A Unified Dark-Matter--Driven Relativistic Bondi Route to Black-Hole Growth from Stellar to Supermassive Scales
Chian-Shu Chen, Feng-Li Lin
Observations of luminous quasars at reveal supermassive black holes (SMBHs) with inferred masses formed within the first ~Myr o…
Interpretation of LHC excesses at 95 GeV and 152 GeV in an extended Georgi-Machacek model
Ting-Kuo Chen, Cheng-Wei Chiang, Sven Heinemeyer +1
We analyze the excesses at 95 GeV in the light Higgs-boson searches in the di-photon decay channel reported by CMS and ATLAS, which combined are at the level of three standard devi…
Probing the Axion-Photon-Dark Photon Interaction at Future Colliders
Chuan-Ren Chen, Yuan-Feng Hsieh, Van Que Tran
We study the interaction between photons, dark photons, and axions at future lepton colliders, focusing on single-photon events with missing energy as the experimental signature. W…
Doubly charged Higgs boson at same-sign lepton colliders
Cheng-Wei Chiang, Kazuki Enomoto, Min-Yuan Liao
We investigate the search for doubly charged Higgs bosons in the Georgi-Machacek (GM) model at same-sign lepton colliders. The dominant production mode is vector boson fusion, thro…
Mapping the evolution of supernova-neutrino-boosted dark matter within the Milky Way
Yen-Hsun Lin, Meng-Ru Wu
Supernova-neutrino-boosted dark matter (SN BDM) has emerged as a promising portal for probing sub-GeV dark matter. In this work, we investigate the behavior of BDM signatures or…
Constraining neutrino charges at beam experiments
Jack D. Shergold, Martin Spinrath
We propose a new method to constrain neutrino charges at neutrino beam experiments. Uncharged in the Standard Model, evidence for a neutrino electric charge would be a smoking gun…
A 95 GeV Higgs Boson in the Georgi-Machacek Model
Ting-Kuo Chen, Cheng-Wei Chiang, Sven Heinemeyer +1
CMS and ATLAS have reported small excesses in the search for low-mass Higgs bosons in the di-photon decay channel at exactly the same mass, GeV. These searches rely on impro…
Signatures of afterglows from light dark matter boosted by supernova neutrinos in current and future large underground detectors
Yen-Hsun Lin, Tsung-Han Tsai, Guey-Lin Lin +2
Supernova neutrino boosted dark matter (SN BDM) and its afterglow effect have been shown to be a promising signature for beyond Standard Model (bSM) physics. The time-evolution…
Phenomenological study of a gauged model with a scalar leptoquark
Chuan-Hung Chen, Cheng-Wei Chiang, Chun-Wei Su
A gauge boson with sub-GeV mass has acquired a significant interest in phenomenology, particularly in view of the muon anomaly and coherent elastic neutrino-nucleon scat…
Observability of the Higgs boson decay to a photon and a dark photon
Hugues Beauchesne, Cheng-Wei Chiang
Many collider searches have attempted to detect the Higgs boson decaying to a photon and an invisible massless dark photon. For the branching ratio to this channel to be realistica…
Symmetry and bipolar motion in collective neutrino flavor oscillations
Zewei Xiong, Meng-Ru Wu, Yong-Zhong Qian
We identify a geometric symmetry on the two-flavor Bloch sphere for collective flavor oscillations of a homogeneous dense neutrino gas. Based on this symmetry, analytical solutions…
Uncovering tau leptons-enriched semi-visible jets at the LHC
Hugues Beauchesne, Cesare Cazzaniga, Annapaola de Cosa +4
This Letter proposes a new signature for confining dark sectors at the Large Hadron Collider. Under the assumption of a QCD-like hidden sector, hadronic jets containing stable dark…
Collisional flavor instability in dense neutrino gases
Zewei Xiong, Lucas Johns, Meng-Ru Wu +1
Charged-current neutrino processes such as and destroy the flavor coherence among the weak-interaction…
Bremsstrahlung from Neutrino Scattering via Magnetic Dipole Moments
Konstantin Asteriadis, Alejandro Quiroga Triviño, Martin Spinrath
In this paper we discuss bremsstrahlung induced by neutrino scattering. This process should exist since neutrinos are expected to couple to photons via magnetic dipole and transiti…
Searching for Afterglow: Light Dark Matter Boosted by Supernova Neutrinos
Yen-Hsun Lin, Wen-Hua Wu, Meng-Ru Wu +1
A novel analysis is performed, incorporating time-of-flight (TOF) information to study the interactions of dark matter (DM) with standard model particles. After supernova (SN) expl…
Is the decay of the Higgs boson to a photon and a dark photon currently observable at the LHC?
Hugues Beauchesne, Cheng-Wei Chiang
Many attempts have been made to observe the decay of the Higgs boson to a photon and an invisible massless dark photon. For this decay to be potentially observable at the LHC, new…
Probing WIMPs in space-based gravitational wave experiments
Bo-Qiang Lu, Cheng-Wei Chiang, Da Huang
Although searches for dark matter have lasted for decades, no convincing signal has been found without ambiguity in underground detections, cosmic ray observations, and collider ex…
Updated constraints on Georgi-Machacek model, and its electroweak phase transition and associated gravitational waves
Ting-Kuo Chen, Cheng-Wei Chiang, Cheng-Tse Huang +1
With theoretical constraints such as perturbative unitarity and vacuum stability conditions and updated experimental data of Higgs measurements and direct searches for exotic scala…
Scotogenic top-quark FCNC decays
Chuan-Hung Chen, Takaaki Nomura
Flavor-changing neutral current (FCNC) top-quark decays are highly suppressed due to the Glashow-Iliopoulos-Maiani mechanism in the standard model (SM). If with $V=g…
Two- and three-body hadronic decays of charmed mesons involving a tensor meson
Hai-Yang Cheng, Cheng-Wei Chiang, Zhi-Qing Zhang
We study the quasi-two-body decays and the three-body decays proceeding through intermediate tensor resonances, where and denote tensor and pseudoscalar meson…
Theory, phenomenology, and experimental avenues for dark showers: a Snowmass 2021 report
Guillaume Albouy, Jared Barron, Hugues Beauchesne +51
In this work, we consider the case of a strongly coupled dark/hidden sector, which extends the Standard Model (SM) by adding an additional non-Abelian gauge group. These extensions…
Gravitational waves in models with multicritical-point principle
Yuta Hamada, Hikaru Kawai, Kiyoharu Kawana +2
The multicritical-point principle (MPP) provides a natural explanation of the large hierarchy between the Planck and electroweak scales. We consider a scenario in which MPP is appl…
