Search for an exotic decay of the Higgs boson to a pair of light pseudoscalars in the final state with two b quarks and two τ leptons in proton–proton collisions at s=13TeV

open access: yesPhysics Letters B, 2018
A search for an exotic decay of the Higgs boson to a pair of light pseudoscalar bosons is performed for the first time in the final state with two b quarks and two τ leptons. The search is motivated in the context of models of physics beyond the standard

Long DNA molecule as a pseudoscalar liquid crystal [PDF]

open access: yesarXiv, 2009
We show that a long DNA molecule can form a novel condensed phase of matter, the pseudoscalar liquid crystal, that consists of aperiodically ordered DNA fragments in right-handed B and left-handed Z forms. We discuss the possibility of transformation of B-DNA into Z-DNA and vice versa via first-order phase transitions as well as transformations from ...

Is there a scalar or pseudoscalar at 95 GeV?

open access: yesPhysical Review D
We discuss the possibility of interpreting the recent experimental hints in favor of a 95 GeV resonance with extensions of the Standard Model featuring an extra Higgs doublet and SM scalar (2HDM+s) or pseudoscalar singlet (2HDM+a). We compare the possibility of reproducing the experimental anomalies with the theoretical constraints on the extended ...

Excited vector mesons: phenomenology and predictions for a yet unknown vector ss state with a mass of about 1.93 GeV

open access: yesEPJ Web of Conferences, 2018
The firm understanding of standard quark-antiquark states (including excited states) is necessary to search for non-conventional mesons with the same quantum numbers.

Interaction of the pseudoscalar glueball with (pseudo)scalar mesons and nucleons [PDF]

open access: yesarXiv, 2012
We study the interactions of the pseudoscalar glueball with scalar and pseudoscalar quark-antiquark meson fields and with the nucleon and its chiral partner. In both cases we introduce the corresponding chiral Lagrangian and discuss its properties. We calculate the mesonic and baryonic decays of a pseudoscalar glueball with mass of about 2.6 GeV as ...
