Abstract We investigate the viability of inflation with a spectator sector comprised non-Abelian gauge fields coupled through higher order operator. dub this model “spectator Gauge-flation”. study predictions for amplitude and tensor tilt chiral gravitational waves conclude that slightly red-tilted power spectrum is preferred . As related models, enhancement r...

We present exploratory analyses of the 3D gluon content proton via a study unpolarized and polarized TMDs at twist-2, calculated in spectator model for parent nucleon. Our approach embodies flexible parametrization spectator-mass function, suited to describe both moderate small-x effects. All these studies can serve as useful guidance investigation dynamics inside nucleons nuclei, which constit...

In this talk I present some of the more recent developments within the Covariant Spectator Theory. My focus will be on aspects of the derivation of gauge invariant electromagnetic threenucleon currents which are consistent with the hadronic equations and with the basic assumptions of this framework. Important dynamical ingredients of the three-nucleon currents are also discussed, namely the thr...

If NMR systems are to be used as practical quantum computers, the number of coupled spins will need to be so large that it is not feasible to rely on purely heteronuclear spin systems. The implementation of a quantum logic gate imposes certain constraints on the motion of those spins not directly involved in that gate, the so-called “spectator” spins; they must be returned to their initial stat...

Though nothing is known for B → ππ,Kπ,KK, we might conjecture that the FSI phases diminish as the initial mass increases. Meanwhile the relative FSI phase is known for the ggg and ”γ” decay amplitudes of the J/ψ decays: 3 ∆δ ≈ 90 and 75 for J/ψ → 00 and 01, respectively. Therefore, if the FSI phases diminish with the increasing initial mass, it should start diminishing somewhere between mJ/ψ an...

We report on the synthesis of a variety of C,E-bidentate triazolylidene ruthenium complexes that comprise different donor substituents E (E = C: phenyl anion; E = O: carboxylate, alkoxide; E = N: pyridine at heterocyclic carbon or nitrogen). Introduction of these donor functionalities is greatly facilitated by the synthetic versatility of triazoles, and their facile preparation routes. Five dif...
