Exploring the flavor structure of quarks and leptons with reinforcement learning
Journal of High Energy Physics, 2023 We propose a method to explore the flavor structure of quarks and leptons with reinforcement learning. As a concrete model, we utilize a basic value-based algorithm for models with U(1) flavor symmetry.

Entropy, 2023 The geometric first-order integer-valued autoregressive process (GINAR(1)) can be particularly useful to model relevant discrete-valued time series, namely in statistical process control.

2020 global reassessment of the neutrino oscillation picture
Journal of High Energy Physics, 2021 We present an updated global fit of neutrino oscillation data in the simplest three-neutrino framework. In the present study we include up-to-date analyses from a number of experiments.

Neutrino cosmology after DESI: tightest mass upper limits, preference for the normal ordering, and tension with terrestrial observations [PDF]
Journal of Cosmology and Astroparticle PhysicsThe recent DESI Baryon Acoustic Oscillation measurements have led to tight upper limits on the neutrino mass sum, potentially in tension with oscillation constraints requiring ∑ mν ≳ 0.06 eV.

Possibilities of Future Double Beta Decay Experiments to Investigate Inverted and Normal Ordering Region of Neutrino Mass [PDF]
Frontiers of Physics, 2019 An overview of modern experiments on the search for neutrinoless double decay is presented. The obtained limits on the effective mass of the Majorana neutrino $\langle m_{\nu} \rangle$ are discussed taking into account the uncertainties in the value of ...

Crucial Dependence of ``Precarious'' and ``Autonomous'' phi^4s Upon the Normal-ordering Mass [PDF]
, 1999 Using the Gaussian wave-functional approach with the normal-ordering renormalization prescription, we show that for the (3+1)-dimensional massive lambda phi^4 theory, ``precarious'' and ``autonomous'' phi^4s can exist if and only if the normal-ordering ...

Order-cushioned refinements and normality [PDF]
Proceedings of the American Mathematical Society, 1982 The authors use the notions of order-cushioned covers and weak 0-covers to obtain the following result. THEOREM. A space X is collectionwise normal iff every weak 6-cover of X has an order-cushioned open refinement. Similar characterizations are obtained for normal, countably paracompact spaces and analogous embedding theorems are shown.

An ordering of normal ultrafiltres [PDF]
Fundamenta Mathematicae, 1985 Summary: Suppose \(\kappa\) is supercompact, and \(\lambda\geq \kappa\). Let \(Nuf_{\kappa}(\lambda)\) be the collection of all normal ultrafilters on \(P_{\kappa}(\lambda)\). For any \(U\in Nuf_{\kappa}(\lambda)\), let \(i_ u\) be the elementary embedding associated with U. Def.

NORMALLY ORDERED SEMIGROUPS [PDF]
Glasgow Mathematical Journal, 2008 AbstractIn this paper we introduce the notion of normally ordered block-group as a natural extension of the notion of normally ordered inverse semigroup considered previously by the author. We prove that the classNOSof all normally ordered block-groups forms a pseudovariety of semigroups and, by using the Munn representation of a block-group, we deduce

Self-duality, helicity conservation, and normal ordering in nonlinear QED [PDF]
Physical Review D, 2018 We give a proof of the equivalence of the electric-magnetic duality on one side and helicity conservation of the tree level amplitudes on the other side within general models of nonlinear electrodynamics.
