Consistent Skyrme parametrizations constrained by GW170817
The high-density behavior of the stellar matter composed of nucleons and
leptons under ~equilibrium and charge neutrality conditions is studied
with the Skyrme parametrizations shown to be consistent (CSkP) with the nuclear
matter, pure neutron matter, symmetry energy and its derivatives in a set of
constraints [Dutra {\it et al.}, Phys. Rev. C 85, 035201 (2012)]. The
predictions of these parametrizations on the tidal deformabilities related to
the GW170817 event are also examined. The CSkP that produce massive neutron
stars give a range of 11.86~\mbox{km} \leqslant R_{1.4} \leqslant
12.55~\mbox{km} for the canonical star radius, in agreement with other
theoretical predictions. It is shown that the CSkP are compatible with the
region of masses and radii obtained from the analysis of recent data from LIGO
and Virgo Collaboration (LVC). A correlation between dimensionless tidal
deformability and radius of the canonical star is found, namely, , with results for the CSkP compatible
with the recent range of from LVC. An
analysis of the graph shows that all the CSkP are
compatible with the recent bounds obtained by LVC. Finally, the universal
correlation between the moment of inertia and the deformability of a neutron
star, named as the \mbox{-Love} relation, is verified for the CSkP, that are
also shown to be consistent with the prediction for the moment of inertia of
the \mbox{PSR J0737-3039} primary component pulsar.Comment: 10 pages, 7 figure
Studies on uracils : synthesis of novel pyrido[2,3-d]- pyrimidine oxides via ring transformation of isoxazolo[3,4-d]pyrimidine
The reaction of isoxazolo[3,4-d]pyrimidine 1 and cyanoolefins 2 in the presence of triethylamine (Et3N) as a catalyst
afforded an unprecedented one-pot synthesis of biologically important pyrido[2,3-d]pyrimidine oxides 3 in excellent yields

Measurements of time-dependent CP asymmetries in decays using a partial reconstruction technique
We report results on time-dependent CP asymmetries in decays based on a data sample containing 657 {\times}
pairs collected with the Belle detector at the KEKB
asymmetric-energy collider at the resonance. We use a
partial reconstruction technique, wherein signal
events are identified using information only from the fast pion from the B
decay and the slow pion from the subsequent decay of the , where the
former (latter) corresponds to final states. We obtain CP
violation parameters and .Comment: 8 pages, 5 figures, 2 tables, submitted to Physical Review D (RC
First test of lepton flavor universality in the charmed baryon decays ωc0 → ω-ℓ+νℓ using data of the Belle experiment
We present the first observation of the ωc0→ω-μ+νμ decay and present measurements of the branching fraction ratios of the ωc0→ω-ℓ+νℓ decays compared to the reference mode ωc0→ω-π+, (ℓ=e or μ). This analysis is based on 89.5 fb-1, 711 fb-1, and 121.1 fb-1 data samples collected with the Belle detector at the KEKB asymmetric-energy e+e- collider at the center-of-mass energies of 10.52 GeV, 10.58 GeV, and 10.86 GeV, respectively. The ωc0 signal yields are extracted by fitting Mωℓ and Mωπ spectra. The branching fraction ratios B(ωc0→ω-e+νe)/B(ωc0→ω-π+) and B(ωc0→ω-μ+νμ)/B(ωc0→ω-π+) are measured to be 1.98±0.13(stat)±0.08(syst) and 1.94±0.18(stat)±0.10(syst), respectively. The ratio of B(ωc0→ω-e+νe)/B(ωc0→ω-μ+νμ) is measured to be 1.02±0.10(stat)±0.02(syst), which is consistent with the expectation of lepton flavor universality
