Phenomenological Consequences of the Refined Swampland Conjecture
  We discuss phenomenological consequences of the recently-introduced
refinements of the de Sitter swampland conjecture. The conjecture constraints
the first and the second derivatives of the scalar potential in terms of two
$O(1)$ constants $c$ and $c'$, leading to interesting constraints on particle
phenomenology, especially inflationary model building. Our work can also be
regarded as bottom-up constraints on the values of $c$ and $c'$.
