A research group has measured an anomalous fractional charge carrier excitation in a novel bilayer graphene structure, which deviates from existing theoretical predictions. For this high-impact claim to be validated and accepted as established scientific knowledge by the physics community, which of the following procedures is essential?
Announce the discovery via a national press release and social media platforms to generate public consensus, which serves as the primary validation of the experimental data.
Submit a detailed manuscript to a peer-reviewed journal for evaluation by independent experts, enabling other research groups to scrutinize and replicate the experiment.
Keep the calibration parameters and specific sample preparation techniques confidential to protect intellectual property while publishing only the final observational curves.
Present the results at an internal departmental seminar and immediately update international physics textbooks and databases without external verification.
