The compact tetraquark states with fully heavy quark contents $QQ\overline{Q}\overline{Q}$ are studied as the bound of diquark-antidiquark within Bethe-Salpeter framework. (anti)diquark masses and form factors used same we calculated doubly baryons in a previous work. Under instantaneous approximation, three-dimensional (Bethe-)Salpeter equation tetraquarks is derived solved numerically to obtain corresponding mass spectra wave functions ${J}^{PC}={0}^{++}$, ${1}^{+\ensuremath{-}}$,...
Background The model cellulolytic fungus Trichoderma reesei (teleomorph Hypocrea jecorina) is capable of responding to environmental cues compete for nutrients in its natural saprophytic habitat despite genome encodes fewer degradative enzymes. Efficient signalling pathways perception and interpretation signals are indispensable this process. Ras GTPases represent a kind critical signal proteins involved transduction regulation gene expression. In T. the contains two subfamily small TrRas1...
The asymmetric allylation of 1-pyrroline-5-carboxylic esters has been accomplished through a synergistic Pd/Cu catalyst system under mild reaction conditions. mechanistic studies suggested that (1) nucleophilic attack is the enantiodiscriminating step; (2) cooperative action two chiral reactive species, N-metalated azomethine ylides and π-allylpalladium, most likely responsible for its high reactivity excellent enantioselectivity (up to >99% ee); (3) steric hindrance electronic factors...
An important process in the generation of tolerance to peripheral self-Ags is induction unresponsiveness mature specific T cells. Although end stage this process, termed anergy, well defined, pathway by which naive cells become anergic remains be elucidated. Using an vivo self-tolerance model, we demonstrate that CD4(+) pass through a significant effector on their way state. This characterized production cytokines, provision help for CD8(+) cells, and pathology within organs express cognate...
Radiative E1 decay widths of $\rm X(3872)$ are calculated through the relativistic Salpeter method, with assumption that is $\chi_{c1}$(2P) state, which radial excited state $\chi_{c1}$(1P). We firstly width $\chi_{c1}$(1P), result in agreement experimental data excellently, then we case assignment it $\chi_{c1}$(2P). Results are: ${\Gamma}({\rm X(3872)}\rightarrow \gamma \sl J/\psi)=33.0$ keV, \psi(2S))=146$ keV and \psi(3770))=7.09$ keV. The ratio ${{\rm...

Abstract 3,3‐Disubstituted oxindoles bearing quaternary and tertiary stereogenic centers are privileged structural motifs, which widely exist in pharmaceutical natural products. Herein, a highly regio‐, enantio‐, diastereoselective allylic alkylation of 3‐alkyl through synergistic iridium copper catalysis is described, provides series 3,3‐disubstituted oxindole derivatives containing adjacent excellent yields, enantiomeric excess, diastereomeric ratio (for 30 examples, up to 97 % yield,...
Relativistic effects are important in the rigorous study of heavy quarks. In this paper, we relativistic corrections semileptonic ${B}_{c}$ decays to charmonium with instantaneous Bethe-Salpeter method. Within framework, use two methods effects. One them is expand transition amplitude powers $\stackrel{\ensuremath{\rightarrow}}{q}$ which relative momentum between quark and antiquark, other base on wave functions. level decay width, results show that, for...

ABSTRACT Emerging tick-borne orthonairovirus infections pose a growing global concern, with limited understanding of the viral ovarian tumor-like cysteine proteases (vOTUs) encoded by novel orthonairoviruses. These vOTUs, group deubiquinylases (DUBs), disrupt innate immune response. Yezo virus (YEZV), recently discovered pathogenic orthonairovirus, was first reported in Japan 2021. In this study, we successfully isolated and identified YEZV new Jiànchuān tick (JCTV), from Ixodes persulcatus...
We study the productions of first radial excited states $D_q(2S)$ ($q=u, d, s$) and $B_q(2S)$ in exclusive semi-leptonic $B_{q'}$ ($q'=u, d s, c$) decays by improved Bethe-Salpeter method. These 2S can be detected through their strong to ground mesons, where are calculated low energy approximation as well impulse approximation. Some channels have ratios order $10^{-4}$: $Br(B^+\to\bar D^0(2S)\ell^+{\nu_\ell})\times Br(\bar D^0(2S)\to \bar D^{*}\pi)\approx(4.9\pm4.0)\times10^{-4}$, $Br(B^0\to...
The recent BaBar results raise the possibility that X(3872) has negative parity; reassigning it to state should therefore be considered. In this paper we give a general form of wave function 2−+ mesons. By solving instantaneous Bethe–Salpeter equation, get mass spectrum and corresponding functions. We calculate electromagnetic decay widths first which assume particle. are Γ(2−+(3872) → J/ψγ) = 1.59+0.53−0.42 keV, ψ(2S)γ) 2.87+1.46−0.97 eV ψ(3770)γ) 0.135+0.066−0.047 keV. ratio branch...
We study the semi-leptonic and non-leptonic decays of $B_c$ meson to $D$-wave charmonia, namely, $\eta_{c2}(1^1\!D_2)$, $\psi_2(1^3\!D_2)$, $\psi_3(1^3\!D_3)$. In our calculations, instantaneous Bethe-Salpeter method is applied achieve hadronic matrix elements. This includes relativistic corrections which are important especially for higher orbital excited states. For decay channels with electron as final lepton, we get branching ratios $\mathcal{B}[B_c \rightarrow \eta_{c2}e\bar{\nu}_e] =...
Based on the effective Lagrangian in heavy quark limit, we calculate one-boson-exchange interaction kernel of $P_\psi^N(4312)^+$ as $\bar D\Sigma_c$ molecular state isospin-$\frac12$. We present Bethe-Salpeter equation and wave function for constituent particles to be a (pseudo)scalar meson $\frac12$ baryon. By solving equation, obtain with $J^P=(\frac{1}{2})^-$. Combining obtained BS function, partial decay widths $J/\psi p$, $\eta_c D^{*0}\Lambda_c^+$ D^0\Lambda_c^+$ are calculated $0.17$,...
In this paper, we study the OZI-allowed two-body strong decays of $$3^-$$ heavy–light mesons. Experimentally charmed $$D_{3}^{*}(2760)$$ and charm–strange $$D_{s3}^{*}(2860)$$ states with these quantum numbers have been discovered. For bottomed B(5970) state, which was found by CDF Collaboration recently, its number has not decided yet assume it is a meson in paper. The theoretical prediction for bottom–strange state $$B_{s3}^*$$ also given. relativistic wave functions heavy mesons are...
The existence of heavy meson lepton number violating (LNV) processes shows the Majorana nature neutrino. Much this theoretical and experimental researche focuses on type decay. Four-body epton-number violation B may have sizable branching ratios as they share same vertex mixing parameters with three-body case. Mixing between neutrino charged leptons extracted from case can be used to constrain four-body decays meson. So we update upper limits these new data LNV decays. We also analyze using...
