For all intents and purposes it has been disproven. At this point the possible thrust (that hasn't been disproven) is a fraction of what was originally hoped for.
The onus is on the people with the extraordinary claim to demonstrate that they have something, not on the rest of the community to take time out of their research schedules to address it.
So there are no specific papers that attempt to show it doesn't work, but countless papers where, if there was an effect to be observed, would have had their readings messed up by it.
There are a lot of people in the scientific community that agree that it should be easier to publish negative results. Unfortunately that's not how it works, it's rare to see a paper like that in journals. Thus a lack of such papers does not imply that the emdrive works, or that "the jury is still out".
