A heavy neutral gauge boson near the Z boson mass pole via third generation fermions at the LHC
Physics Letters B, 2020 We explore the physics of a new neutral gauge boson, (Z′), coupling to only third-generation particles and with a mass near the electroweak gauge boson mass poles. A Z′ boson produced by top quarks and decaying to tau leptons is considered. With a simple

Singlet fermionic dark matter with dark Z
European Physical Journal C: Particles and Fields, 2020 We present a fermionic dark matter model mediated by the hidden gauge boson. We assume the QED-like hidden sector which consists of a Dirac fermion and U(1)$$_X$$ X gauge symmetry, and introduce an additional scalar electroweak doublet field with the U(1)

Active Learning in Physics: From 101, to Progress, and Perspective
Advanced Quantum Technologies, EarlyView., 2023 In this review, the concept of active learning is introduced to the physicists at the level of beginner without requirement on background in machine learning. It includes most of the latest applications of active learning in branches of physics, covering but not being limited to quantum information, high energy physics, and condensed matter physics. It

Benefits of Open Quantum Systems for Quantum Machine Learning
Advanced Quantum Technologies, EarlyView., 2023 Quantum machine learning (QML), poised to transform data processing, faces challenges from environmental noise and dissipation. While traditional efforts seek to combat these hindrances, this perspective proposes harnessing them for potential advantages. Surprisingly, under certain conditions, noise and dissipation can benefit QML.

Vector gauge boson radiation from compact binary systems in a gauged Lμ−Lτ scenario [PDF]
Physical Review D, 2019 The orbital period of the binary neutron star systems decrease due to mainly quadrupole gravitational radiation which agrees with the observation to within one percent. Other types of radiation such as ultralight scalar or pseudoscalar radiation, massive

Preheating after Higgs inflation: Self-resonance and gauge boson production [PDF]
Physical Review D, 2018 We perform an extensive analysis of linear fluctuations during preheating in Higgs inflation in the Einstein frame, where the fields are minimally coupled to gravity, but the field-space metric is nontrivial.

Anomalous triple-gauge-boson interactions in vector-boson pair production with Recola2 [PDF]
The European Physical Journal C, 2018 Diboson production at the LHC is a process of great importance both in the context of tests of the SM and for direct searches for new physics. In this paper we present a phenomenological study of $$\mathrm {W}\mathrm {W}$$WW ($$\rightarrow \mathrm {e ...
