Search for light long-lived neutral particles that decay to collimated pairs of leptons or light hadrons in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for light long-lived neutral particles with masses in the O(MeV–GeV) range is presented. The analysis targets the production of long-lived dark photons in the decay of a Higgs boson produced via gluon–gluon fusion or in association with a W ...

Charge Transfer States in Donor–Acceptor Bulk‐Heterojunctions as Triplet–Triplet Annihilation Sensitizer for Solid‐State Photon Upconversion

open access: yesAdvanced Materials Interfaces, EarlyView.
A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to

Search for a right-handed W boson and a heavy neutrino in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2022
A search is presented for a right-handed W boson (WR) and a heavy neutrino (N), in a final state consisting of two same-flavor leptons (ee or μμ) and two quarks.

Heavy exotic molecules [PDF]

open access: yesInternational Journal of Modern Physics E, 2017
We briefly review the formation of pion-mediated heavy-light exotic molecules with both charm and bottom, under the general structures of chiral and heavy quark symmetries. The charm isosinglet exotic molecules with [Formula: see text] binds, which we identify as the reported neutral [Formula: see text]. The bottom isotriplet exotic with [Formula: see

LHCb results on exotics and pentaquark states

open access: yesEPJ Web of Conferences, 2016
The latest years have seen a resurrection of interest in searches for exotic states. Using the data collected at pp collisions at 7 and 8 TeV by the LHCb experiment, unambiguous new observations of exotic charmonia hadrons produced in B and Λb decays are

Materials from the mycoflora of Szczecin

open access: yesActa Mycologica, 2014
The central Szczecin Cemetery is an object of dendrological importance because it contain above 360 species or varieties of trees and shrubs, a number of which are exotics in the flora of Poland. 136 species of fungi, mostly parasites,have been collected

Constraining Exotic Interactions [PDF]

open access: yesAnnalen der Physik, 2018
AbstractBeyond‐the‐standard‐model interactions mediated by an exchange of virtual “new” bosons result in a finite set of possible effective interaction potentials between standard‐model particles such as electrons and nucleons. The classification of such potentials is discussed and recent experiments searching for such exotic interactions at spatial ...

Ultra‐Thin Soft Pneumatic Actuation for Minimally Invasive Neural Interfacing

open access: yesAdvanced Materials Technologies, EarlyView.
Parylene C is a common polymer in bioelectronics, favored for its biological and chemical inertness. However, this makes bonding layers of Parylene C together very challenging. Here it is a laser to selectively weld layers of Parylene C to create high‐pressure fluidic actuation devices.

Layer‐Dependent Antiferromagnetic Chern and Axion Insulating States in UOTe

open access: yesAdvanced Science, EarlyView.
Layer‐dependent topological phases are identified in the van der Waals antiferromagnet UOTe. Ab initio calculations reveal bilayer UOTe as a rare example of high‐temperature antiferromagnetic Chern insulator with quantized Hall conductivity and near‐zero net magnetization, while odd‐layer films exhibit axion‐insulator‐like behavior with quantized spin ...
