An Underwater Passive Electric Field Positioning Method Based on Scalar Potential

Mathematics
In order to fulfill the practical application demands of precisely localizing underwater vehicles using passive electric field localization technology, we propose a scalar-potential-based method for the passive electric field localization of underwater ...

Quantum aspects of Yukawa model with scalar and axial scalar fields in curved spacetime

European Physical Journal C: Particles and Fields, 2019
We study the Yukawa model with one scalar and one axial scalar fields, coupled to N copies of Dirac fermions, in curved spacetime background. The theory possesses a reach set of coupling constants, including the scalar terms with odd powers of scalar ...

Higuchi bound on slow-roll inflation and the swampland

Journal of High Energy Physics, 2020
In this paper we study the implications of the generalized Higuchi bound on massive spin-two fields for the derivative of the scalar potential within bimetric theory.

The scalar chemical potential in cosmological collider physics

Journal of High Energy Physics, 2021
Non-analyticity in co-moving momenta within the non-Gaussian bispectrum is a distinctive sign of on-shell particle production during inflation, presenting a unique opportunity for the “direct detection” of particles with masses as large as the ...

Klein’s paradox in the presence of a scalar potential [PDF]

Modern Physics Letters A, 2019
In this paper, we have studied the Klein’s paradox in the presence of both scalar and vector potential barriers. From the corresponding Dirac equation, we have calculated the transmission and reflection coefficients. It is shown that the presence of a scalar barrier the scalar potential widens the gap between positive and negative energies and so the ...

Argumentando sobre a realidade dos potenciais

Revista Brasileira de Ensino de Física
Argumenta-se que, da mesma forma que o efeito Aharonov-Bohm mostrou ser o potencial vetor detetável microscopicamente, os nossos transformadores parecem indicar que ele o é macroscopicamente através de sua derivada temporal.

Non-perturbative fixed points and renormalization group improved effective potential

Physics Letters B, 2014
The stability conditions of a renormalization group improved effective potential have been discussed in the case of scalar QED and QCD with a colorless scalar.

Holographic RG and exact RG in O(N) model

Nuclear Physics B, 2020
In this paper an Exact Renormalization Group (ERG) equation is written for the critical O(N) model in D-dimensions (with D≈3) at the Wilson-Fisher fixed point perturbed by a scalar composite operator. The action is written in terms of an auxiliary scalar

A complex singlet extension of the standard model and multi-critical point principle

Physics Letters B, 2023
We study the Multi-critical Point Principle (MPP) in a complex singlet scalar extension of the Standard Model (CxSM). The MPP discussed in this study selects model parameters so that two low-energy vacua realized by scalar fields are degenerate.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
