TL;DR: References [1-3] further below are the direct answer to your question, "What are the actual papers?" (the "3 papers" referenced in the submission title; those that it is said that Tessier-Lavigne will retract). The PubMed links are as follows:
From [0], "...To date, all three of these papers (Cell ’99, Science ’01 Binding, Science ’01 Silencing) remain published....Dr. Tessier-Lavigne has stated to the Panel that he intends to retract all three papers."
Also from [0], "As to the five reviewed papers where Dr. Tessier-Lavigne was a
principal author...Specifically, a group of three papers contain images that are the result of manipulation of research data (Cell ’99, Science ’01 Binding, Science ’01 Silencing)...A fourth primary paper also contains images (which Dr. Tessier-Lavigne did not personally prepare) that indicate manipulation of research data (Nature ’04)....The Panel understands that Dr. Tessier-Lavigne now intends to retract at least three publications on which he is a principal author".
For the four papers named in the quotes above, citations and links appear below [1-4]. I'd suggest reading [0] (as linked from OP's article) for more details. There are other papers discussed in [0], too.
