CMB limits on decaying dark matter beyond the ionization threshold

Clara Xu, Wenzer Qin, Tracy R. Slatyer

The temperature and polarization anisotropies of the cosmic microwave background (CMB) have been used to set constraints on decaying dark matter models down to keV masses. In this…

Birth of the first stars amidst decaying and annihilating dark matter

Wenzer Qin, Julian B. Munoz, Hongwan Liu +1

The first stars are expected to form through molecular-hydrogen (H $_{2}$ ) cooling, a channel that is especially sensitive to the thermal and ionization state of gas, and can thus act…

Exotic energy injection in the early universe II: CMB spectral distortions and constraints on light dark matter

Hongwan Liu, Wenzer Qin, Gregory W. Ridgway +1

We calculate the post-recombination contribution to the Cosmic Microwave Background (CMB) spectral distortion due to general exotic energy injections, including dark matter (DM) de…

Exotic energy injection in the early universe I: a novel treatment for low-energy electrons and photons

Hongwan Liu, Wenzer Qin, Gregory W. Ridgway +1

Decaying or annihilating dark matter and other exotic energy injections can modify the spectrum of the universe's photon bath, resulting in e.g. new contributions to spectral disto…

Planck Constraints and Gravitational Wave Forecasts for Primordial Black Hole Dark Matter Seeded by Multifield Inflation

Wenzer Qin, Sarah R. Geller, Shyam Balaji +2

We perform a Markov Chain Monte Carlo (MCMC) analysis of a simple yet generic multifield inflation model characterized by two scalar fields coupled to each other and nonminimally c…

Triply charmed baryons mass decomposition from lattice QCD

Jin-Bo Li, Long-Cheng Gui, Wei Sun +2

We present the first calculation of the connected scalar matrix element and the momentum fraction of charm quark within the $\frac{3}{2}^{+}$ and $\frac{3}{2}^{-}$ triply charmed bar…

Investigations on the charmless decays of $X (3872)$ in intermediate meson loops model

Yan Wang, Qi Wu, Gang Li +4

The charmless decay processes of $X (3872)$ provide us a good platform to study the nature and the decay mechanism of $X (3872)$ . Based on a molecular nature of $X (3872)$ as a $\bar{…

An Effective Bias Expansion for 21 cm Cosmology in Redshift Space

Wenzer Qin, Katelin Schutz, Aaron Smith +4

A near-future detection of the 21cm signal from the epoch of reionization will provide unique opportunities to probe the underlying cosmology, provided that such cosmological infor…

Primordial Black Holes from Multifield Inflation with Nonminimal Couplings

Sarah R. Geller, Wenzer Qin, Evan McDonough +1

Primordial black holes (PBHs) provide an exciting prospect for accounting for dark matter. In this paper, we consider inflationary models that incorporate realistic features from h…

Production of $Z_{cs}$ in $B$ and $B_{s}$ decay

Qi Wu, Dian-Yong Chen, Wen-Hua Qin +1

In the present work, we investigate the production of $Z_{cs}^{+}$ in $B^{+}$ and $B_{s}^{0}$ decay, where $Z_{cs}^{+}$ is assigned as a $D_{s}^{+} D ˉ^{* 0} + D_{s}^{*+} D ˉ^{0}$ mol…

Two and Three Pseudoscalar Production in $e^{+} e^{-}$ annihilation and their contributions to $(g - 2)_{μ}$

Wen Qin, Ling-Yun Dai, Jorge Portoles

A coherent study of $e^{+} e^{-}$ annihilation into two ( $π^{+} π^{-}$ , $K^{+} K^{-}$ ) and three ( $π^{+} π^{-} π^{0}, π^{+} π^{-} η$ ) pseudoscalar meson production is carried out within the…

Lyman- $α$ Constraints on Cosmic Heating from Dark Matter Annihilation and Decay

Hongwan Liu, Wenzer Qin, Gregory W. Ridgway +1

We derive new constraints on models of decaying and annihilating dark matter (DM) by requiring that the energy injected into the intergalactic medium (IGM) not overheat it at late…

Subluminal stochastic gravitational waves in pulsar-timing arrays and astrometry

Wenzer Qin, Kimberly K. Boddy, Marc Kamionkowski

The detection of a stochastic background of low-frequency gravitational waves by pulsar-timing and astrometric surveys will enable tests of gravitational theories beyond general re…

Pulsar-timing arrays, astrometry, and gravitational waves

Wenzer Qin, Kimberly K. Boddy, Marc Kamionkowski +1

We discuss the theory of pulsar-timing and astrometry probes of a stochastic gravitational-wave background with a recently developed "total-angular-momentum" (TAM) formalism for co…

The Mira-based distance to the Galactic centre

Wenzer Qin, David M. Nataf, Nadia Zakamska +2

Mira variables are useful distance indicators, due to their high luminosities and well-defined period-luminosity relation. We select 1863 Miras from SAAO and MACHO observations to…

Revisiting the pseudoscalar meson and glueball mixing and key issues in the search for pseudscalar glueball state

Wen Qin, Qiang Zhao, Xian-Hui Zhong

We revisit the mixing mechanism for pesudscalar mesons and glueball which is introduced by the axial vector anomaly. We demonstrate that the physical mass of the pseudoscalar glueb…
