Euclidean path integrals can be used to prepare states of a Lorentzian QFT. So long as any sources are turned off on the $\textit{t}$ = 0 surface, the resulting Lorentzian states all belong to the same Hilbert space. Constructing more states than allowed by the Lorentzian density of states means that the resulting states must be linearly dependent. For large amplitude sources and a fixed cutoff on energy, the AdS bulk dual of this effect has been conjectured to be captured by spacetime wormholes. Wormholes should then be generic in the presence of large such Euclidean sources; i.e., at large source amplitude one should find wormholes unless the source is fine-tuned in some way.

Are $\textit{S}$ 1 × $\textit{S}$ 2 wormholes generic with large sources?

In the present work, we studied the $$T_{\bar{c}\bar{s}1}^f(2750)$$ state production through the meson loop mechanism in the $$B^+$$ meson decays, where $$T_{\bar{c}\bar{s}1}^f(2750)$$ is considered as a $$\bar{D}K^*$$ molecular state with $$J^P=1^+$$ . By employing the effective Lagrangian approach, we estimated the branching ratio of the $$B^+ \rightarrow D^+ T_{\bar{c}\bar{s}1}^{f}(2750)$$ and $$B^+ \rightarrow D^{*+} T_{\bar{c}\bar{s}1}^f(2750)$$ processes and found them to be on the order of $$10^{-5}\sim 10^{-4}$$ . The fit fraction of $$T_{\bar{c}\bar{s}1}^f(2750)$$ in different processes was also estimated. We propose to search for $$T_{\bar{c}\bar{s}1}^f(2750)$$ in the $$B^+ \rightarrow D^{*+}\bar{D}^{*-}K^+$$ process, which should be accessible to the Belle II and LHCb Collaborations.

$$T_{\bar{c}\bar{s}1}^f(2750)$$ production in the $$B^+$$ decays processes

This paper presents a study of the charmless three-body decays $$ {B}_{(s)}^0\to {K}_{\mathrm{S}}^0{h}^{+}h{\prime}^{-} $$ (where $\textit{h}$ $\textit{′}$ = $\textit{π, K}$), using a sample of $\textit{pp}$ collision data collected by the LHCb experiment during Runs 1 and 2 of the LHC, corresponding to an integrated luminosity of 9 fb . The decay $$ {B}_s^0\to {K}_{\mathrm{S}}^0{K}^{+}{K}^{-} $$ is observed for the first time, and the following ratios of branching fractions are measured:

Improved branching-fraction measurements of $$ {B}_{(s)}^0\to {K}_{\mathrm{S}}^0{h}^{+}h{\prime}^{-} $$ decays and first observation of $$ {B}_s^0\to {K}_{\mathrm{S}}^0{K}^{+}{K}^{-} $$

Using the coalescence model with nucleon and Lambda phase-space distributions generated by the hybrid MUSIC framework, we study the elliptic flow ( <italic>v</italic> <inf>2</inf>) and triangular flow ( <italic>v</italic> <inf>3</inf>) of (anti-)protons, (anti-)deuterons, (anti-) 3He, and <math altimg='si18.svg'><mrow><msubsup><mrow /><mstyle mathvariant='normal'><mi>&#923;</mi></mstyle><mn>3</mn></msubsup><mi mathvariant='normal'>H</mi></mrow></math> in Pb+Pb collisions at <math altimg='si5.svg'><mrow><msqrt><msub><mi>s</mi><mrow><mi>N</mi><mi>N</mi></mrow></msub></msqrt><mo linebreak='goodbreak'>=</mo><mn>5.36</mn></mrow></math> TeV. We find that the simple <italic>v</italic> <inf>2</inf> scaling with the number of constituent nucleons <italic>A</italic> breaks down at high transverse momentum <italic>p<inf>T</inf></italic>/ <italic>A</italic>&#8239;&gt;&#8239;1.5 GeV/ <italic>c</italic>, while an improved scaling relation holds well up to <italic>p<inf>T</inf></italic>/ <italic>A</italic>&#8239;&#8776;&#8239;3 GeV/ <italic>c</italic>. In contrast, <italic>v</italic> <inf>3</inf> exhibits similar behavior under both scaling prescriptions, with no significant difference. We also make predictions for <italic>v</italic> <inf>2</inf> and <italic>v</italic> <inf>3</inf> of the hypertriton and find these flows are insensitive to the Lambda-deuteron ( <math altimg='si23.svg'><mrow><mstyle mathvariant='normal'><mi>&#923;</mi></mstyle><mo linebreak='goodbreak'>&#8722;</mo><mi>d</mi></mrow></math>) distance inside the hypertriton. Our results are compared with preliminary experimental measurements by the ALICE Collaboration and offer insight into the production mechanisms of light (anti-)(hyper-)nuclei in high-energy heavy-ion collisions.

We examine the <italic>q</italic> 2-binned distributions of the <italic>D</italic>&#8239;&#8594;&#8239; <italic>K&#956;&#957;</italic> decay rate and of the corresponding forward-backward asymmetry which were recently measured by BESIII, showing a mild deviation from the Standard Model predictions. We point out that the proposed solution to remedy the discrepancy by turning on a complex-valued New Physics coupling is in tension with the constraints deduced from the LHC bounds on the high- <italic>p<inf>T</inf></italic> tail of the relevant Drell-Yan process. We then show that there are several plausible scenarios that are compatible with both the measured low-energy and high-energy constraints but the selected couplings appear to be too small to be observed in the measurements of integrated observables, except for possibly the <italic>q</italic> 2-binned distribution of the angular observables relevant to <italic>D<inf>s</inf></italic>&#8239;&#8594;&#8239; <italic>&#981;</italic>(&#8239;&#8594;&#8239; <italic>KK</italic>) <italic>&#956;&#957;</italic> or &#923; <inf><italic>c</italic></inf>&#8239;&#8594;&#8239;&#923;(&#8239;&#8594;&#8239; <italic>p&#960;</italic>) <italic>&#956;&#957;</italic> modes.
