Jet-associated resonance spectroscopy
We present a model-independent study aimed at characterising the nature of possible resonances in the jetphoton or jet-Z final state at hadron colliders. Such resonances are expected in many models of compositeness and would be a clear indication of new physics. At leading order, in the narrow width approximation, the matrix elements are parameterised by just a few constants describing the coup...
متن کاملDYE JET VELOCITY DISTRIBUTION MEASUREMENTS USING PHOTOTHERMAL DEFLECTION SPECTROSCOPY
We demonstrate that photothermal deflection spectroscopy can be used to measure velocity distributions in dye jets. Such measurements are useful in determining the quality of flow in dye jets, The quality of jets is very important for a stable and naanow linewidth operation of dye lasers
متن کاملKerr Gated Resonance Raman Spectroscopy In Light Fastness Studies Of Ink Jet Prints
Resonance Raman spectroscopy offers several advantages in the studies of ink jet prints stemming from its inherent selectivity and sensitivity. These include the possibility to obtain direct information on the chemical interactions between the paper and ink that play a major role in long-term print fastness. However, resonance Raman techniques can suffer from obtrusive fluorescence from coloran...
متن کاملTautomers and electronic states of jet-cooled 2-aminopurine investigated by double resonance spectroscopy and theory.
We present resonant two-photon ionization (R2PI), IR-UV, and UV-UV double resonance spectra of jet-cooled 2-aminopurine (2AP) as well as Fourier transform infrared (FTIR) gas phase spectra. 2AP is a fluorescing isomer of the nucleobase adenine. The results show that there is only one tautomer of 2AP which absorbs in the wavelength range 32,300-34,500 cm(-1). The comparison with the calculated I...
متن کاملElectronic spectroscopy of jet-cooled YbNH3.
We report the first spectroscopic study of a complex consisting of a rare earth atom in combination with ammonia. Using two-color resonance-enhanced multiphoton ionization (REMPI) spectroscopy, the lowest energy electronic transition of YbNH(3) has been found in the near-infrared. The spectrum arises from a spin-forbidden transition between the (1)A(1) ground electronic state and the lowest (3)...
