Molecular components in the $J/ψ$ and the $ρ$-$π$ puzzle
Motivated by the large branching fractions of $J/ψ\to f_0 (1710) ω/f_0(1710) ϕ$ and the light exotic candidates, we find that there may exist molecular states composed of $f_0(1710) ω$ and $f_0 (1710) ϕ$, which correspond to $X(2440)$ and $X(2680)$ observed in a few decades before. The branching fraction of $X(2440)$ and $X(2680)$ to various $PV$ channels and $KKω(ϕ)$ channels are estimated in the molecular scenario. In addition, the large branching fractions of $J/ψ\to f_0 (1710) ω/f_…

Topology of a complex double plane branching along a real line arrangement
We investigate the topology of a double cover of a complex affine plane branching along a nodal real line arrangement. We define certain topological 2-cycles in the double plane using the real structure of the arrangement, and calculate their intersection numbers.

Coalgebraic Satisfiability Checking for Arithmetic $μ$-Calculi
The coalgebraic $μ$-calculus provides a generic semantic framework for fixpoint logics over systems whose branching type goes beyond the standard relational setup, e.g. probabilistic, weighted, or game-based. Previous work on the coalgebraic $μ$-calculus includes an exponential-time upper bound on satisfiability checking, which however relies on the availability of tableau rules for the next-step modalities that are sufficiently well-behaved in a formally defined sense; in particular, rule ma…

Branching Brownian motion versus Random Energy Model in the supercritical phase: overlap distribution and temperature susceptibility
In comparison with Derrida's REM, we investigate the influence of the so-called decoration processes arising in the limiting extremal processes of numerous log-correlated Gaussian fields. In particular, we focus on the branching Brownian motion and two specific quantities from statistical physics in the vicinity of the critical temperature. The first one is the two-temperature overlap, whose behavior at criticality is smoothened by the decoration process - unlike the one-temperature overlap whi…

The new $K_S \rightarrow πe ν$ branching fraction measurement at KLOE
A new measurement of the branching fraction for the decay $K_S \rightarrow πe ν$ is presented, based on a sample of 300 million $K_S$ mesons recorded by the KLOE experiment at the DA$Φ$NE $e^+e^-$ collider. A two-step signal selection strategy is used, exploiting first kinematic variables and then time-of-flight measurements. Data control samples of $K_S \rightarrow πe ν$ decays are used to evaluate signal selection efficiencies. Normalizing the selected sample to the number of $K_S \right…

Inclusive $\bar{B}\to X_s \ell^+\ell^-$ at the LHC: theory predictions and new-physics reach
We present theoretical predictions for observables in inclusive $\bar{B}\to X_s \ell^+\ell^-$ suitable for measurements at hadron colliders through a sum-over-exclusive approach. At low $q^2$ we calculate the branching ratio and three angular observables. At high $q^2$ we provide the branching ratio and the ratio of the $\bar B \to X_s \ell^+\ell^-$ rate with respect to the inclusive $\bar B \to X_u \ell \barν$ rate with the same phase-space cut. We compare our predictions to an extraction of …

Amplitude analysis and branching fraction measurement of $B^{+}\to D^{*-}D^{+}_{s}π^{+}$ decays
The decays of the $B^{+}$ meson to the final state $D^{*-}D^{+}_{s}π^{+}$ are studied in proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7, 8, and 13 TeV, corresponding to a total integrated luminosity of 9 fb$^{-1}$. The ratio of branching fractions of the $B^{+}\to D^{*-}D^{+}_{s}π^{+}$ and $B^{0}\to D^{*-}D^{+}_{s}$ decays is measured to be $0.173\pm 0.006\pm 0.010$, where the first uncertainty is statistical and the second is systematic. Using p…

Automata-Theoretic Characterisations of Branching-Time Temporal Logics
Characterisations theorems serve as important tools in model theory and can be used to assess and compare the expressive power of temporal languages used for the specification and verification of properties in formal methods. While complete connections have been established for the linear-time case between temporal logics, predicate logics, algebraic models, and automata, the situation in the branching-time case remains considerably more fragmented. In this work, we provide an automata-theoreti…

Optimised observables and new physics prospects in the penguin-mediated decays $B_{d(s)}\to K^{(*)0}ϕ$
We study the penguin-mediated decays $\bar{B}_{d(s)}\to\bar{K}^{*0}(K^{*0})ϕ$ transitions. We propose a new optimised observable $L_{K^*ϕ}$ from the ratio of longitudinal branching ratios of these decays, with limited hadronic uncertainties and enhanced sensitivity to New Physics. It exhibits a deviation at the $1.48\, σ$ level between its experimental value and its SM determination within QCD factorisation. This result can be accommodated together with the significant deviations found for t…

Charmonium decays of beauty baryons in the perturbative QCD approach
Motivated by recent advances in experimental measurements of heavy baryon decays, the charmonium decays of single $b$-baryon are investigated systematically in the framework of perturbative QCD approach. We calculate the decay branching ratios and helicity amplitudes as well as many pertinent decay asymmetry parameters that characterize the angular decay distributions. In particular, we estimate the fragmentation fractions of $b$ quark to $b$-baryons based on the current world averages of the b…
