o-Benzoquinone dioxime

The title compound, C6H6N2O2, was obtained as a product of an in vitro study of the metabolism of benzofuroxan. The molecule exhibits a amphi configuration of the oxime groups C=N—OH. One oxime group is involved in the formation of a strong intra­molecular O—H⋯N hydrogen bond, while another links mol­ecules into zigzag chains along the c axis via inter­molecular O—H⋯N hydrogen bonds

3-Phenyl­sulfanyl-4-phenyl­sulfonyl-1,2,5-oxadiazole 2-oxide

In the title compound, C14H10N2O4S2,the furoxan heterocyclic ring and the two S atoms are almost co-planar, with a mean deviation of 0.036 Å. The bond lengths in the penta­gonal ring show electron delocalization and the furoxan N—O bond length is quite short [1.211 (3) Å]. The dihedral angles between the central ring and pendant phenyl rings are 78.05 (14) and 84.28 (2)°

4-({4-[Bis(2-cyano­eth­yl)amino]­phen­yl}diazen­yl)benzene­sulfonamide

In the title compound, C18H16N6O2S, which belongs to the family of azo dyes, the dihedral angle between the benzene rings is 26.16 (7)°. In the crystal, mol­ecules are joined by N—H⋯N and C—H⋯N hydrogen bonds into double chains parallel to the a axis

2,3,4,6-Tetra-O-acetyl-2-phthalimido-β-d-glucopyran­oside

In the crystal structure of the title compound, C24H27NO11, a substituted tetra­acetyl glucopyran­oside derivative, weak inter­molecular C—H⋯O hydrogen bonds link the mol­ecules into ribbons propagated in [010]. The d configuration has been attributed on the basis of the synthesis and the β anomer has been determined from the structure

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.
