Ultra Light Axionic Dark Matter: Galactic Halos and Implications for Observations with Pulsar Timing Arrays
(MDPI, 2018-01-16)
The cold dark matter (CDM) paradigm successfully explains the cosmic structure over an enormous span of redshifts. However, it fails when probing the innermost regions of dark matter halos and the properties of the Milky ...
Measurement of the Tau Michel Parameters (Eta)Over-Bar and Xi Kappa in the Radiative Leptonic Decay Tau(-) -> L(-)Nu(Tau)(Nu)Over-Bar(L)Gamma
(Oxford University Press, 2018-02)
We present a measurement of the Michel parameters of the tau lepton, (eta) over bar and xi kappa, in the radiative leptonic decay tau(-) -> l(-)nu(tau)(nu) over bar (l)gamma using 711 fb(-1) of collision data collected ...
Search for B- -> mu(-)(nu)over-bar(mu) Decays at the Belle Experiment
(Amer Physical SOC, 2018-07-18)
We report the results of a search for the rare, purely leptonic decay B- -> mu(-)(nu) over bar (mu) performed with a 711 fb(-1) data sample that contains 772 x 10(6) B (B) over bar pairs, collected near the Upsilon(4S) ...
Observation of Υ(4S) → η1 Υ (1S)
(American Physical Society, 2018-08-06)
We report the first observation of the hadronic transition Upsilon(4S) -> eta'Upsilon(1S), using 496 fb(-1) data collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. ...
Solitons and black hole in shift symmetric scalar-tensor gravity with cosmological constant
(Springer, 2018-06-14)
We demonstrate the existence of static, spherically symmetric globally regular, i.e. solitonic solutions of a shift-symmetric scalar-tensor gravity model with negative cosmological constant. The norm of the Noether current ...
