Exotic Atoms and Exotic Nuclei [PDF]

open access: yesActa Physica Polonica B, 2015
We briefly review the study of the exotic atoms and exotic nuclei, and report recent research activities of eta-mesic nucleus and kaonic atoms in this article.

Arthropod co-occurrence networks indicate environmental differences between islands and signal introduced species in Azorean native forest remnants

open access: yesFrontiers in Ecology and Evolution, 2023
Island biotas are in imminent threat from anthropogenic impacts. Of these impacts, the negative effects of exotic species on the taxonomic and functional diversity of the local fauna are of major concern.

Exotics at BESIII [PDF]

open access: yesEPJ Web of Conferences, 2019
With a collected integrated luminosity of about 12 fb−1, useful data set for XYZ new resonances, BESIII continues the exploration of these exotic charmonium-like states. In this proceeding, recent results on the measurements of the line-shape of e+e− → π+

Shifting dietary habits linked with contrasting population trends of two sympatric mustelids (Martes foina and Mustela putorius) over 16 years

open access: yesGlobal Ecology and Conservation, 2022
Despite widespread concern about biodiversity declines, few empirical studies exist on long-term population trends of mammal carnivores. In the context of global change, it is essential to understand the population trends and resource use of mammal ...

Exotic trees [PDF]

open access: yesPhysical Review E, 2003
We discuss the scaling properties of free branched polymers. The scaling behaviour of the model is classified by the Hausdorff dimensions for the internal geometry: d_L and d_H, and for the external one: D_L and D_H. The dimensions d_H and D_H characterize the behaviour for long distances while d_L and D_L for short distances. We show that the internal

On hypercharge flux and exotics in F-theory GUTs [PDF]

open access: yes, 2010
We study SU(5) Grand Unified Theories within a local framework in F-theory with multiple extra U(1) symmetries arising from a small monodromy group. The use of hypercharge flux for doublet-triplet splitting implies massless exotics in the spectrum that ...

Exotic Coactions [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 2016
AbstractIf a locally compact group G acts on a C*-algebra B, we have both full and reduced crossed products and each has a coaction of G. We investigate ‘exotic’ coactions in between the two, which are determined by certain ideals E of the Fourier–Stieltjes algebra B(G); an approach that is inspired by recent work of Brown and Guentner on new C*-group ...

Heavy Holographic Exotics: Tetraquarks as Efimov States [PDF]

open access: yes, 2019
We provide a holographic description of non-strange multiquark exotics as compact topological molecules by binding heavy-light mesons to a tunneling configuration in D8-D$\bar 8$ that is homotopic to the vacuum state with fixed Chern-Simons number.

QCD exotics [PDF]

open access: yesHyperfine Interactions, 2014
QCD-motivated models for hadrons predict an assortment of "exotic" hadrons that have structures that are more complex then the quark-antiquark mesons and three-quark baryons of the original quark-parton model. These include pentaquark baryons, the six-quark H-dibaryon, and tetra-quark, hybrid, and glueball mesons.

Gauge coupling unification and light Exotica in String Theory [PDF]

open access: yes, 2007
In this letter we consider the consequences for the LHC of light vector-like exotica with fractional electric charge. It is shown that such states are found in orbifold constructions of the heterotic string.
