Search for the eta c
… Brookhaven National Laboratory, we searched for narrow resonances in the reaction pi minus p -> X n, X -> gamma gamma at 13 Gev. We used a double arm spectrometer with lead glass and scintillation elements. No resonances were observed above mass 2.8 in the gamma gamma spectrum. The upper limit …

Exploring New Frontiers in High Energy Physics: Boosted Resonances Decaying To Quarks, Foundation Models, and Heterogeneous Computing at the CMS Experiment
… searches for new physics, for example, low mass resonances decaying to quarks. In this context, a search for narrow resonances decaying into quarkantiquark pairs produced with high transverse momentum is presented. The analysis is based on data collected in Run 2 with the CMS detector at the LHC …

Search for pentaquark partners [Theta]⁺⁺, [Sigma]⁰ and N⁰ in H (e,e'K [pi])) X reactions at Jefferson Lab Hall A
… prediction using this symmetry group is a narrow exotic state, E+(1540), which has quark component uuddg. If such a state is confirmed, other members of the antide cuplet could be expected to have sufficiently narrow widths to be observed as well. The Jefferson Laboratory experiment E04-012 …

Improved Search for Heavy Neutral Scalars A and H Using ttZ Events from 13 TeV pp Collisions at CMS
… allowing reconstruction of the heavy resonances. No evidence for a signal is observed. Model-independent upper limits on the product of cross section and branching fraction are set for A masses from 430 to 2100 GeV and H masses from 330 to 2000 GeV, assuming narrow resonances. The …

NMR spectroscopy in the presence of ultrasound and other perturbations
… and spin-spin coupling, that are evident in the narrow resonances, arising from some of the nuclear broadening interactions being reduced to zero. In the solid state, all of the nuclear broadening interactions are present and broad lines in the NMR spectrum are observed. Current techniques …
