SND@LHC Upgrade for the High-Luminosity LHC: Physics Reach and Installation Scenarios
LHC Collaboration
The SND@LHC experiment is currently taking data at the Large Hadron Collider (LHC), exploring the unique forward region at pseudorapidities from 7.2 to 8.4. Its physics programme c…
Primordial Gravitational Wave Probes of Non-Standard Thermal Histories
Annet Konings, Mariia Marinichenko, Oleksii Mikulenko +1
Primordial gravitational waves propagate almost unimpeded from the moment they are generated to the present epoch. Nevertheless, they are subject to convolution with a non-trivial…
Quasi-Dirac Heavy Neutral Leptons in the Left-Right Symmetric Model
Oleksii Mikulenko
We discuss the phenomenology of a pair of degenerate GeV-scale Heavy Neutral Leptons within the Left-Right Symmetric Model (LRSM) framework, with the third fermion serving as a dar…
Unveiling new physics with discoveries at Intensity Frontier
Oleksii Mikulenko, Kyrylo Bondarenko, Alexey Boyarsky +1
The idea of feebly interacting particles (FIPs) has emerged as an important approach to address challenges beyond the Standard Model. The next generation of Intensity Frontier expe…
New physics at the Intensity Frontier: how much can we learn and how?
Oleksii Mikulenko, Kyrylo Bondarenko, Alexey Boyarsky +1
Intensity Frontier experiments are often evaluated by the smallest coupling it can probe, irrespective of what particle can be found or the scientific significance of its detection…
Sensitivities to feebly interacting particles: public and unified calculations
Maksym Ovchynnikov, Jean-Loup Tastet, Oleksii Mikulenko +1
The increasing interest in Long-Lived Particles (LLPs) has led to numerous proposed experiments in order to search for them. However, the sensitivity estimates published by these e…
Measuring lepton number violation in heavy neutral lepton decays at the future muon collider
Oleksii Mikulenko, Mariia Marinichenko
The future muon collider has the potential to discover feebly interacting particles in a wide range of masses above the electroweak scale. It is particularly suitable to search for…
Sensitivities to feebly interacting particles: public and unified calculations
Maksym Ovchynnikov, Jean-Loup Tastet, Oleksii Mikulenko +1
The idea that new physics could take the form of feebly interacting particles (FIPs) - particles with a mass below the electroweak scale, but which may have evaded detection due to…
Towards the optimal beam dump experiment to search for feebly interacting particles
Kyrylo Bondarenko, Alexey Boyarsky, Oleksii Mikulenko +2
Future searches for new physics beyond the Standard Model are without doubt in need of a diverse approach and experiments with complementary sensitivities to different types of cla…
Report of the Topical Group on Physics Beyond the Standard Model at Energy Frontier for Snowmass 2021
Tulika Bose, Antonio Boveia, Caterina Doglioni +318
This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More gen…
Exploring the potential of FCC-hh to search for particles from mesons
Alexey Boyarsky, Oleksii Mikulenko, Maksym Ovchynnikov +1
The Future Circular Collider (FCC-hh) is a proposed successor of the Large Hadron Collider (LHC). FCC-hh would push both the energy and intensity frontiers of searches for new phys…
The Present and Future Status of Heavy Neutral Leptons
Asli M. Abdullahi, Pablo Barham Alzas, Brian Batell +42
The existence of non-zero neutrino masses points to the likely existence of multiple SM neutral fermions. When such states are heavy enough that they cannot be produced in oscillat…
The Forward Physics Facility at the High-Luminosity LHC
Jonathan L. Feng, Felix Kling, Mary Hall Reno +233
High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing L…
Heisenberg's uncertainty principle in the PTOLEMY project: a theory update
PTOLEMY Collaboration, A. Apponi, M. G. Betti +58
We discuss the consequences of the quantum uncertainty on the spectrum of the electron emitted by the -processes of a tritium atom bound to a graphene sheet. We analyze quantita…
Searches for Long-Lived Particles at the Future FCC-ee
J. Alimena, P. Azzi, M. Bauer +15
The electron-positron stage of the Future Circular Collider, FCC-ee, is a frontier factory for Higgs, top, electroweak, and flavour physics. It is designed to operate in a 100 km c…
