AB  - <jats:title>                    A                    <jats:sc>bstract</jats:sc>                  </jats:title>                  <jats:p>                    We study worldsheet instantons in holographic type IIA backgrounds directly in string theory. The first background is a dimensional reduction of AdS                    <jats:sub>7</jats:sub>                    ×                    <jats:italic>S</jats:italic>                    <jats:sup>4</jats:sup>                    and is dual to the maximally supersymmetric Yang-Mills theory on                    <jats:italic>S</jats:italic>                    <jats:sup>5</jats:sup>                    . The second background is AdS                    <jats:sub>4</jats:sub>                    ×                    <jats:bold>C</jats:bold>                    <jats:italic>P</jats:italic>                    <jats:sup>3</jats:sup>                    dual to ABJM in the type IIA limit. We compute the one-loop partition function of the fundamental string in these backgrounds and show that the result is in exact agreement with field theory predictions. We argue that for higher rank instantons, the string partition function takes a product form of the single instanton partition function times the contribution of two orbifolds on the worldsheet. We determine the orbifold factor to be                    <jats:italic>n</jats:italic>                    <jats:sup>                      <jats:italic>−</jats:italic>                      3/2                    </jats:sup>                    where                    <jats:italic>n</jats:italic>                    is the instanton rank. With this result, we reproduce the series of non-perturbative corrections in                    <jats:italic>α</jats:italic>

Note to staff:  Adding new publications to a research group

  1. Log in to Symplectic.
  2. Click on Menu > Create Links
  3. Choose what you want to create links between – in this case ‘Publications’ and ‘Organisational structures’.
  4. Choose the organisational structure (research group) into which you want to link the publications and check the box next to it.
  5. Now check the box of any publication you want to add to that group. You can use the filters to find what you want and select multiple publications if necessary. 
  6. Scroll to the bottom and click the blue ‘Create new link’ button to link them.
  7. The publications will be added to the group, and will be displayed on the group publications feed within 24 hours (it is not immediate).

Any problems, talk to Tim Evans or the Faculty Web Team.
