Impact of model-independent higher-order contributions to the Higgs-boson self-couplings
Johannes Braathen, Wrishik Naskar, Georg Weiglein
We point out the relevance of a new class of model-independent higher-order contributions to the trilinear and quartic self-couplings of the detected Higgs boson giving rise to pot…
Kinematic Riffs and Interference Effects in Triple Higgs Production in the N2HDM
Wrishik Naskar, Tania Robens, Julia Anabell Ziegler
We investigate the complex kinematic structure involved in resonant production of three Higgs bosons at the Large Hadron Collider (LHC), within the rich scalar spectra of the Next-…
On the Robustness of type-II Seesaw Collider Searches
Christoph Englert, Manimala Mitra, Wrishik Naskar +1
Electroweak triplet Higgs sector extensions are well-motivated scenarios to address lepton flavour observations. These models can also be strongly constrained by combining precise,…
Weak boson probes of Higgs unitarity restoration at 10 TeV parton colliders
Christoph Englert, Wrishik Naskar, Andrew D. Pilkington +1
Higgs coupling deviations, at levels accessible to the high-luminosity LHC, can imply a phenomenological no-lose theorem for the next generation of collider facilities. Correlating…
Assessing (H)EFT theory errors by pitting EoM against Field Redefinitions
Rodrigo Alonso, Christoph Englert, Wrishik Naskar +1
Truncations of effective field theory expansions are technically necessary but inherently intertwined with the redundancies of general field redefinitions. This can be viewed as a…
A anomaly motivated boson at the energy and precision frontiers
Ben Allanach, Christoph Englert, Wrishik Naskar
TeV-scale bosons with family-dependent couplings can explain some anomalies inferred from meson measurements of processes involving the $b \rightarrow s \ell^+\ell^-…
Early Career Researcher Input to the European Strategy for Particle Physics Update: White Paper
Jan-Hendrik Arling, Alexander Burgman, Christina Dimitriadi +42
This document, written by early career researchers (ECRs) in particle physics, aims to represent the perspectives of the European ECR community and serves as input for the 2025--20…
Impact of New Physics on Momentum-Dependent Particle Widths and Propagators
Christoph Englert, Wrishik Naskar, Michael Spannowsky
We investigate the impact of momentum-dependent particle widths and propagators on gauge and Higgs bosons and the top quark within the Standard Model (SM) and its SMEFT extensions…
Doubling down on down-type diquarks
Christoph Englert, Christiane Mayer, Wrishik Naskar +1
Effective field theory-based searches for new physics at colliders are relatively insensitive to interactions involving only right-handed down-type quarks. These interactions can h…
Double and Triple Higgs Production to probe the Electroweak Phase Transition
Lisa Biermann, Christoph Borschensky, Christoph Englert +2
The production of three Higgs bosons could be a stretch goal for the LHC and a strategic case for future colliders. In this work, we analyse the phenomenological prospects of (neut…
Resurrecting the LHC discovery potential in the extended Type-II Seesaw Model
Upalaparna Banerjee, Christoph Englert, Wrishik Naskar
The juxtaposition of the precision of lepton flavour measurements and the limited energy range of the Large Hadron Collider (LHC) to discover dynamical degrees of freedom linked to…
Equivariant, Safe and Sensitive -- Graph Networks for New Physics
Akanksha Bhardwaj, Christoph Englert, Wrishik Naskar +2
This study introduces a novel Graph Neural Network (GNN) architecture that leverages infrared and collinear (IRC) safety and equivariance to enhance the analysis of collider data f…
BSM patterns in scalar-sector coupling modifiers
Christoph Englert, Wrishik Naskar, Dave Sutherland
We consider what multiple Higgs interactions may yet reveal about the scalar sector. We estimate the sensitivity of a Feynman topology-templated analysis of weak boson Higgs pair p…
EFT, decoupling, Higgs boson mixing, and higher dimensional operators
Upalaparna Banerjee, Joydeep Chakrabortty, Christoph Englert +3
The effective field theory (EFT) framework is a precise approximation procedure when the inherent assumptions of a large-scale separation between the Standard Model (SM) and new in…
On the BSM reach of four top production at the LHC
Anisha, Oliver Atkinson, Akanksha Bhardwaj +3
Many scenarios of beyond the Standard Model (BSM) physics give rise to new top-philic interactions that can be probed at proton machines such as the Large Hadron Collider through a…
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…
