The Swampland Conjectures: A Bridge from Quantum Gravity to Particle Physics

The Swampland Conjectures: A Bridge from Quantum Gravity to Particle Physics

The swampland is the set of seemingly consistent low-energy effective field theories that cannot be consistently coupled to quantum gravity. In this review we cover some of the conjectural properties that effective theories should possess in order not to fall in the swampland, and we give an overvie...
