What is the fundamental reason of the fermion doubling?
1 Answer
Saurabh Koranglekar
Dear student
The reason for the fermion doubling lies in the existence of chiral anomaly. This anomaly exists in the continuum limit due to the chiral non-invariance of the path integral measure and not because of the non-invariance of Lagrangian.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
