Can the 126 GeV boson be a pseudoscalar?

open access: yes, 2012
We test the possibility that the newly-discovered 126 GeV boson is a pseudoscalar by examining the correlations among the loop-induced pseudoscalar decay branching fractions to $\gamma\gamma$, $ZZ^*$, $Z\gamma$, and $WW^*$ final states in a model ...

Discovering the Higgs with Low Mass Muon Pairs [PDF]

open access: yes, 2009
Many models of electroweak symmetry breaking have an additional light pseudoscalar. If the Higgs boson can decay to a new pseudoscalar, LEP searches for the Higgs can be significantly altered and the Higgs can be as light as 86 GeV. Discovering the Higgs

Decay of charmonium states into a scalar and a pseudoscalar glueball

open access: yesEPJ Web of Conferences, 2016
In the framework of a chiral symmetric model, we expand a U(4)R × U(4)L symmetric linear sigma model with (axial-)vector mesons by including a dilaton field, a scalar glueball, and the pseudoscalar glueball.

Heavy quark masses [PDF]

open access: yes, 1991
In the large quark mass limit, an argument which identifies the mass of the heavy-light pseudoscalar or scalar bound state with the renormalized mass of the heavy quark is given.

Exact formula of the spectrum of the pseudoscalar octet

open access: yesPhysics Letters B, 2015
Non-perturbative proof is presented of a generalized version of Goldstone theorem, where the Lagrangian conserves an approximate SU(3) chiral symmetry, that both quark masses and electromagnetism make contributions to the masses of spinless particles of ...

The $$\pi f_0(500)$$ π f 0 ( 500 ) decay of the $$a_1(1260)$$ a 1 ( 1260 )

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We evaluate the $$a_1(1260) \rightarrow \pi \sigma (f_0(500))$$ a 1 ( 1260 ) → π σ ( f 0 ( 500 ) ) decay width from the perspective that the $$a_1(1260)$$ a 1 ( 1260 ) resonance is dynamically generated from the pseudoscalar–vector interaction and the $$\

Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect

open access: yesAdvanced Physics Research, Volume 4, Issue 7, July 2025.
This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

Radiative Decay Widths of Ground and Excited States of Vector Charmonium and Bottomonium

open access: yesAdvances in High Energy Physics, 2017
We study the radiative decay widths of vector quarkonia for the process of J/ψ(nS)→ηc(nS)γ and Υ(nS)→ηb(nS)γ (for principal quantum numbers n=1,2,3) in the framework of Bethe-Salpeter equation under the covariant instantaneous ansatz using a 4×4 form of ...

Charming Higgs [PDF]

open access: yes, 2009
We present a simple supersymmetric model where the dominant decay mode of the lightest Higgs boson is h->2eta->4c where eta is a light pseudoscalar and c is the charm quark. For such decays the Higgs mass can be smaller than 100 GeV without conflict with

Notes on Parameterized Energy Pathways in the Ocean: Insights From Stochastic and Deterministic Kinetic Energy Injection

open access: yesJournal of Advances in Modeling Earth Systems, Volume 17, Issue 5, May 2025.
Abstract Accurately representing ocean dynamics across interacting scales remains a challenge in numerical modeling. This study examines mesoscale eddy parameterization in eddy‐permitting ocean models by incorporating novel stochastic perturbations and comparing them with a well‐tested dynamic kinetic energy backscatter scheme.
