SuperFGD_PID

1.

Improving SuperFGD PID
Transformer-based particle identification
TRACK INFORMATION → PID
Node-level features
Track-level features
Transformer block
Dense layers
Feature fusion → PID (e / μ / π / p)
SuperFGD: a highly segmented scintillator detector
+12.86 pp | Pion PID efficiency gain
Current: PGUN → Next: NEUT MC

2.

Investigating the Origin of the PID Efficiency Gain
COMPARE → LOCALIZE → IDENTIFY → TEST
COMPARE | BDT vs Transformer NN
BDT
IDENTIFY | Integrated Gradients
LOCALIZE | Gain across track features
NN
TEST | Energy-profile intervention
PGUN: +12.86 pp pion efficiency (NN vs BDT) → NEXT: fixed-model evaluation on NEUT MC
