For pure bosonic sector, we considered a heavy Higgs boson produced through VBF process and decaying through Zh(125) channel,...
708. A MeV-Scale Dark QCD Solution to the Axion Domain Wall Problem
康召丰
30/10/2026, 14:15

PQ solution to the strong CP problem probably encounters the axion domain wall problem. In this article, we propose a simple and testable solution, assuming that the U(1)PQU(1)PQ​ possesses mixed anomaly to a hidden SU(Nc)SU(Nc​) color. Then, the axion field receives a new cosine potential from the hidden instantons, which breaks the ZNDWZNDW​​ subgroup explicitly. The new potential lifts the...

"We perform the first complete $\mathcal{O}(\alpha_s^5)$ analysis of the prompt hadroproduction of $J/\psi$ pairs with large transverse momenta $p_T^{\psi\psi}$​ in the nonrelativistic-QCD factorization framework, including all possible Fock state combinations $c\bar{c}(m)+c\bar{c}(n)$, with $m,n=^3S_1^{[1,8]},^1S_0^{[8]},^3P_{J}^{[1,8]}$​. We observe that CMS and ATLAS data constrain a...
747. Quantum simulation of dijet production in a QCD medium
Meijian Li
30/10/2026, 14:15

"Dijet production in high-energy collisions encodes rich information about the surrounding QCD medium, yet computing these multi-particle processes requires non-perturbative input that remains challenging for conventional approaches.

713. Quantum Tomography of Top Quarks as a Probe of Charge-Parity Violation
谢可平
30/10/2026, 15:30

LHC measurements now reconstruct all fifteen parameters of the $t\bar{t}$ two-qubit spin density matrix, which amounts to a full quantum tomography of the pair. We show that this data constrains CP violation in the top-Yukawa coupling. The coupling enters the density matrix at one loop and produces spin correlations that are odd under CP and do not affect the cross section. Using the first...

739. Probing the Color-Octet Mechanism via Dihadron Fragmentation in $\chi_b$ Decays
文新锴
30/10/2026, 16:35

The color-octet (CO) mechanism is a cornerstone of nonrelativistic QCD, yet knowledge of its long-distance matrix elements remains limited, preventing stringent tests of the theory. We demonstrate that the Artru-Collins asymmetry in hadronic decays of the $P$-wave bottomonium state $\chi_{b2}$ provides a direct probe of CO dynamics. At leading order, the asymmetry arises exclusively from the...

金玉敬
30/10/2026, 16:35

We present a template fitting strategy for the VBF H→μμ search in ATLAS. Among all Higgs production modes, VBF is one of the most important for H→μμ, and its distinct di-jet signature significantly helps reduce background. For high S/B VBF categories, limited sideband statistics become a bottleneck for sensitivity, to address this, a Monte Carlo-based background estimation with a template fit...

Shu-Tao Zhang
30/10/2026, 16:50

Directly probing light-quark Yukawa couplings and their flavor structure remains a major challenge due to their smallness and overwhelming QCD backgrounds. In this Letter, we propose a theoretical framework to access these couplings at lepton colliders through transverse spin dependent azimuthal modulations in dihadron fragmentation. These modulations arise from the interference between Higgs...

都小康
30/10/2026, 17:35

We study a generalized NMSSM in which a gauge singlet connects the MSSM $\mu$ problem to neutrino masses from the type-II seesaw. Its vacuum expectation value contributes to $\mu_{\rm eff}$ and generates the supersymmetric mass of a vectorlike electroweak triplet pair. Integrating out the triplets yields the Weinberg operator, while their gauge charges admit a possible messenger...

Searches for low-mass dijet resonances at the LHC use hard initial-state radiation, either an isolated photon or a jet, to reach masses below the unprescaled trigger threshold. As the luminosity rises, more collisions are produced, so the unprescaled trigger has to raise its threshold to stay within the limited bandwidth and storage. Even with initial-state radiation, the low-mass region is...

Achieving a high-precision measurement of the Z boson mass using the dimuon final state requires an accurate calibration of the muon transverse momentum scale.

In this analysis, the calibration is perfomerd using the...
829. R&D on GAGG for the LHCb ECAL Upgrade II
Zhiyang Yuan
31/10/2026, 17:20

"The LHCb Upgrade II will operate at instantaneous luminosities up to 1.5×10³⁴ cm⁻²s⁻¹ and collect about 300 fb⁻¹ during the HL-LHC era. In the central region of the electromagnetic calorimeter this means MGy-level accumulated dose, more than 50 pile-up interactions per bunch crossing, and the need to keep an energy resolution of about 10%/√E ⊕ 1% while adding timing at the level of O(10 ps)....
794. Axion star bosenova in axion miniclusters
Zihang Wang
31/10/2026, 17:35

Axionic dark matter can form structures known as miniclusters that host an axion star at their center. The axion star feeds on the host, and the axion star mass may grow beyond its stability limit, leading to a potential bosenova. Since a dilute axion star has a stable mass limit only when self-interaction is considered, we include axion self-interaction effects in this paper, and specify the...

We propose a new class of dark-shower signatures in Standard Model extensions featuring Hidden Valleys or dark sectors coupled through an s-channel mediator. In this framework, unstable dark pions appear as long-lived particles (LLPs), with their lifetimes treated as free parameters. The resulting signatures, which we term semi-visible emerging jets (SVEJ), continuously interpolate between the...

Xiang Li
01/11/2026, 08:45

We propose an analyticity bootstrap method to determine the reduction of Feynman integrals (FIs). The key observation is that, at any kinematic point, a dimensionally regularized FI possesses a Taylor expansion region (analytic region), and the finiteness of the Taylor region strongly constrains the integral reduction coefficients, which are rational functions of the kinematic variables. By...
