The JWST FRESCO Survey:Legacy NIRCam/Grism Spectroscopy and Imaging in the two GOODS Fields
We present the JWST cycle 1 53.8 h medium program FRESCO, short for 'First Reionization Epoch Spectroscopically Complete Observations'. FRESCO covers 62 arcmin2 in each of the two GOODS/CANDELS fields for a total area of 124 arcmin2 exploiting JWST's powerful new grism spectroscopic capabilities at near-infrared wavelengths. By obtaining âŒ2 h deep NIRCam/grism observations with the F444W filter, FRESCO yields unprecedented spectra at R âŒ1600 covering 3.8-5.0 ÎŒm for most galaxies in the NIRCam field of view. This setup enables emission line measurements over most of cosmic history, from strong PAH lines at z âŒ0.2-0.5, to Pa α and Pa ÎČ at z âŒ1-3, He i and [S iii] at z âŒ2.5-4.5, H α and [N ii] at z âŒ5-6.5, up to [O iii] and H ÎČ for z âŒ7-9 galaxies. FRESCO's grism observations provide total line fluxes for accurately estimating galaxy stellar masses and calibrating slit-loss corrections of NIRSpec/MSA spectra in the same field. Additionally, FRESCO results in a mosaic of F182M, F210M, and F444W imaging in the same fields to a depth of âŒ28.2 mag (5Ï in 032 diameter apertures). Here, we describe the overall survey design and the key science goals that can be addressed with FRESCO. We also highlight several, early science results, including: spectroscopic redshifts of Lyman break galaxies that were identified almost 20 yr ago, the discovery of broad-line active galactic nuclei at z > 4, and resolved Pa α maps of galaxies at z âŒ1.4. These results demonstrate the enormous power for serendipitous discovery of NIRCam/grism observations.</p
The JWST FRESCO Survey: Legacy NIRCam/Grism Spectroscopy and Imaging in the two GOODS Fields
We present the JWST Cycle 1 53.8hr medium program FRESCO, short for "First
Reionization Epoch Spectroscopically Complete Observations". FRESCO covers 62
arcmin in each of the two GOODS/CANDELS fields for a total area of 124
arcmin exploiting JWST's powerful new grism spectroscopic capabilities at
near-infrared wavelengths. By obtaining ~2 hr deep NIRCam/grism observations
with the F444W filter, FRESCO yields unprecedented spectra at R~1600 covering
3.8 to 5.0 m for most galaxies in the NIRCam field-of-view. This setup
enables emission line measurements over most of cosmic history, from strong PAH
lines at z~0.2-0.5, to Pa and Pa at z~1-3, HeI and [SIII] at
z~2.5-4.5, H and [NII] at z~5-6.5, up to [OIII] and H for z~7-9
galaxies, and possibly even [OII] at z~10-12. FRESCO's grism observations
provide total line fluxes for accurately estimating galaxy stellar masses and
calibrating slit-loss corrections of NIRSpec/MSA spectra in the same field.
Additionally, FRESCO results in a mosaic of F182M, F210M, and F444W imaging in
the same fields to a depth of ~28.2 mag (5 in 0.32" diameter
apertures). Together with this publication, the v1 imaging mosaics are released
as high-level science products via MAST. Here, we describe the overall survey
design and the key science goals that can be addressed with FRESCO. We also
highlight several, early science results, including: spectroscopic redshifts of
Lyman break galaxies that were identified almost 20 years ago, the discovery of
broad-line active galactic nuclei at z>4, and resolved Pa maps of
galaxies at z~1.4. These results demonstrate the enormous power for
serendipitous discovery of NIRCam/grism observations. Given the wealth of
ancillary data available in these fields, the zero-proprietary time FRESCO data
is poised to enable a large amount of legacy science by the community.Comment: 11 pages, 11 figures; submitted to MNRAS; for more information on the

Measurement of the phase difference between short- and long-distance amplitudes in the decay
A measurement of the phase difference between the short- and long-distance
contributions to the decay is performed by
analysing the dimuon mass distribution. The analysis is based on collision
data corresponding to an integrated luminosity of 3 collected by
the LHCb experiment in 2011 and 2012. The long-distance contribution to the
decay is modelled as a sum of relativistic
Breit--Wigner amplitudes representing different vector meson resonances
decaying to muon pairs, each with their own magnitude and phase. The measured
phases of the and resonances are such that the interference
with the short-distance component in dimuon mass regions far from their pole
masses is small. In addition, constraints are placed on the Wilson
coefficients, and , and the branching
fraction of the short-distance component is measured.Comment: 23 pages, 4 figures, published in EPJC. All figures and tables, along
