“…The EM Dalitz decays of the light unflavored mesons ρ, ω, and ϕ have been intensively studied by the CMD2, SND, NA60, and KLOE experiments [11][12][13][14][15]. For the decays of ϕ → ηe þ e − and ω → π 0 e þ e − , the branching fractions and slopes of the form factors Λ −2 are measured [12][13][14][15], and the results are in agreement with VMD predictions.…”

Based on a sample of ð225.3 AE 2.8Þ × 10 6 J=ψ events collected with the BESIII detector, the electromagnetic Dalitz decays of J=ψ → Pe þ e − ðP ¼ η 0 =η=π 0 Þ are studied. By reconstructing the pseudoscalar mesons in various decay modes, the decays J=ψ → η 0 e þ e − , J=ψ → ηe þ e − , and J=ψ → π 0 e þ e − are observed for the first time. The branching fractions are determined to be BðJ=ψ → η 0 e þ e − Þ ¼ ð5.81 AE 0.16 AE 0.31Þ × 10 −5 , BðJ=ψ → ηe þ e − Þ ¼ ð1.16 AE 0.07 AE 0.06Þ × 10 −5 , and BðJ=ψ → π 0 e þ e − Þ ¼ ð7.56 AE 1.32 AE 0.50Þ × 10 −7 , where the first errors are statistical and the second ones systematic.

“…Synthetic optical holography (SOH) is a recently introduced holographic modality of quantitative phase imaging in s-SNOM, , confocal microscopy, , and scanning cavity microscopy. , SOH was originally developed for s-SNOM imaging at a single laser line (single-frequency SOH) and forms the foundation for nano-FTIR holography. Briefly, in single-frequency SOH, the AFM tip is illuminated with light from a gas laser or QCL (Figure a).…”

Rapid Infrared Spectroscopic Nanoimaging with nano-FTIR Holography

et al. 2020

Scattering-type scanning near-field optical microscopy (s-SNOM), and its derivate, Fourier transform infrared nanospectroscopy (nano-FTIR) are emerging techniques for infrared (IR) nanoimaging and spectroscopy with applications in diverse fields ranging from nanophotonics, chemical imaging and materials science. However, spectroscopic nanoimaging is still challenged by the limited acquisition rate of current nano-FTIR technology. Here we combine s-SNOM, nano-FTIR and synthetic optical holographic (SOH) to achieve infrared spectroscopic nanoimaging at unprecedented speed (8 spectroscopically resolved images in 20 min), which we demonstrate with a polymer composite sample. Beyond being fast, our method promises to enable nanoimaging in the long IR spectral range, which is covered by IR supercontinuum and synchrotron sources, but not by current quantum cascade laser technology.

“…Recently, synthetic optical holography (SOH) [30] was introduced for quantitative phase imaging in near-field [30], confocal [31] and scanning microcavity [32] microscopy that take advantage of the mutual information between pixels and encodes amplitude and phase information across the image in the spirit of wide-field holography. In SOH, the scattered field from the focus or scanning probe is superposed with a reference wave with a linear-in-time phase function.…”

Accessible quantitative phase imaging in confocal microscopy with sinusoidal-phase synthetic optical holography

We present a technically simple implementation of quantitative phase imaging in confocal microscopy based on synthetic optical holography with sinusoidal-phase reference waves. Using a Mirau interference objective and low-amplitude vertical sample vibration with a piezo-controlled stage, we record synthetic holograms on commercial confocal microscope (Nikon, model: A1R; Zeiss: model: LSM-880), from which quantitative phase images are reconstructed. We demonstrate our technique by stain-free imaging of cervical (HeLa), ovarian (ES-2) cancer cells and stem cell (mHAT9a) samples. Our technique has the potential to extend fluorescence imaging applications in confocal microscopy by providing label-free cell finding, monitoring cell morphology as well as non-perturbing long-time observation of live cells based on quantitative phase contrast.
