“…A few additional comments are in order about the size of the QS term. The smallness of this term is because of the large-x behavior of the Sivers function [60,61,91], which can be explored and constrained in future experiments, like those at the 12 GeV upgrade of Jefferson Lab (JLab 12) [92,93]. More specifically, one can only generate a non-negligible QS term if the β parameters (that control the large-x behavior of the Sivers/QS function) are different for up and down quarks [59,91], whereas in Ref.…”

Phenomenological constraints on A in p↑p→πX from Lorentz invariance relations

We present a new analysis of A N in p ↑ p → π X within the collinear twist-3 factorization formalism. We incorporate recently derived Lorentz invariance relations into our calculation and focus on input from the kinematical twist-3 functions, which are weighted integrals of transverse momentum dependent (TMD) functions. In particular, we use the latest extractions of the Sivers and Collins functions with TMD evolution to compute certain terms in A N . Consequently, we are able to constrain the remaining contributions from the lesser known dynamical twist-3 correlators. (Daniel Pitonyak), prokudin@jlab.org (Alexei Prokudin) 1 One could also have C transversely polarized instead of A.2 Studies of the contribution to A N from the convolution of the transversity and Collins TMD functions in the framework of the so-called Generalized Parton Model are presented in Ref. [58]. 3 The dynamical FFs are complex, and we indicate their real and imaginary parts by and superscripts, respectively. 4 Of course there are still uncertainties in these TMD inputs because they are not well-constrained in the forward x F region where A N is large. 5 Note from our discussion before that we can never write the entire cross section only in terms of kinematical functions.

“…3 (right), for varied strength of CME signal which in turn is quadratically dependent on initial axial charge density n 5 /s. Projections based on present analysis of AuAu collisions [12] would hint at a range (n 5 /s) ∼ (5 − 10)%, and a reading from our plot would indicate a measurable absolute difference not only in γ-correlator but also in δ-correlator which are both sensitive to the presence of CME contributions. The number of collected isobar events [12] are about 100 times more than that from our AVFD simulations, thus the experimental analysis would have a statistic error bar about 10 times smaller than that shown in this plot.…”

“…Furthermore it is important to develop new experimental approaches that can help decipher signal from backgrounds [12,13,14,15,16,17,18]. In particular the R-correlator method, proposed by Magdy, Lacey, et al [13,14], shows the promising property of significantly suppressing the backgrounds in the observable.…”

Chiral Magnetic Effect in Isobaric Collisions from Anomalous-Viscous Fluid Dynamics (AVFD)

et al. 2019

The isobaric collision experiment at RHIC provides the unique opportunity to detect the possible signal of Chiral Magnetic Effect (CME) in heavy ion collisions. The idea is to contrast the correlation observables of the two colliding systems that supposedly have identical flow-driven background contributions while quite different CME signal contributions due to the 10% variation in their nuclear charge and thus magnetic field strength. With the recently developed quantitative simulation tool for computing CME signal, the Anomalous-Viscous Fluid Dynamics (AVFD), we demonstrate that a joint (multiplicity + elliptic-flow) event selection is crucial for this purpose. We further propose to use the absolute difference between RuRu and ZrZr events (after using identical event selection) for detecting CME signal and make predictions for the correlation observables.

“…As an example, the Chinese company Jiangsu Kaimao Chemical Technology Co., Ltd, one of the world-wide leading suppliers of formaldehyde plants, filed several patents on the production of anhydrous formaldehyde gas by acetalization with different alcohols such as isobutanol, 4-methylpentan-2-ol or cyclohexanol, followed by phase separation and acetal splitting [27,28]. The same company claims OME production from thus produced formaldehyde and DMM with improvements, e.g., in terms of deacidification and the separation of methyl formate [29,30]. In another process variant, OME 2 is used as a solvent for dry formaldehyde and OME 3 -5 mixtures are produced by reactions of such solutions with DMM [31].…”

To counteract greenhouse gas and other harmful emissions, ambitious regulatory measures with respect to energy generation, supply and consumption have been set. In the fuel sector, successive substitution of common fossil fuels by non‐fossil ones is a promising option to meet the respective demands. Regarding diesel fuels, the use of oxymethylene ethers (OMEs) has been proposed. Especially OMEs of the type CH3O(CH2O)nCH3 (n = 3 – 5) exhibit properties that are similar to common diesel fuel and formation of soot and NOx is drastically reduced during combustion. Within this work, recent progress regarding production, application and evaluation of OMEs is summarized and discussed.
