Dimension theory for generalized effect algebras [PDF]

Algebra universalis, 2013
In this paper we define and study dimension generalized effect algebras (DGEAs), i.e., Dedekind orthocomplete and centrally orthocomplete generalized effect algebras equipped with a dimension equivalence relation. Our theory is a bona fide generalization of the theory of dimension effect algebras (DEAs), i.e., it is formulated so that, if a DGEA ...

Soft-gluon effective coupling and cusp anomalous dimension

European Physical Journal C: Particles and Fields, 2019
We consider the extension of the CMW soft-gluon effective coupling [1] in the context of soft-gluon resummation for QCD hard-scattering observables beyond the next-to-leading logarithmic accuracy.

Running of effective dimension and cosmological entropy in early universe

European Physical Journal C: Particles and Fields, 2020
In this paper, we suggest that the early universe starts from a high-energetic state with a two dimensional description and the state recovers to be four dimensional when the universe evolves into the radiation dominated phase.

Low-Energy Effective Field Theory below the Electroweak Scale: dimension-8 operators

Journal of High Energy Physics, 2021
We construct a complete basis of dimension-8 operators in the Low-Energy Effective Field Theory below the Electroweak Scale (LEFT). We find there are 35058 dimension-8 operators in the LEFT for two generations of up-type quarks and three generations of ...

The effective teacher: definition and main aspects in the educational research

Formare, 2016
For fostering a significant learning process, the teacher has a relevant role, as a co-protagonist with the student in the educational process. For this reason, many studies in the educational field have tried to examine the main characteristics of the ...

Dimension-8 SMEFT matching conditions for the low-energy effective field theory

Journal of High Energy Physics, 2023
In particle physics, the modern view is to categorize things in terms of effective field theories (EFTs). Above the weak scale, we have the SMEFT, formed when the heavy new physics (NP) is integrated out, and for which the Standard Model (SM) is the ...

On effective spacetime dimension in the Hořava–Lifshitz gravity

Physics Letters B, 2015
In this manuscript we explicitly compute the effective dimension of spacetime in some backgrounds of Hořava–Lifshitz (H–L) gravity. For all the cases considered, the results are compatible with a dimensional reduction of the spacetime to d+1=2, at high ...

Generalized Efimov Effect in One Dimension

Physical Review Letters, 2015
We study a one-dimensional quantum problem of two particles interacting with a third one via a scale-invariant subcritically attractive inverse square potential, which can be realized, for example, in a mixture of dipoles and charges confined to one dimension.
