“…In the present Section, we will present here only the final expressions of the EM transition form factors, since detailed formalisms of how to derive the form factors of the SU(3) baryons can be found in previous works. For a detailed calculation, we refer to a recent work on the EM form factors of the baryon decuplet [46] and a review [47]. Having taking into account the rotational 1/N c and linear m s corrections, we obtain the magnetic dipole form factor G * M 1 as…”

We investigate the electromagnetic transition form factors of the baryon decuplet to the baryon octet, based on the self-consistent SU(3) chiral quark-soliton model, taking into account the effects of explicit breaking of flavor SU(3) symmetry. We emphasize the Q 2 dependence of the electromagnetic N → ∆ transition form factors and the ratios of E2/M 1 and C2/M 1 in comparison with the experimental and empirical data. In order to compare the present results of the electromagnetic transition form factors of the N → ∆ with those from lattice QCD, we evaluate the form factors with the pion mass deviated from its physical value. The results of the E2/M 1 and C2/M 1 ratios are in good agreement with the lattice data. We also present the results of the electromagnetic transition form factors for the decuplet to the octet transitions.Keywords: Electromagnetic transition form factors of the baryon decuplet, E2/M 1 ratios, pion mean fields, the chiral quark-soliton model *

“…This parameter range corresponds to the UV limit and may give rise to a good guide line to figure out physical implication of the numerical study. Ignoring higher order corrections caused by the t 2 term as explained before, the leading contribution to the entanglement entropy for ρ * /R 1 is governed by [50][51][52][53][54]…”

We investigate the time-dependent entanglement entropy in the AdS space with a dS boundary which represents an expanding spacetime. On this time-dependent spacetime, we show that the Ryu–Takayanagi formula, which is usually valid in the static spacetime, provides a leading contribution to the time-dependent entanglement entropy. We also study the leading behavior of the entanglement entropy between the visible and invisible universes in an inflationary cosmology. The result shows that the quantum entanglement monotonically decreases with time and finally saturates a constant value inversely proportional to the square of the Hubble constant. Intriguingly, we find that even in the expanding universes, the time-dependent entanglement entropy still satisfies the area law determined by the physical distance.

We investigate the holographic quantum entanglement of a visible universe in an inflationary cosmology. To do so, we consider an AdS space with a dS boundary which represents an expanding space in time. In an inflationary cosmology, there exists a natural entangling surface called a cosmic event horizon which divides a universe into visible and invisible parts. In this model, cosmic event horizon monotonically decreases and approaches a constant value proportional to the inverse of Hubble constant. We show that the quantum entanglement between the visible and invisible universes divided by cosmic event horizon decreases monotonically in time. After an infinite time evolution, it finally approaches a constant value which is proportional to the inverse square of the Hubble constant for a four-dimensional dS space.
