Classical Hardware Acceleration of Quantum Autoencoders for Real-Time Anomaly Detection in Collider Experiments

This paper presents the first FPGA implementation of variational quantum autoencoders for real-time anomaly detection in collider experiments, demonstrating that these quantum machine learning models can achieve performance comparable to state-of-the-art classical approaches while meeting the strict resource and latency constraints required for future trigger systems.

Nucleon unpolarized second Mellin moments using lattice QCD ensembles with physical quark masses and in the continuum limit

This paper presents a lattice QCD calculation of nucleon unpolarized second Mellin moments using four physical-mass ensembles to determine the continuum-limit contributions of quarks and gluons to the proton's momentum, angular momentum, and orbital angular momentum.

Decays of Standard Model like Higgs boson h→γγ,Zγh \rightarrowγγ, Z γ in a minimal left-right symmetric model

This paper investigates the one-loop decay channels of a Standard Model-like Higgs boson into ZγZ\gamma and γγ\gamma\gamma within a minimal left-right symmetric model, demonstrating that while current constraints on the γγ\gamma\gamma channel strictly limit the ZγZ\gamma signal strength, future experimental sensitivities could still allow significant deviations in the ZγZ\gamma decay that remain undetected by γγ\gamma\gamma measurements.

Gravitational Waves from Dark Gauge Sectors

This paper investigates gravitational wave signatures from strong first-order phase transitions in non-Abelian dark sectors that generate vector dark matter, demonstrating that models with fermionic or Higgs portals can produce detectable signals at LISA and future interferometers while simultaneously explaining dark matter abundance and offering a unique six-top collider signature at the HL-LHC.
