Based on the expectations that the lowest-lying double-bottom tetraquark$T_{bb\bar u \bar d}$ ($J^P=1^+$) and the bottom-charm tetraquark $T_{bc\bar u \bar d}$ ($J^P=0^+$) are stable against strong and electromagnetic decays, we work outa number of semileptonic and non-leptonic weak decays of these hadrons, making use of the heavy quark symmetry. In doing this, we concentrate on the exclusive decays involving also tetraquarks in the final states, i.e., transitionssuch as $T_{bb\bar u \bar d} \to T_{bc\bar u \bar d} (\ell^- \nu_\ell,h^-)$ and $T_{bc\bar u \bar d} \to T_{cc\bar u \bar d} (\ell^- \nu_\ell,h^-)$, where $h^-=\pi^-,\rho^-,a_1^-$.

The studies of polaronic centers in a homologous series of scheelite-type compounds AWO$_4$ (A =Ca, Sr, Ba) were performed using the W L$_3$-edge and Sr K-edge X-ray absorption spectroscopy combined with the reverse Monte Carlo simulations, X-ray photoelectron spectroscopy (XPS), and first-principles calculations. Protonated scheelites H$_x$AWO$_4$ were produced using acid electrolytes in a one-step route at ambient conditions. [...]

Ubiquitin ligases (E3s) are pivotal specificity determinants in the ubiquitin system by selecting substrates and decorating them with distinct ubiquitin signals. However, structure determination of the underlying, specific E3-substrate complexes has proven challenging owing to their transient nature. [...]

Infectious diseases are a significant cause of death, and recent studies estimate that common bacterial infectious diseases were responsible for 13.6% of all global deaths in 2019. Among the most significant bacterial pathogens is Staphylococcus aureus, accounting for more than 1.1 million deaths worldwide in 2019. [...]

We present the nuclear magnetic resonance spectroscopy (NMR) solution structure of the 5′-terminal stem loop 5_SL1 (SL1) of the SARS-CoV-2 genome. SL1 contains two A-form helical elements and two regions with non-canonical structure, namely an apical pyrimidine-rich loop and an asymmetric internal loop with one and two nucleotides at the 5′- and 3′-terminal part of the sequence, respectively. [...]

A search for a heavy CP-odd Higgs boson, A, decaying into a Z boson and a heavy CP-even Higgs boson, H, is presented. It uses the full LHC Run 2 dataset of pp collisions at $ \sqrt{s} $ = 13 TeV collected with the ATLAS detector, corresponding to an integrated luminosity of 140 fb$^{−1}$ [...]

This paper reports cross-section measurements of $ZZ$ production in $pp$ collisions at $\sqrt{s}=13.6$ TeV at the Large Hadron Collider. The data were collected by the ATLAS detector in 2022, and correspond to an integrated luminosity of 29 fb$^{-1}$. [...]

A combination of searches for resonant Higgs boson pair production is presented, using up to 139 fb$^{-1}$ of $pp$ collision data at $\sqrt{s}=13$ TeV recorded with the ATLAS detector at the LHC. The combination includes searches performed in three decay channels: $b\bar{b}b\bar{b}$, $bb\tau^+\tau^-$ and $bb\gamma\gamma$. [...]

This paper presents the measurement of fiducial and differential cross sections for both the inclusive and electroweak production of a same-sign W-boson pair in association with two jets (W$^{±}$W$^{±}$jj) using 139 fb$^{−1}$ of proton-proton collision data recorded at a centre-of-mass energy of $ \sqrt{s} $ = 13 TeV by the ATLAS detector at the Large Hadron Collider. The analysis is performed by selecting two same-charge leptons, electron or muon, and at least two jets with large invariant mass and a large rapidity difference [...]

A search for the decay of the Higgs boson to a Z boson and a light, pseudoscalar particle, a, decaying respectively to two leptons and to two photons is reported. The search uses the full LHC Run 2 proton–proton collision data at s=13 TeV, corresponding to 139 fb−1 collected by the ATLAS detector. [...]
