Abstract:

We prove that Langlands-Shahidi $L$-functions in the case of $GSpin$ groups over a non-Archimedean local field of characteristic zero are Artin $L$-functions through the local Langlands correspondence. This has an application in the proof of a weak version of the generic Arthur packet conjecture. Furthermore, we study and describe a local $L$-packet that contains a generic member in the case of $GSpin$ groups. Using this description of a local $L$-packet, we strengthen a weak version of the generic Arthur packet conjecture in the case of $GSpin$ groups (i.e. a local version of the generalized Ramanujan conjecture).
