Renormalizing the euclidean Dirac-Born-Infeld action in the antipodal limit, we find for the confined and deconfined phases positive contributions to the pressures that grow with the magnetic field. We also obtain positive magnetic susceptibilities indicating a paramagnetic behaviour of quarks. Using these results we estimate a \\lambda^2/N_c correction to the deconfinement temperature that decreases as a function of the magnetic field.", "revisions": [ { "version": "v4", "updated": "2013-11-25T11:30:44.000Z" } ], "analyses": { "keywords": [ "magnetic field", "holographic deconfinement transition", "euclidean dirac-born-infeld action", "deconfinement temperature", "flavour sector" ], "tags": [ "journal article" ], "publication": { "publisher": "Springer", "journal": "Journal of High Energy Physics", "year": 2013, "month": "Nov", "volume": 2013, "pages": 168 }, "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1244336, "adsabs": "2013JHEP...11..168B" } } }
