Heavy neutral leptons from light scalar in fixed target and forward search experiments

ShivaSankar K. A., Souvik Das, Arindam Das +1

The observation of neutrino masses strongly motivates extensions of the Standard Model, in which heavy neutral leptons acquire Majorana masses through spontaneous $U(1…

Quantum spin correlations in -mediated production at future lepton colliders

ShivaSankar K. A., Arindam Das, Sanjoy Mandal

We study quantum spin correlations in top-quark pair production at future lepton colliders in the presence of a neutral gauge boson from anomaly-free general extensions of t…

Forward Searches for Heavy Neutrinos and Bosons at FCC-hh

ShivaSankar K. A., Souvik Das, Arindam Das +1

The discovery of neutrino masses strongly motivates extensions of the Standard Model containing heavy neutral leptons and additional gauge interactions. We investigate the prospect…

Particle and Gravitational Wave Probes of Minimal Seesaw Neutrinos

Sanjoy Mandal, Rishav Roshan, Jose W. F. Valle

Observable gravitational waves (GWs) from first-order phase transitions (FOPTs) can coexist with distinct particle physics signatures. These include same-sign dilepton plus four~je…

Probing Inelastic Dark Matter via Cosmic-Ray Upscattering in NGC 1068

Eung Jin Chun, Sanjoy Mandal, Abhishek Roy

We study constraints on sub-GeV inelastic dark matter (iDM) from cosmic-ray (CR) cooling in the active galactic nucleus (AGN) NGC 1068. In dense dark matter (DM) spikes surrounding…

Probing lepton number violation at FCC-ee

Praveen Bharadwaj, Sanjoy Mandal, Rojalin Padhan +1

We propose high-multiplicity final-state signatures, such as with denoting , , as probes of lepton number violation (LN…

Right handed neutrino production from interactions in forward search experiments

ShivaSankar K. A, Souvik Das, Arindam Das +1

We study two general extensions of the Standard Model (SM) those generate tiny neutrino masses via the seesaw mechanism after general breaking. These models predict a…

Dark matter as the source of neutrino mass: theory overview and experimental prospects

Ivania M. Ávila, Anirban Karan, Sanjoy Mandal +2

We review theoretical frameworks in which small neutrino masses arise radiatively through interactions with a dark sector that also accounts for cosmological dark matter (DM). A pr…

New Physics Search at the CEPC: a General Perspective

Xiaocong Ai, Stefan Antusch, Peter Athron +211

The Circular Electron-Positron Collider (CEPC), a proposed next-generation Higgs factory, provides new opportunities to explore physics beyond the Standard Model (SM). With its cle…

Reinterpretation and preservation of data and analyses in HEP

Jon Butterworth, Sabine Kraml, Harrison Prosper +145

Data from particle physics experiments are unique and are often the result of a very large investment of resources. Given the potential scientific impact of these data, which goes…

Phenomenology of Dirac neutrino EFTs up to dimension six

Anirban Biswas, Eung Jin Chun, Sanjoy Mandal +1

The gauge-singlet right-handed neutrinos would be essential to explain the tiny masses of active neutrinos. We consider the effective field theory of the Standard Model extended wi…

Testing tree level TeV scale seesaw scenarios in TRISTAN

Arindam Das, Jinmian Li, Sanjoy Mandal +2

We investigate TeV scale seesaw scenarios at and colliders in the TRISTAN experiment. In minimal type-I seesaw scenario we consider two generations of Standa…

Dark matter-electron scattering and freeze-in scenarios in the light of mediation

Basabendu Barman, Arindam Das, Sanjoy Mandal

We investigate dark matter (DM)-electron scattering in a minimal extension of the Standard Model (SM), where the DM can appear as a Majorana fermion, a complex singlet sca…

Collider imprints of right handed neutrino magnetic moment operator

Eung Jin Chun, Sanjoy Mandal, Rojalin Padhan

We consider most general effective Lagrangian up to dimension five, built with Standard Model~(SM) fields and right-handed neutrinos~(RHNs) . Assuming that the RHNs are presen…
