“…Since the potential is Starobinsky-like, the tensor-to-scalar ratio r 3 × 10 −3 , well within the range allowed by the Planck and other data [12]. This prediction can be tested in future CMB experiments such as CMB-S4 [20] and LiteBIRD [21]. Additionally, as we discuss later, the predicted value of the tilt in the scalar perturbation spectrum, n s is also within the range favoured by Planck and other data at the 68% CL.…”

“…(26) does have a connection with U ν c via Eqs. (21) and (22), due to the presence of an extra unknown matrix, U l , we cannot predict the PMNS matrix in our model. In particular, the determination of neutrino CP phases at low energies has no implication on the CP phases relevant to leptogenesis (i.e., the phases in the matrix U ν c ) 10 .…”

“…We note that, given a matrix λ ia 6 , the eigenvalues of the m ν and m ν c matrices, as well as the mixing matrices U ν c and U ν , are uniquely determined as functions of µ 1 and µ 2 via Eqs. (19)(20)(21).…”

“…Since these operators are generated in the same manner as the neutrino mass matrix in Eq. (21), in the bases where the neutrino mass matrix is diagonalized, the dimension-five operators can be written as m i L i L ihh / h 0 2 , with m i (i = 1, 2, 3) the mass eigenvalues of the light neutrinos. These operators decouple from the thermal bath at the time of the GUT phase transition for m i 0.2 eV, which is the case in our scenario, as we see in the next Section.…”

We develop a string-inspired model for particle cosmology, based on a flipped SU(5)×U(1) gauge group formulated in a no-scale supergravity framework. The model realizes Starobinsky-like inflation, which we assume to be followed by strong reheating, with the GUT symmetry being broken subsequently by a light 'flaton' field whose decay generates a second stage of reheating. We discuss the production of gravitinos and the non-thermal contribution made by their decays to the density of cold dark matter, which is assumed to be provided by the lightest neutralino. We also discuss the masses of light and heavy neutrinos and leptogenesis. As discussed previously [1], a key rôle is played by a superpotential coupling between the inflaton, matter and GUT Higgs fields, called λ 6 . We scan over possible values of λ 6 , exploring the correlations between the possible values of observables. We emphasize that the release of entropy during the GUT transition allows large regions of supersymmetry-breaking parameter space that would otherwise lead to severe overdensity of dark matter. Furthermore, we find that the Big Bang nucleosynthesis lower limit on the reheating temperature of ∼ 1 MeV restricts the supersymmetry-breaking scale to a range O(10) TeV that is consistent with the absence of supersymmetric particles at the LHC.

“…A typical array consists of hundreds or thousands of membraneisolated superconducting transition-edge sensors (TESs) [2] photolithographically patterned onto a common silicon wafer, each coupled to incident radiation via feedhorns [3], lenses [4], or synthesized antennas [5]. Integrated bolometer arrays are a key enabling technology for a number of proposed space-based astronomical instruments [6][7][8][9].…”

Future mm-wave and sub-mm space missions will employ large arrays of multiplexed Transition Edge Sensor (TES) bolometers. Such instruments must contend with the high flux of cosmic rays beyond our atmosphere that induce 'glitches' in bolometer data, which posed a challenge to data analysis from the Planck bolometers. Future instruments will face the additional challenges of shared substrate wafers and multiplexed readout wiring. In this work we explore the susceptibility of modern TES arrays to the cosmic ray environment of space using two data sets: the 2015 long-duration balloon flight of the SPI-DER cosmic microwave background polarimeter, and a laboratory exposure of SPIDER flight hardware to radioactive sources. We find manageable glitch rates and short glitch durations, leading to minimal effect on SPIDER analysis. We constrain energy propagation within the substrate through a study of multi-detector coincidences, and give a preliminary look at pulse shapes in laboratory data.
