A search for a pseudoscalar a produced in association with a top-quark pair, or in association with a single top quark plus a W boson, with the pseudoscalar decaying into b-quarks ( $$a\rightarrow b\bar{b}$$ a → b b ¯ ), is performed using the full Run 2

Properties of flavour-singlet pseudoscalar mesons from lattice QCD
We report on the status of the determination of properties of flavour-singlet pseudoscalar mesons using Wilson twisted mass lattice QCD at maximal twist.

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

Minimal renormalizable simplified dark matter model with a pseudoscalar mediator [PDF]
We consider a minimal renormalizable and gauge invariant dark matter (DM) model, in which the singlet fermion DM has only axial couplings to a new pseudoscalar mediator. The mixing between the pseudoscalar mediator and the standard model (SM) Higgs boson

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.

Type-III two Higgs doublet model plus a pseudoscalar confronted with h→μτ, muon g−2 and dark matter
In this work, we introduce an extra singlet pseudoscalar into the Type-III two Higgs doublet model (2HDM) which is supposed to solve a series of problems in the modern particle-cosmology.

Nπ states and the projection method for the nucleon axial and pseudoscalar form factors
The RQCD collaboration proposed a projection method to remove the excited state contamination in lattice OCD calculations of nuclear form factors. The effectiveness of this method in removing the two-particle nucleon-pion-state contamination is examined ...

New exclusion limits on scalar and pseudoscalar axionlike particles from light shining through a wall [PDF]
Physics beyond the Standard Model predicts the possible existence of new particles that can be searched at the low-energy frontier in the sub-eV range. The OSQAR photon regeneration experiment looks for ``light shining through a wall'' from the quantum ...
