We interpret the Euclidean solution of JT de Sitter gravity as the Coleman-de Luccia instanton for the decay of the low-entropy horizon of its static patch solution into either a Big Crunch or an infinite-entropy Lorentzian de Sitter cosmology. As in previous work by one of the authors, the Big Crunch is interpreted as bounding the entropy of the static state. The principle of detailed balance then guarantees it will transition back to a higher entropy causal diamond in the expanding cosmology. We then construct a family of explicit quantum mechanical models and appropriate metastable states, with transition probabilities well approximated by the semi-classical calculations in JT de Sitter gravity.

The flavor-changing neutral current semileptonic decays of <italic>B</italic> mesons provide an excellent platform for indirectly probing New Physics (NP) beyond the Standard Model (SM).

Conformal 3-point correlators of conserved currents play important roles in numerous directions. These correlators are fixed by conformal symmetry up to a few parameters, which are known only at leading order in perturbative expansions. The major challenges come from the multi-loop Feynman integrals with three external momenta. In this work, we employ the method of subgraphs to compute the subleading order corrections to the conformal current 3-point correlators in the large $\textit{N}$ expansion. We show that the method of subgraphs generates diagrammatic expansions for the conformal 3-point correlators, and that it is closely related to the operator product expansions in momentum space. We verify the subgraph expansions of conserved current 3-point correlators using exact results in 3D. We demonstrate that multi-loop 3-point Feynman integrals can be significantly simplified by taking the subgraph expansions. Due to constraints from conformal symmetry, it suffices to keep only the first few terms in the subgraph expansions to completely fix the subleading order corrections. We apply this method to compute the 1/$\textit{N}$ corrections to current correlators 〈$\textit{JJJ}$〉 in the critical $\textit{O}$($\textit{N}$) vector model and the Gross-Neveu-Yukawa model. We also compute the 1/$\textit{N}$ corrections to the coefficients in the current-current-scalar correlators 〈$\textit{JJσ}$ 〉 and 〈$\textit{JJσ}$〉 in the critical $\textit{O}$($\textit{N}$) vector model. We compare the perturbative results with the bootstrap data and discuss their application to conductivity near the quantum critical point.

Duality symmetries have been extensively investigated in various contexts, playing a crucial role in understanding quantum field theory and condensed matter theory. In this paper, we extend this framework by studying $\textit{N}$ -ality symmetries, which are a generalization of duality symmetries and are mathematically described by ℤ -graded fusion categories. In particular, we focus on an $\textit{N}$ -ality symmetry obtained by gauging a non-anomalous subgroup of ℤ × ℤ × ℤ symmetry with a type III anomaly. We determine the corresponding fusion rules via two complementary approaches: a direct calculation and a representation-theoretic method. As an application, we study the symmetry-protected topological (SPT) phases associated with the $\textit{N}$ -ality symmetry. We classify all such SPT phases using the SymTFT framework and explicitly construct lattice Hamiltonians for some of them.

We investigate the leading-power fragmentation of fully charmed pentaquark states ($\textit{S}$-wave $$|c\bar{c}ccc\rangle $$ pentacharms) at hadron colliders. We introduce a new set of multimodal collinear fragmentation functions, named . They rely on an enhanced calculation of the initial-scale input for the constituent heavy-quark fragmentation channel, making them well suited to describe the short-distance emission of either a compact multicharm state or a dicharm-charm-dicharm configuration. To explore phenomenological implications, we use the multimodular interface to study NLL/NLO $$^+$$ semi-inclusive production rates for pentacharm-plus-jet systems at the forthcoming HL-LHC and the future FCC. Our analysis represents a further step toward bridging the domains of hadronic structure, precision QCD, and exotic matter.

A measurement of event-shape variables is presented, using a data sample produced in a special run with approximately one inelastic proton-proton collision per bunch crossing. The data were collected with the CMS detector at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mrow><mn>64</mn><mtext> </mtext><mtext> </mtext><mrow><mi mathvariant="normal">μ</mi><msup><mrow><mi mathvariant="normal">b</mi></mrow><mrow><mo>−</mo><mn>1</mn></mrow></msup></mrow></mrow></math>. A number of observables related to the overall distribution of charged particles in the collisions are corrected for detector effects and compared with simulations. Inclusive event-shape distributions, as well as differential distributions of event shapes as functions of charged-particle multiplicity, are studied. None of the models investigated are able to satisfactorily describe the data. Moreover, there are significant features common amongst all generator setups studied, particularly showing data being more isotropic than any of the simulations. Multidimensional unfolded distributions are provided, along with their correlations.

We use the mixed phase ensemble method—where the system is constrained so that half of the volume is in the confined phase and the other half in the deconfined phase—and the interface tension is obtained by measuring the capillary wave fluctuation spectra of the interfaces between the two phases. The method bypasses supercritical slowing down from which other methods for determining the interface tension suffer, and as a by-product produces accurate estimates of the critical inverse gauge coupling as a function of the inverse temperature. We use the latter to determine the lattice beta function values, required to compute the latent heat from the discontinuity in the average plaquette action across the confined-deconfined transition.

We show that the Seiberg-type duality of <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mrow><mi mathvariant="script">N</mi><mo>=</mo><mn>1</mn></mrow></math> gauge theory coupled with tensor chiral fields and fundamental chiral fields works if the meson spectrum built from the tensor fields takes a particular form: (a) It should be truncated. (b) The <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>R</mi></math> charges of tensor fields <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mo stretchy="false">{</mo><msub><mi>R</mi><mi>a</mi></msub><mo stretchy="false">}</mo></math> and the truncated mesons <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mo stretchy="false">{</mo><msub><mi>R</mi><mi>j</mi></msub><mo stretchy="false">}</mo></math> take very special values. The meson spectrum so that the duality works is encoded elegantly in the factorization of the polynomial <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><msup><mi>y</mi><mi>n</mi></msup><mo>−</mo><mn>1</mn><mo>=</mo><msub><mi mathvariant="normal">Φ</mi><mo>+</mo></msub><msub><mi mathvariant="normal">Φ</mi><mo>−</mo></msub></math>. Our consideration covers many known <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi mathvariant="script">N</mi><mo>=</mo><mn>1</mn></math> dualities and generates a large class of new examples.
