T-matrix analysis of pion-proton femtoscopy

This paper investigates the observed shift of the Δ(1232)\Delta(1232) resonance peak in pion-proton femtoscopic correlations by applying a T-matrix approach within the Koonin-Pratt framework to reveal how the finite emission source induces off-shell dynamics, though the model's inability to fully reproduce experimental correlation strength and the absence of a predicted high-momentum dip suggest the need for more complex source descriptions beyond a simple spherical Gaussian approximation.

Impact of N∗N^* and Λ∗\Lambda^* resonances on CPCP violation in Λb0\Lambda_b^0 decays

This paper utilizes the constituent quark model to establish a comprehensive framework demonstrating that excited nucleon (N∗N^*) and hyperon (Λ∗\Lambda^*) resonances are the key drivers behind the first observed baryonic CPCP violation in the four-body decay Λb0→pK−π+π−\Lambda_b^0\to pK^-\pi^+\pi^-, successfully reproducing the measured branching fraction and CPCP asymmetry.

Probing Signatures of Right-Handed Neutrinos via b→sννˉb \to s \nu \bar\nu Decays

Motivated by the recent Belle II measurement of B+→K+ννˉB^+\to K^+\nu\bar{\nu}, this paper employs a model-independent effective field theory analysis to constrain right-handed neutrino interactions and predicts correlated enhancements in various b→sννˉb\to s\nu\bar{\nu} branching fractions and polarization observables as testable signatures for future experiments.

Machine learning unveils the quark mass dependence of the pseudoscalar meson decay constants in three-flavour N2^2LO ChPT

This paper utilizes the LASSO machine learning method to analyze recent LQCD data within three-flavor N2^2LO Chiral Perturbation Theory, precisely determining the quark mass dependence of pseudoscalar meson decay constants up to 780 MeV and applying these results to predict octet baryon masses in the SU(3) limit.

The Muon and Tau Electric Dipole Moments in the B-L Supersymmetric Standard Model

This paper investigates the electric dipole moments of muons and taus within the B-L supersymmetric standard model, demonstrating that both the traditional μ\mu-term and model-specific CP-violating parameters can produce significant contributions, with muon EDMs potentially falling within the sensitivity of upcoming Phase II experiments and tau EDMs reaching magnitudes around 10−21e⋅cm10^{-21}e\cdot\text{cm}.

Five-flavor udscbˉudsc\bar{b} molecular pentaquarks from heavy-quark and local hidden gauge symmetries

This paper predicts the existence of ten narrow, isoscalar five-flavor (udscbˉudsc\bar{b}) molecular pentaquark states in the 7.72–7.96 GeV range, along with two additional deeply bound states, by applying local hidden gauge and heavy-quark symmetries to meson-baryon interactions, thereby extending previous hidden-charm studies to the bottom sector and offering specific targets for LHCb searches.

Global Ab initio Neutrino Mass Limits from Neutrinoless Double-Beta Decay

This paper presents global Bayesian limits on Majorana neutrino masses by combining latest neutrinoless double-beta decay experimental data with ab initio nuclear matrix elements, revealing that current experiments likely lack the sensitivity to probe the neutrino mass regime allowed by oscillation data while demonstrating that next-generation searches across four key isotopes could collectively cover the inverted mass ordering.
