Optimal Learning Rate Schedules under Functional Scaling Laws: Power Decay and Warmup-Stable-Decay
Binghui Li, Zilin Wang, Fengling Chen +3
We study optimal learning rate (LR) schedules under the functional scaling law (FSL) framework (Li et al., 2025), which decomposes training dynamics into signal learning and noise…
Coscattering/Coannihilation Dark Matter in a Fraternal Twin Higgs Model
Hsin-Chia Cheng, Lingfeng Li, Rui Zheng
Dark matter candidates arise naturally in many models that address the hierarchy problem. In the fraternal twin Higgs model which could explain the absence of the new physics signa…
Lepton-portal Dark Matter in Hidden Valley model and the DAMPE recent results
Yi-Lei Tang, Lei Wu, Mengchao Zhang +1
We study the recent cosmic ray excess reported by DAMPE in a Hidden Valley Model with lepton-portal dark matter. We find the electron-portal can account for the excess well…
Simplified TeV leptophilic dark matter in light of DAMPE data
Guang Hua Duan, Lei Feng, Fei Wang +3
Using a simplified framework, we attempt to explain the recent DAMPE cosmic flux excess by leptophilic Dirac fermion dark matter (LDM). The scalar () and vector ($…
Electroweak-Charged Bound States as LHC Probes of Hidden Forces
Lingfeng Li, Ennio Salvioni, Yuhsin Tsai +1
We explore the LHC reach on beyond-the-Standard Model (BSM) particles associated with a new strong force in a hidden sector. We focus on the motivated scenario where the SM and…
Resonant Higgs pair production as a probe of stop at the LHC
Guang Hua Duan, Lei Wu, Rui Zheng
Searching for top squark (stop) is a crucial task of the LHC. When the flavor conserving two body decays of the stop are kinematically forbidden, the stops produced near the thresh…
Phenomenology of Bulk Scalar Singlets in the Randall Sundrum Model
Fayez Abu-Ajamieh, Rachel Houtz, Rui Zheng
We present a Randall-Sundrum toy model with an added scalar singlet that couples only to KK fermions in the bulk. Such a scalar would nontrivially affect radion phenomenology. In a…
Boosted scalar confronting 750 GeV di-photon excess
Yun Jiang, Lingfeng Li, Rui Zheng
We consider the di-photon signal arises from two bunches of collimated photon jets emitting from a pair of highly boosted scalars. Following the discussion of detecting the photon…
750 GeV Diphoton Resonance in a Vector-like Extension of Hill Model
Ning Liu, Wenyu Wang, Mengchao Zhang +1
In this paper, we study the recent 750 GeV diphoton excess in the Hill Model with vector-like fermions, in which the singlet-like Higgs boson is chosen as 750 GeV resonance and is…
Metamaterials Mimicking Dynamic Spacetime, D-brane and Noncommutativity in String Theory
Rong-Xin Miao, Rui Zheng, Miao Li
We propose an executable scheme to mimic the expanding cosmos in 1+2 dimensions in laboratory. Furthermore, we develop a general procedure to use nonlinear metamaterials to mimic D…
