Tensor Amplitudes for Partial Wave Analysis of $\mathit{\psi }\mathbf{\to }\mathbf{\Delta }\overline{\mathbf{\Delta }}$ within Helicity Frame

Universe
We have derived the tensor amplitudes for partial wave analysis of ψ→ΔΔ¯, Δ→pπ within the helicity frame, as well as the amplitudes for the other decay sequences with same final states.

Chiral Baryon Fields in the QCD Sum Rule

, 2012
We study the structure of local baryon fields using the method of QCD sum rule. We only consider the single baryon fields and calculate their operator product expansions. We find that the octet baryon fields belonging to the chiral representations [(3,3*)

Critical assessment of CMB limits on dark matter-baryon scattering: New treatment of the relative bulk velocity [PDF]

Physical Review D, 2018
We perform an improved cosmic microwave background (CMB) analysis to search for dark matter-proton scattering with a momentum-transfer cross section of the form $\sigma_0 v^n$ for $n=-2$ and $n=-4$. In particular, we present a new and robust prescription

Baryon and Lepton Number Assignment in $E_6$ Models [PDF]

, 1995
In $E_6$ models there are new particles whose baryon number is not uniquely assigned. We point out that the baryon and lepton number assignment to these particles can change the baryogenesis scenario significantly.

Elucidating ΛCDM: Impact of Baryon Acoustic Oscillation Measurements on the Hubble Constant Discrepancy [PDF]

, 2017
We examine the impact of baryon acoustic oscillation (BAO) scale measurements on the discrepancy between the value of the Hubble constant (H0) inferred from the local distance ladder and that from Planck cosmic microwave background (CMB) data.

First Observation of the Doubly Charmed Baryon Decay Ξ_{cc}^{++}→Ξ_{c}^{+}π^{+}. [PDF]

Physical Review Letters, 2018
The doubly charmed baryon decay Ξ_{cc}^{++}→Ξ_{c}^{+}π^{+} is observed for the first time, with a statistical significance of 5.9σ, confirming a recent observation of the baryon in the Λ_{c}^{+}K^{-}π^{+}π^{+} final state.

Baryon-baryon interactions in free space and baryonic medium

, 2003
We study the interactions of the octet baryons in a relativistic meson exchange approach connecting free-space and in-medium interactions with those in finite (hyper)nuclei. A short sketch of the model including the relativistic T- and G-matrix and the mapping of the G-matrix onto density dependent vertex functionals in the density dependent ...

QCD and e+e- --> Baryon + anti-Baryon [PDF]

, 2002
We discuss the QCD constraints on e+e- --> baryon-anti-baryon close to threshold, in light of the puzzling experimental data which indicate that close to threshold sigma (e+e- --> n n-bar) > sigma (e+e- --> p p-bar).

Baryon-baryon interactions from Effective Field Theory

EPJ Web of Conferences, 2010
I report on recent progress in the description of baryon-baryon systems within chiral effective field theory. In particular, results for the hyperon-nucleon and hyperon-hyperon interactions as well as for strangeness S = −3 to −4 baryon-baryon systems ...
