Standard estimators cannot represent fault-tolerant workloads at measured error rates: evaluated, evidence-based uncertainty for quantum resource estimation
Furqan Nasir, Sher Jeel Ahmad
Estimates of the quantum resources needed to run fault-tolerant algorithms are almost always reported as single numbers, even though they rest on uncertain hardware parameters and…
Formation of Supermassive Black Hole Seeds from Vacuum-Dependent Thermal Dark Matter
Masahiro Kawasaki, Jie Sheng, Tsutomu T. Yanagida
The origin of supermassive black holes, especially those already present at high redshift, remains an open problem. We propose that their seeds are primordial black holes formed fr…
From the LZ Event to Grand Unification: Heavy Higgsinos and Proton Decay
Shihwen Hor, Natsumi Nagata, Tsutomu T. Yanagida
The recently reported LUX-ZEPLIN (LZ) event has renewed interest in inelastic Higgsino dark matter. While a weak-scale Higgsino provides a simple interpretation of the event, such…
Seesaw and Axion in No-Scale Gravity
Anamaria Hell, Lincoln da S. Pereira, Tsutomu T. Yanagida
The No-Scale gravity is a compelling framework to describe particle physics, gravity and cosmology, in which all mass scales are an illusion given by the value of a scalar field $ϕ…
Interacting Dark Energy and Dark Matter in O(3) No-Scale Gravity
Lincoln da S. Pereira, Muzi Hong, Elisa G. M. Ferreira +1
Dark Energy (DE) and Dark Matter (DM) are among the greatest mysteries in particle physics and cosmology, since their origins remain unclear. It is intriguing to consider whether b…
Minimal Majoron Dark Matter from a Discrete Gauge Symmetry
Subaru Fujisawa, Qiuyue Liang, Shigeki Matsumoto +2
We investigate majoron dark matter in a minimal setup, where the Standard Model is extended by three right-handed neutrinos and a complex scalar field. The theory is defined by an…
High-Quality Axion Dark Matter without Isocurvature Problem
Masahiro Kawasaki, Jie Sheng, Tsutomu T. Yanagida
Axion dark matter in high-scale inflation is subject to the isocurvature constraint, since quantum fluctuations of the axion field during inflation may exceed the current CMB bound…
Probing Majoron Dark Matter with Gravitational Wave Detectors
Ippei Obata, Tsutomu T. Yanagida
The Majoron is a hypothetical (pseudo) Nambu-Goldstone boson arising from the spontaneous breaking of a global lepton number symmetry, and is known as a candidate for dark matter i…
WIMP Dark Matter from a Natural Discrete Gauge Symmetry in the Standard Model
Jie Sheng, Tsutomu T. Yanagida, Kairui Zhang
The internal structure of the Standard Model implies a natural discrete gauge symmetry. Cancellation of the corresponding Dai--Freed anomalies re…
