We present the first lattice QCD determination of the Λ → N vector and axial-vector form factors, which are essential inputs for studying the semileptonic decay $\Lambda\rightarrow p \ell \overline{\nu}_\ell$. This channel provides a clean, theoretically controlled avenue for extracting the CKM matrix element |$V_{us}$| from the baryon sector. Our analysis uses a gauge ensemble with physical...

With the large datasets from $e^+e^-$ annihilation at the $J/\psi$ resonance collected at the BESIII experiment, multi-dimensional analyses leveraging polarization and entanglement can provide new insights into the hadronic structure of semileptonic decays. New studies at BESIII allow one to measure the form factor ratios of the (anti)hyperons in the decays $J/\psi\to\Lambda\bar{\Lambda}$ and...

Semileptonic hyperon decays provide a powerful and largely unexplored laboratory to test the Standard Model in the strange sector. In particular, they offer complementary sensitivity to lepton flavour universality (LFU) and to the CKM matrix element |$V_{us}$|, with different hadronic and operator sensitivities from the kaon sector. While the electron modes are known with relatively good...

It is discussed why decays of the Omega baryon can be an interesting test bed for the interplay of high-statistics experiments, lattice QCD, effective field theory and other QCD based methods. In particular, the semileptonic decays of the Omega baryon are related by flavor symmetry and crossing to the production of Delta baryons in neutrino-matter interactions [1,2] and to the Delta-Delta-pion...

In this talk, I review recent lattice-QCD results on meson-baryon spectroscopy. In particular, I present new results from the Baryon Scattering Collaboration for the $\Delta(1232)$ and $\Lambda(1405)$, obtained on an ensemble with $M_\pi \simeq 200$ MeV. For the $\Lambda(1405)$ channel, we find evidence for a two-pole structure. I also present a Bayesian analysis of the $\Lambda(1405)$ system...

resonance transition form factors. Our long-term aim is to apply the Lellouch-L\"uscher
formalism to extract infinite-volume $N\to N\pi$ form factors from finite-volume

We present recent results of the Baryon Scattering (BaSc) collaboration concerning two-baryon spectroscopy from Lattice QCD on CLS ensembles. We focus on two systems: nucleon-nucleon scattering in both isospin states, $I = 0$ (deuteron) and $I = 1$ (dineutron); and strangeness $S = -2$ hyperon-hyperon scattering in the H-dibaryon channel. The latter is a coupled-channel system of...

An enormous number of strange baryons, historically termed hyperons, are produced at the LHC. The lifetimes of ground state hyperons are two orders of magnitude larger than those of beauty and charm hadrons, which the LHCb detector was specifically built to reconstruct. I will highlight advantages and limitations in the reconstruction of hyperons at LHCb, and showcase the physics prospects of...

Nonleptonic hyperon transitions are studied in a relativistic framework of chiral perturbation theory ($\chi$PT). Previously, one-loop corrections to parity-violating and -conserving partial-wave amplitudes S and P have been computed in a nonrelativistic approach, focusing on the leading chiral logarithms [1]. This study concluded that a satisfying agreement with data and reasonable...

Perspectives for measurements of semileptonic and electromagnetic (Dalitz) decays of hyperons in proton-proton collisions at FAIR with the CBM detector will be given. The main motivation for these measurements is extraction of transition form-factors of the octet and decouplet ground states and improvements in precision of branching ratio determination. Combination of these two measurements...

The magnetic and electric dipole moments (MDM and EDM) of charm baryons have yet to be measured. These fundamental properties are sensitive probes of non-perturbative QCD dynamics and potential signatures of physics beyond the Standard Model. LHCb’s upgraded trigger presents new opportunities for physics analysis in charmed baryon decays. This report presents a pre-study of the promising...

In this talk I will give an overview of the phenomenology of neutron beta decays and the associated Standard Model precision tests in terms of the neutron axial charge $g_A$ and light-quark CKM element $V_{ud}$. Increased precision in current and planned experiments calls for improved theoretical predictions carefully taking into account the non-perturbative effects from QCD. With a precision...
