Noncanonical cosmology with an uplifted Higgs vacuum expectation value (Higgs-VEV) in the early universe is believed to provide solution for existing tensions within $\mathrm{\ensuremath{\Lambda}}$-cold-dark-matter ($\mathrm{\ensuremath{\Lambda}}\mathrm{CDM}$) regime. We recently proposed a theoretical model called axion-Higgs explore this framework. The features ultralight axion mass ${m}_{a}\...

We study the unitarized meson-baryon scattering amplitude at leading order in strangeness $S=-1$ sector using time-ordered perturbation theory for a manifestly Lorentz-invariant formulation of chiral effective field theory. By solving coupled-channel integral equations with full off-shell dependence potential and applying subtractive renormalization, we analyze renormalized amplitudes obtain tw...

We calculate the form factors of ${\mathrm{\ensuremath{\Lambda}}}_{b}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Lambda}}}_{c}(2625)$ and ${\mathrm{\ensuremath{\Xi}}}_{b}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Xi}}}_{c}(2815)$ transitions, additionally evaluate corresponding semileptonic decays color-allowed two-body nonleptonic decays. In order to obtain concerned factors, we use three...

One of the most prominent challenges to standard Lambda cold dark matter ($\Lambda$CDM) cosmology is tension between structure growth parameter $S_8$ constrained by cosmic microwave background (CMB) data and smaller one suggested shear data. Recent studies show that, for $\Lambda$CDM cosmology, redshift-space distortion (RSD) also prefers a that $\sim 2$-$3\sigma$ lower than CMB value, but resu...

The magnetic moments of Λ-hypernuclei are the most interesting observables which provide a highly sensitive probe lambda in hypernuclei structure and also supply direct information on hyperon-nucleon interactions. In this work, we derive such as O , C Ca employing relativistic approach presence Dirac equation spin-orbital potential their ground excited states, i.e. 1S1/2, 1P3/2 1P1/2 states. We...

We investigate the in-medium properties of hyperons and anti-hyperons in framework Non-Linear Derivative (NLD) model. focus on momentum dependence strangeness optical potentials. The NLD model is based simplicity well-established Relativistic Mean-Field (RMF) approximation, but it incorporates an explicit a field-theoretical level. extension to (anti)baryon-octet formulated spirit SU(6) G-parit...

We propose a new application of lattice QCD to calculate the quark-diquark potential, diquark mass, and quark mass required for model. As concrete example, we consider ${\mathrm{\ensuremath{\Lambda}}}_{c}$ baryon treat it as charm-diquark ($c$-[$ud$]) two-body bound state. extend HAL method which reproduces equal-time Nambu-Bethe-Salpeter wave function S-wave state [${\mathrm{\ensuremath{\Lambd...

Annihilation dynamics plays a fundamental role in the baryon$-$antibaryon interaction (B$-\rm{\overline{B}}$) at low-energy and its strength range are crucial assessment of possible baryonic bound states. Experimental data on annihilation cross sections available for p$-\rm{\overline{p}}$ system but not low relative momentum region. Data regarding B$-\rm{\overline{B}}$ with strange degrees free...

We perform the first test of dark matter (DM) stress-energy evolution through cosmic history, using microwave background measurements supplemented with baryon acoustic oscillation data and Hubble Space Telescope key project data. constrain DM equation state (EoS) in 8 redshift bins, its sound speed (shear) viscosity 9 finding no convincing evidence for non-$\Lambda$CDM values any bins.
