rare tau-lepton decays, tau(-) -> pi(-)nu(tau)l(+)l(-) (l = e or mu), using a data sample corresponding to 562 fb(-1) collected at a center-of-mass energy of 10.58 ...
Noncollinearity in dijet fragmentation in electron-positron scattering
(American Physical Society, 2019-08-09)
We study fragmentation in electron-positron annihilation assuming a dijet situation, using variables defined independent of any frame. In a collinear situation some of the variables are centered around zero with the small ...
