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 ...
PDF profiling using the forward-backward asymmetry in Neutral Current Drell-Yan production
(Springer, 2019-10-15)
Non-perturbative QCD effects from Parton Distribution Functions (PDFs) may be constrained by using high-statistics Large Hadron Collider (LHC) data. Drell-Yan (DY) measurements in the Charged Current (CC) case provide one ...
Evidence for B+ -> h(c)K(+) and observation of eta(c()2S) -> p(p)over-bar pi(+)pi(-)
(American Physical Society, 2019-07-10)
A search for the decays B+ -> h(c)K(+) and B-0 -> h(c)K(S)(0) is performed. Evidence for the decay B+ -> h(c)K(+) is found; its significance is 4.8 sigma. No evidence is found for B-0 -> h(c)K(S)(0). The branching fraction ...
Search for X(3872) and X(3915) decay into chi(c1)pi(0) in B decays at Belle
(American Physical Society, 2019-06-12)
We report a search for X(3872) and X(3915) in B+ ->chi(c1)pi K-0(+) decays. We set an upper limit of B(B+ -> X(3872)K+) x B(X(3872) -> chi(c1)pi(0)) < 8.1 x 10(-6) and B(B+ -> X(3915)K+) x B(X(3915) -> chi(c1)pi(0)) < 3.8 ...
Semi-inclusive deep-inelastic scattering in Wandzura-Wilczek-type approximation
(Springer, 2019-06-04)
We present the complete cross-section for the production of unpolarized hadrons in semi-inclusive deep-inelastic scattering up to power-suppressed O(1/Q(2) terms in the Wandzura-Wilczek-type approximation, which consists ...
First measurement of the CKM angle ϕ3 with B±→ D(K0S π+π−π0) K± decays
(Springer, 2019-10-16)
We present the first model-independent measurement of the CKM unitarity triangle angle phi(3) using B-+/--> D(K-S(0)pi(+)pi(-)pi(0)) K-+/- decays, where D indicates either a D-0 or (D) over bar (0) meson. Measurements of ...
