Revisiting the $Λ (1405)$ pole structure with convolutional neural networks

Julius B. Pagayon, Vince Angelo A. Chavez, Denny Lane B. Sombillo

We revisit the long-standing ambiguity surrounding the complex pole structure of the $Λ (1405)$ resonance by reframing it as a classification problem for convolutional neural networ…

Line shape analysis of $I^ (1405)$ in $I^^{3} p \to K^{+} I^£^{-} I ¨ ^{+}$ reaction using convolutional neural network

Vince Angelo A. Chavez, Denny Lane B. Sombillo

Interpreting peaks or dips that appear in an invariant mass distribution is a recurring challenge in hadron physics. These enhancements can be ambiguous, especially near a two-hadr…

A Deep Learning Framework for Disentangling Triangle Singularity and Pole-Based Enhancements

Darwin Alexander O. Co, Vince Angelo A. Chavez, Denny Lane B. Sombillo

Enhancements in the invariant mass distribution or scattering cross-section are usually associated with resonances. However, the nature of exotic signals found near hadron-hadron t…

Pole structure of $P_{I ¨} ^{N} (4312)^{+}$ via machine learning and uniformized S-matrix

Leonarc Michelle Santos, Vince Angelo A. Chavez, Denny Lane B. Sombillo

We probed the pole structure of the $P_{I ¨} ^{N} (4312)^{+}$ using a trained deep neural network. The training dataset was generated using uniformized independent S-matrix poles to ens…
