Feasibility of ultrarelativistic bubbles in SMEFT
Upalaparna Banerjee, Sabyasachi Chakraborty, Suraj Prakash +1
A first order electroweak phase transition probes physics beyond the Standard Model on multiple frontiers and therefore is of immense interest for theoretical exploration. We condu…
Ultra-light dark matter explanation of NANOGrav observations
Debtosh Chowdhury, Arpan Hait, Subhendra Mohanty +1
The angular correlation of pulsar residuals observed by NANOGrav and other pulsar timing array (PTA) collaborations show evidence in support of the Hellings-Downs correlation expec…
Frequency space derivation of linear and non-linear memory gravitational wave signals from eccentric binary orbits
Arpan Hait, Subhendra Mohanty, Suraj Prakash
The memory effect in gravitational wave (GW) signals is the phenomenon, wherein the relative position of two inertial GW detectors undergoes a permanent displacement owing to the p…
Memories of quenches in operator mixing
Joydeep Chakrabortty, Diptarka Das, Bidyut Dey +2
We work perturbatively with an interacting quantum field theory comprised of two distinct scalar fields. In this theory, we introduce a sudden quench of the mass of one of the scal…
EFT Diagrammatica II: Tracing the UV origin of bosonic D6 CPV and D8 SMEFT operators
Wrishik Naskar, Suraj Prakash, Shakeel Ur Rahaman
In recent times, SMEFT, along with a superlative repertoire of theoretical and computational tools, has emerged as an efficacious platform to test the viability of proposed BSM sce…
EFT Diagrammatica: UV Roots of the CP-conserving SMEFT
Supratim Das Bakshi, Joydeep Chakrabortty, Suraj Prakash +2
Effective Field Theories are an established framework to bridge the gap between UV and low energy theories. In the context of the Standard Model, the bottom-up approach extends its…
Uncovering the Root of LEFT in SMEFT
Joydeep Chakrabortty, Suraj Prakash, Shakeel Ur Rahaman +1
At energies below the electroweak scale, baryon number and lepton number violating processes are of significant importance in identifying the nature of UV extensions of the…
Effective Operator Bases for Beyond Standard Model Scenarios: An EFT compendium for discoveries
Upalaparna Banerjee, Joydeep Chakrabortty, Suraj Prakash +2
It is not only conceivable but likely that the spectrum of physics beyond the Standard Model (SM) is non-degenerate. The lightest non-SM particle may reside close enough to the ele…
Characters and Group Invariant Polynomials of (Super)fields: Road to "Lagrangian"
Upalaparna Banerjee, Joydeep Chakrabortty, Suraj Prakash +1
The dynamics of the subatomic fundamental particles, represented by quantum fields, and their interactions are determined uniquely by the assigned transformation properties, i.e.,…
Hilbert Series and Plethystics: Paving the path towards 2HDM- and MLRSM-EFT
Anisha, Supratim Das Bakshi, Joydeep Chakrabortty +1
Effective Field Theory technique is one of the most elegant ways to capture the impact of high scale theory, if any, at some low energy by incorporating higher mass dimensional ($\…
