Sensitivity enhancement techniques for cryogenic calorimeters in the NUCLEUS experiment
M. Cappelli, A. Wallach, H. Abele +62
Phonon-mediated cryogenic calorimeters find application in rare event searches due to their intrinsically low energy threshold. Achieving the best sensitivity for this kind of dete…
The two-loop five-particle amplitude in supergravity
D. Chicherin, T. Gehrmann, J. M. Henn +3
We compute for the first time the two-loop five-particle amplitude in supergravity. Starting from the known integrand, we perform an integration-by-parts reduction…
Observation of two nuclear recoil peaks induced by neutron capture on Al2O3
H. Abele, P. Ajello, B. Arnold +43
We report the observation of two nuclear recoil peaks induced by neutron capture on aluminum in a cryogenic AlO detector developed by the NUCLEUS collaboration for the dete…
Analytic form of the full two-loop five-gluon all-plus helicity amplitude
S. Badger, D. Chicherin, T. Gehrmann +6
We compute the full-color two-loop five-gluon amplitude for the all-plus helicity configuration. In order to achieve this, we calculate the required master integrals for all permut…
Characterization of the Low Energy Excess using a NUCLEUS detector
H. Abele, G. Angloher, B. Arnold +62
The NUCLEUS experiment aims to detect coherent elastic neutrino-nucleus scattering of reactor antineutrinos using low-threshold, gram-scale cryogenic calorimeters. Similar to other…
Prospect of the NUCLEUS Experiment at Chooz for Coherent Elastic Neutrino-Nucleus Scattering and New Physics Searches
H. Abele, G. Angloher, B. Arnold +67
The NUCLEUS experiment aims to measure coherent elastic neutrino-nucleus scattering (CENS) at unprecedentedly low nuclear recoil energies using gram-scale cryogenic calorimeters…
Analytic result for the nonplanar hexa-box integrals
D. Chicherin, T. Gehrmann, J. M. Henn +3
In this paper, we analytically compute all master integrals for one of the two non-planar integral families for five-particle massless scattering at two loops. We first derive an i…
All master integrals for three-jet production at NNLO
D. Chicherin, T. Gehrmann, J. M. Henn +3
We evaluate analytically all previously unknown nonplanar master integrals for massless five-particle scattering at two loops, using the differential equations method. A canonical…
The CRAB facility at the TU Wien TRIGA reactor: status and related physics program
H. Abele, P. Ajello, A. Armatol +51
The CRAB (Calibrated nuclear Recoils for Accurate Bolometry) project aims to precisely characterize the response of cryogenic detectors to sub-keV nuclear recoils of direct interes…
Analytic result for a two-loop five-particle amplitude
D. Chicherin, T. Gehrmann, J. M. Henn +3
We compute the symbol of the full-color two-loop five-particle amplitude in super Yang-Mills, including all non-planar subleading-color terms. The amplitude is writ…
