Forays into the dark side of the swamp
Iason Baldes, Debtosh Chowdhury, Michel H. G. Tytgat
Motivated by the swampland conjectures, we study cosmological signatures of a quintessence potential which induces time variation in the low energy effective field theory. After de…
BPS solutions for generalised Wess-Zumino models and their applications
Steven Abel, Quentin Bonnefoy, Debtosh Chowdhury
We present BPS solutions to a general class of Wess-Zumino models which extend previous results in the literature. We discuss their relation to amplitudes on threshold, and their a…
Dark matter seeping through dynamic gauge kinetic mixing
Avik Banerjee, Gautam Bhattacharyya, Debtosh Chowdhury +1
We show for the first time that the loop-driven kinetic mixing between visible and dark Abelian gauge bosons can facilitate dark matter production in the early Universe by creating…
Moduli Portal Dark Matter
Debtosh Chowdhury, Emilian Dudas, Maíra Dutra +1
We show that moduli fields as mediators between the Standard Model and the dark sector can naturally lead to the observed relic abundance. Indeed, even if moduli are very massive,…
