Ionization Potential Depression and Fermi Barrier in Warm Dense Matter: A First‐Principles Approach
Contributions to Plasma Physics, EarlyView.ABSTRACT Ionization potential depression (IPD) is of crucial importance to understand and accurately predict the properties of dense, partially ionized plasmas. Many models of IPD have been developed that, however, exhibit largely varying results. Recently, a novel approach was proposed that is based on first‐principles quantum Monte Carlo simulations ...

Gauge Boson Mass Dependence and Chiral Anomalies in Generalized Massless Schwinger models [PDF]
arXiv, 2023 I bosonize the position-space correlators of flavor-diagonal scalar fermion bilinears in arbitrary generalizations of the Schwinger model with $n_F$ massless fermions coupled to $n_A$ gauge bosons for $n_F\geq n_A$. For $n_A=n_F$, the fermion bilinears can be bosonized in terms of $n_F$ scalars with masses proportional to the gauge couplings. As in the

Journal of High Energy Physics, 2018 We construct a self-interacting dark matter model that could simultaneously explain the observed muon anomalous magnetic moment. It is based on a gauged U1Lμ−Lτ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ extension of the standard model, where we ...

Higgs-gauge boson interactions in the economical 3-3-1 model
, 2006 Interactions among the standard model gauge bosons and scalar fields in the framework of SU(3)_C X SU(3)_L X U(1)_X gauge model with minimal (economical) Higgs content are presented. From these couplings, all scalar fields including the neutral scalar $h$

Electroweak gauge boson polarisation at the LHC [PDF]
, 2012 A bstractWe study the polarisation of gauge bosons produced at the LHC. Polarisation effects for W bosons manifest themselves in the angular distributions of the lepton and in the distributions of lepton transverse momentum and missing transverse energy.

Non‐Markovian Quantum Kinetic Simulations of Uniform Dense Plasmas: Mitigating the Aliasing Problem
Contributions to Plasma Physics, EarlyView.ABSTRACT Dense quantum plasmas out of equilibrium are successfully modeled using quantum kinetic equations, such as the quantum Boltzmann, Landau, or Balescu–Lenard equation. However, these equations do not properly take into account correlation effects, which require the use of generalized non‐Markovian kinetic equations.

Helicity amplitudes without gauge cancellation for electroweak processes
European Physical Journal C: Particles and Fields, 2023 In the 5-component representation of weak bosons, the first four components make a Lorentz four vector, representing the transverse and longitudinal polarizations excluding the scalar component of the weak bosons, whereas its fifth component corresponds ...

Low‐Frequency Raman Spectroscopy of Polymers
Macromolecular Chemistry and Physics, EarlyView.Recent advances have made low‐frequency Raman spectroscopy accessible to the wider scientific community. This review discusses how low‐frequency Raman is particularly useful for researchers investigating polymers because the technique can help determine both the local and long‐range structure of materials, their thermodynamic properties, and their ...

Measurement of gauge boson couplings and W spin density matrix [PDF]
arXiv, 2003 During the LEP2 period the e+e- collider increased its center of mass energy from 161 GeV to 209 GeV and a total integrated luminosity of approximately 700 pb-1 was recorded per experiment. Pairs of W bosons are produced and allow the study of gauge boson couplings involving W, Z and photon.

Gauge Boson Mixing in the 3-3-1 Models with Discrete Symmetries
Advances in High Energy Physics, 2012 The mixing among gauge bosons in the 3-3-1 models with the discrete symmetries is investigated. To get tribimaximal neutrino mixing, we have to introduce sextets containing neutral scalar components with lepton number L=1,2.
