Ultra-light dark matter with non-canonical kinetics reopening the mass window
Shiyun Lu, Amara Ilyas, Xiao-Han Ma +3
Fuzzy dark matter (FDM) with mass around eV is viewed as a promising paradigm in understanding the structure formation of the local universe at small scales. Recent obse…
MLAnalysis: An open-source program for high energy physics analyses
Yu-Chen Guo, Fan Feng, An Di +2
We present a python-based program for phenomenological investigations in particle physics using machine learning algorithms, called \verb"MLAnalysis". The program is able to conver…
Axion Isocurvature Collider
Shiyun Lu
Cosmological colliders can preserve information from interactions at very high energy scale, and imprint them on cosmological observables. Taking the squeezed limit of cosmological…
Cosmological Signatures of Superheavy Dark Matter
Lingfeng Li, Shiyun Lu, Yi Wang +1
We discuss two possible scenarios, namely the curvaton mechanism and the dark matter density modulation, where non-Gaussianity signals of superheavy dark matter produced by gravity…
A Cosmological Higgs Collider
Shiyun Lu, Yi Wang, Zhong-Zhi Xianyu
The quantum fluctuations of the Higgs field during inflation could be a source of primordial density perturbations through Higgs-dependent inflaton decay. By measuring primordial n…
Connections between Minkowski and Cosmological Correlation Functions
Shek Kit Chu, Mang Hei Gordon Lee, Shiyun Lu +3
We show how cosmological correlation functions of massless fields can be rewritten in terms of Minkowski correlation functions, by extracting symmetry-breaking operators from the c…
Differentiating G-inflation from String Gas Cosmology using the Effective Field Theory Approach
Minxi He, Junyu Liu, Shiyun Lu +4
A characteristic signature of String Gas Cosmology is primordial power spectra for scalar and tensor modes which are almost scale-invariant but with a red tilt for scalar modes but…
