[en] In this study, we investigate muon , , and anomalies in a specific model with one doublet, one triplet, and one singlet scalar leptoquark (LQ). When the strict limits from the , , , and processes are considered, it is difficult to use one scalar LQ to explain all of the anomalies due to the strong correlations among the constraints and observables. After ignoring the constraints and small couplings, the muon can be explained by the doublet LQ alone due to the enhancement, whereas the measured and unexpected smaller requires the combined effects of the doublet and triplet LQs, and the and excesses depend on the singlet LQ through scalar- and tensor-type interactions.
[en] Highlights: • The mechanisms of the CH3O2 + H reaction was studied theoretically. • The reaction can take place on the singlet and triplet potential energy surfaces. • The total rate constants show pressure independence. Singlet and triplet potential energy surfaces for the CH3O2 with H reaction have been investigated computationally to propose the reaction mechanisms and possible products. On the singlet PES, addition-dissociation was located. At 3.65 Torr with He as bath gas, the formation of CH2O + H2O channel is dominated at the whole temperature range. Furthermore, the predicted rate constants for at 298 K 3.65 Torr of He agree well with the available experimental values. The pathways on the triplet PES will not compete with the pathways on the singlet PES in kinetically.
[en] In this paper we determine the fusion rules of the logarithmic Wp,q triplet theory and construct the Grothendieck group with subgroups for which consistent product structures can be defined. The fusion rules are then used to determine projective covers. This allows us also to write down a candidate for a modular invariant partition function. Our results demonstrate that recent work on the W2,3 model generalizes naturally to arbitrary (p, q).
[en] The search for new forms of spin-triplet pairing is an important goal in superconductivity. The purpose of this contribution is to point out a surprising connection between the Edelstein effect in noncentrosymmetric superconductors and the nonunitary (spin-polarized) pairing in triplet superfluids with a complex d vector. It will be shown that the Edelstein effect leads to a new form of the nonunitary spin-triplet pairing which is generated electrically by a supercurrent in an initially TR-invariant (unpolarized) system. Such a nonunitary state can be induced in a wide class of noncentrosymmetric superconductors, including those with a real d vector and proximity structures with d=0. I will also discuss how to detect the nonunitary spin-triplet pairing by Andreev reflection. These results indicate an unexplored route for electrical manipulation of spin-triplet superconductivity in noncentrosymmetric materials.
[en] Multiple Zhang-Rice type spectral features have been observed in resonant inelastic X-ray scattering (RIXS) from the quasi-one-dimensional cuprate charge transfer insulator Li2CuO2. The first feature appears at constant emission energy, and is associated with a Zhang-Rice singlet final state. The second is an interplaquette charge transfer excitation that results in a novel triplet Zhang-Rice-type final state. It is accompanied by the presence of a O 2p nonbonding to upper Hubbard band excitation at an energy close to that of a calculated triplet charge transfer Zhang-Rice-type excitation. The site selectivity and polarization rules associated with RIXS allows these two excitations to be distinguished
[en] We report here the photophysical properties of a naphthalene derivative of a specially designed cryptand system (L). The system exhibits the unusual phenomenon of emission from T2 and T1 states of naphthalene which has been attributed to the inherent rigidity of the system. The results obtained have been analysed by comparison with two other model systems where the flexibility of the fluorophore unit with respect to the receptor moiety have been varied
[en] The Einstein–Podolsky–Rosen paradox is considered using spin- 1/2 singlet and triplet states prepared in the z-direction, after which measurements are made in a different direction, the x-direction, for example. An unexpected outcome and its usefulness for teaching is reported. The material will be of interest to upper-year undergraduate quantum mechanics instructors and students. (paper)
[en] We consider a comprehensive set of simplified models that contribute to final states with top and bottom quarks at the LHC. These simplified models are used to create minimal search strategies that ensure optimal coverage of new heavy flavor physics involving the pair production of color octets and triplets. We provide a set of benchmarks that are representative of model space, which can be used by experimentalists to perform their own optimization of search strategies. For data sets larger than 1 fb-1, same-sign dilepton and 3b search regions become very powerful. Expected sensitivities from existing and optimized searches are given.
[en] Mechanical loW--β triplet vibrations lead to horizontal jitter of RHIC beams at frequencies around 10 Hz. The resulting beam offsets at the interaction points are considered detrimental to RHIC luminosity performance. To stabilize beam orbits at the interaction points, installation of a fast orbit feedback is foreseen. A prototype of this system is being developed and tested. Recent results will be presented
