What is the status of research on gravitons and Higgs bosons?

    What is the present state of research on gravitons and Higgs bosons? How much has the research advanced?

    Not sure about gravitons, but regarding the Higgs, I'm curious. Have you not had any internet connection for the past 2 years, or have been insulated from any kind of news?

    In terms of gravitons, we cannot and will not ever detect them individually (while we can, and likely will, detect gravitational waves within the next few years).

    The question was posted here because there might be a particle physicist in the forum that might have data on the research so it might be easier to post a question in this forum and get the information directly from the source rather than taking the information indirectly from online references.

    I don't think that any ATLAS/CMS collaboration member would give you internal data here, so we are all limited to conference talks, publications and other presentations.
    As far as I know, there were no interesting updates on Higgs searches since december (which included the full 2011 data anyway), and I think you know the results presented there. Maybe ATLAS updated the data at the high mass region, but without interesting results.

    I would expect new things at the summer conferences, with a dataset similar to the one of 2011. Enough to see a bump at 125 GeV again, but not enough for the "magic 5 sigma", even in combinations.

    Gravitons: I didn't see any signs of extra dimensions, gravitons or other new stuff so far.

    It might have been helpful to specify, since when?

    Since 2011-2012.

    Hmm, I should have read my mails ;)

    ATLAS gave a presentation on the status of the Higgs searches yesterday. The exclusion limits at ~115-120 GeV and at the high mass region got a bit better, but apart from that, nothing new happened.

    And by research do you mean detection or understanding?
