Non-Gaussianity effects on the primordial black hole abundance for sharply-peaked primordial spectrum

Kavli Affiliate: Misao Sasaki | First 5 Authors: Takahiko Matsubara, Misao Sasaki, , , | Summary: We perturbatively study the effect of non-Gaussianities on the mass fraction of primordial black holes (PBHs) at the time of formation by systematically taking its effect into account in the one-point probability distribution function of the primordial curvature perturbation. […]

Monojet signatures from gluino and squark decays

Kavli Affiliate: Mihoko M. Nojiri | First 5 Authors: Iñaki Lara, Trygve Buanes, Rafał Masełek, Mihoko M. Nojiri, Krzysztof Rolbiecki | Summary: In this paper, we study the monojet and dijet channels at the LHC as a tool for searching for squarks and gluinos. We consider two separate scenarios. In the first scenario we postulate […]

Conserved charges in the quantum simulation of integrable spin chains

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Kazunobu Maruyoshi, Takuya Okuda, Juan William Pedersen, Ryo Suzuki, Masahito Yamazaki | Summary: When simulating the time evolution of quantum many-body systems on a digital quantum computer, one faces the challenges of quantum noise and of the Trotter error due to time discretization. The Trotter error in […]

Testing magnetic interference between TES detectors and the telescope environment for future CMB satellite missions

Kavli Affiliate: Nobuhiko Katayama | First 5 Authors: Tommaso Ghigna, Thuong Duc Hoang, Takashi Hasebe, Yurika Hoshino, Nobuhiko Katayama | Summary: The two most common components of several upcoming CMB experiments are large arrays of superconductive TES (Transition-Edge Sensor) detectors and polarization modulator units, e.g. continuously-rotating Half-Wave Plates (HWP). A high detector count is necessary […]

Highly non-Gaussian tails and primordial black holes from single-field inflation

Kavli Affiliate: Misao Sasaki | First 5 Authors: Yi-Fu Cai, Xiao-Han Ma, Misao Sasaki, Dong-Gang Wang, Zihan Zhou | Summary: For primordial perturbations, deviations from Gaussian statistics on the tail of the probability distribution can be associated with non-perturbative effects of inflation. In this paper, we present some particular examples in which the tail of […]
