  In the present letter we use holographic methods to show that a very intense
magnetic field lowers the temperature at which the mesons melt and decreases
the mass gap of the spectrum along with their masses. Consequently, there is a
range of temperatures for which mesons can be melted by applying a magnetic
field instead of increasing the temperature. We term this effect Magnetic Meson
Melting (MMM), and we are able to observe it by constructing a configuration
that makes it possible to apply gauge/gravity methods to study fundamental
degrees of freedom in a quark-gluon plasma subject to a magnetic field as
intense as that expected in high energy collisions. This is achieved by the
confection of a ten-dimensional background that is dual to the magnetized
plasma and nonetheless permits the embedding of D7-branes in it. For such a
background to exist, a scalar field has to be present and hence a scalar
operator of dimension 2 appears in the gauge theory. We present here the
details of the background and of the embedding of flavor D7-branes in it. Since
our results are obtained from the gravity dual of the gauge theory, the
analysis is also interesting from the gravitational perspective.
