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. ...
Measurement of R(D) and R(D∗) with a Semileptonic Tagging Method
(American Physical Society, 2020-04-24)
The experimental results on the ratios of branching fractions R(D) = B((B) over bar -> D tau(-)(nu) over bar (tau))/B((B) over bar -> Dl(-)(nu) over bar (e)) and R(D*) = B((B) over bar -> D*tau(-)(nu) over bar (tau))/B((B) ...
On the universality of MOG weak field approximation at galaxy cluster scale
(Elsevier, 2017-07-10)
In its weak field limit, Scalar-tensor-vector gravity theory introduces a Yukawa-correction to the gravitational potential. Such a correction depends on the two parameters, alpha which accounts for the modification of the ...
f (R) Gravity Modifications: From The Action To The Data
(Springer, 2018-03-13)
It is a very well established matter nowadays that many modified gravity models can offer a sound alternative to General Relativity for the description of the accelerated expansion of the universe. But it is also equally ...
Cosmological constrains on fast transition Unified Dark Matter models
(IOP Publishing, 2015)
In this work we show the results obtained applying a Unified Dark Matter (UDM) model with a fast transition to a set of cosmological data. Two different functions to model the transition are tested, and the feasibility of ...
Observational constraints on the unified dark matter and dark energy model based on the quark bag model
(Elsevier, 2014-06-02)
In this work we investigate if a small fraction of quarks and gluons, which escaped hadronization and survived as a uniformly spread perfect fluid, can play the role of both dark matter and dark energy. This fluid, as ...
