Compositeness test with nodal curves [PDF]

open access: yes, 2017
In this work, we present a use of nodal curves to detect the compositeness of a given odd integer n = 1. The method relies on the extension of Mumford representation and Cantor's algorithm for special singular ...

Anatomy of the newly observed hidden-charm pentaquark states: Pc(4312), Pc(4440) and Pc(4457)

open access: yesPhysics Letters B, 2019
We study the newly reported hidden-charm pentaquark candidates Pc(4312), Pc(4440) and Pc(4457) from the LHCb Collaboration, in the framework of the effective-range expansion and resonance compositeness relations.

Compositional Generalization Requires Compositional Parsers

open access: yesCoRR, 2022
A rapidly growing body of research on compositional generalization investigates the ability of a semantic parser to dynamically recombine linguistic elements seen in training into unseen sequences. We present a systematic comparison of sequence-to-sequence models and models guided by compositional principles on the recent COGS corpus (Kim and Linzen ...

Search for a heavy composite Majorana neutrino in events with dilepton signatures from proton-proton collisions at s=13 TeV

open access: yesPhysics Letters B, 2023
Results are presented of a search for a heavy Majorana neutrino Image 1 decaying into two same-flavor leptons ℓ (electrons or muons) and a quark-pair jet. A model is considered in which the Image 1 is an excited neutrino in a compositeness scenario.

« Composition, composition »…

open access: yesTransatlantica, 2013
Il s’agit de s’interroger sur ce qui se joue dans l’écriture littéraire et sur ce qui explique la difficulté qu’ont les non littéraires à saisir le travail de la langue et la composition esthétique de l’œuvre, lesquels assurent la puissance cognitive du texte littéraire et le distinguent fondamentalement des autres objets de fiction auquel il est ...

A remark on the compositeness criteria in the Lee model [PDF]

open access: yes, 1965
The compositeness criteria of Salam are investigated in a Lee model with two V-particles. It is shown that in the presence of two stable particles with identical quantum numbers the concept of compositeness loses its absolute ...

Addressing six standard model problems with Technically Natural Higgs models

open access: yesJournal of High Energy Physics, 2023
We aim to study the potential of the recently proposed model framework, called Technically Natural Higgs (TNH), in addressing six fundamental problems in particle physics and cosmology.

Improved Early Referral in Long‐Term Survivor Care With Institutional Standardized Practice Among Childhood Leukemia Survivors#

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT In 2018, the Texas Children's Cancer and Hematology Center Leukemia Program implemented a practice standard to support the transition from treatment to survivorship that includes shared, alternating care between leukemia and survivorship clinicians and a reminder to refer survivors to the long‐term survivor clinic (LTSC) 2 years after ...

Sigma-assisted low scale composite Goldstone–Higgs

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We show that the presence of a lightish scalar resonance, $$\sigma $$ σ , that mixes with the composite Goldstone–Higgs boson can relax the typical bounds found in this class of models.
