Isotope Spectroscopy [PDF]

open access: yesAstronomische Nachrichten, 2013
The measurement of isotopic ratios provides a privileged insight both into nucleosynthesis and into the mechanisms operating in stellar envelopes, such as gravitational settling.

SIMP Spectroscopy [PDF]

open access: yesJournal of High Energy Physics, 2016
We study the interactions between strongly interacting massive particle dark matter and the Standard Model via a massive vector boson that is kinetically mixed with the hypercharge gauge boson.

Dibaryon Spectroscopy [PDF]

open access: yesJournal of High Energy Physics, 2003
The AdS/CFT correspondence relates dibaryons in superconformal gauge theories to holomorphic curves in Kaehler-Einstein surfaces. The degree of the holomorphic curves is proportional to the gauge theory conformal dimension of the dibaryons. Moreover, the

Oscillon spectroscopy

open access: yesJournal of High Energy Physics, 2023
Abstract The sine-Gordon model in 3+1 dimensions is known to admit two oscillons of different energy and frequency but comparable lifetime. We show that the oscillon spectrum includes more spherically symmetric “states”. We identify new high-amplitude oscillons by allowing the field profile to have a number of nodes.

Ditauonium spectroscopy

open access: yesThe European Physical Journal C, 2022
AbstractWe examine the properties of ditauonium, an exotic atom consisting of a pair of opposite-sign $$\tau $$ τ leptons bound together by the quantum electrodynamics (QED) interaction in a hydrogen-like state. The energy levels, decay modes and associated partial widths, as well as total widths and lifetimes of the ...

Dual-comb optical activity spectroscopy for the analysis of vibrational optical activity induced by external magnetic field

open access: yesNature Communications, 2023
Dual-comb spectroscopy was first applied to the measurement of magnetic optical activity spectroscopy, realizing Doppler-limited gas-phase molecular analysis, and was further extended to the rapid measurement of liquid-phase chiroptical activity.

Tetraquark spectroscopy [PDF]

open access: yes, 2006
A complete classification of tetraquark states in terms of the spin-flavor, color and spatial degrees of freedom was constructed. The permutational symmetry properties of both the spin-flavor and orbital parts of the quark-quark and antiquark-antiquark ...

Intramolecular vibrational dynamics of ν1 mode in (CF3)2C=C=O molecule induced by resonant IR femtosecond radiation

open access: yesEPJ Web of Conferences, 2017
Intramolecular dynamics of the vibrational levels (up to v = 5) of the ν1 mode in (CF3)2CCO molecule, induced via multiphoton selective excitation of this mode by resonant femtosecond IR radiation, was studied.

Light Hadron Spectroscopy [PDF]

open access: yes, 1997
Recent developments in calculations of the light hadron spectrum are reviewed. Particular emphasis is placed on discussion of to what extent the quenched spectrum agrees with experiment.
