Freeze-in of anapole and charge-radius inelastic dark matter: X-ray probes of a decoupled vector portal
Krzysztof Jodłowski, Chih-Ting Lu
We study freeze-in production and experimental probes of inelastic dark matter (iDM) coupled to the Standard Model through dimension-6 transition anapole and charge-radius operator…
The DAMSA Experiment
Prithak Bhattarai, Andrew Brandt, Alan Bross +41
DAMSA (DArk Messenger Searches at an Accelerator) is a novel short-baseline accelerator/beam dump experiment aimed at probing short-lived physics processes, including searches for…
Impact of flavor changing processes on prospects for majoron discovery at intensity-frontier searches
Krzysztof Jodłowski, Chih-Ting Lu
The singlet majoron is the pseudo-Nambu-Goldstone boson of a spontaneously broken global symmetry that generates Majorana masses for right-handed neutrinos. Its tr…
DAMSA Experiment Conceptual Design White Paper
Prithak Bhattarai, Andrew Brandt, Alan Bross +41
DAMSA (DArk Messenger Searches at an Accelerator) is a novel short-baseline accelerator experiment aimed at probing short-lived physics processes, including searches for evidence o…
Is a covariant virtual tachyon viable?
Krzysztof Jodłowski
Sidney Coleman has noted that superluminal particles or observers would be able to go back in time and have no definite trajectory according to subluminal observers, while not viol…
Searches for Power-Law Warped Extra Dimensions
Sang Hui Im, Krzysztof Jodłowski
Extra dimensions with a bulk dilaton field can be power-law warped, unlike the exponential warping in the Randall-Sundrum (RS) model. We show that this mildly warped extra dimensio…
Dark axion portal at boson factories
Krzysztof Jodłowski
Dark axion portal connects an axion-like-particle (ALP), which can be the QCD axion, with the SM by the coupling to a photon and a dark photon, leading to a rich and distinct pheno…
Covariant quantum field theory of tachyons is unphysical
Krzysztof Jodłowski
Tachyons have fascinated generations of physicists due to their peculiar behavior, but they did not solve any real physical problem. This may have changed with the recent works of…
Exploring CP Violation beyond the Standard Model and the PQ Quality with Electric Dipole Moments
Kiwoon Choi, Sang Hui Im, Krzysztof Jodłowski
In some models of physics beyond the Standard Model (SM), one of the leading low energy consequences of the model appears in the form of the chromo-electric dipole moments (CEDMs)…
Looking forward to photon-coupled long-lived particles IV: neutralino-ALPino/gravitino
Krzysztof Jodłowski
Various supersymmetric (SUSY) scenarios predict a sub-GeV neutralino decaying into a single photon and an invisible state. This signature has recently been studied in a number of i…
Looking forward to photon-coupled long-lived particles II: dark axion portal
Krzysztof Jodłowski
The dark axion portal is a dimension-5 coupling between an axion-like particle (ALP), a photon, and a dark photon, which is one of the targets of the intensity frontier searches lo…
Looking forward to inelastic DM with electromagnetic form factors at FASER and beam dump experiments
Krzysztof Jodłowski
Inelastic Dark Matter (iDM) is an interesting thermal DM scenario that can pose challenges for conventional detection methods. However, recent studies demonstrated that iDM coupled…
Probing some photon portals to new physics at intensity frontier experiments
Krzysztof Jodłowski
A number of extensions of the Standard Model predict the existence of new light, weakly-coupled particles that couple to the visible sector through higher-dimensional operators con…
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…
Indirect detection of long-lived particles in a rich dark sector with a dark vector portal
Krzysztof Jodłowski, Leszek Roszkowski, Sebastian Trojanowski
Simplified models of light new physics provide a convenient benchmark for experimental searches for new physics signatures, including dark matter (DM). However, additional detectio…
Self-interacting dark matter from late decays and the tension
Krzysztof Jodłowski
We investigate a mechanism for the production of self-interacting dark matter based on WIMP-like messenger state decays into dark matter and dark radiation occurring after recombin…
The Forward Physics Facility: Sites, Experiments, and Physics Potential
Luis A. Anchordoqui, Akitaka Ariga, Tomoko Ariga +78
The Forward Physics Facility (FPF) is a proposal to create a cavern with the space and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider dur…
Neutrino beam-dump experiment with FASER at the LHC
Krzysztof Jodłowski, Sebastian Trojanowski
The neutrino physics program at the LHC, which will soon be initiated by the FASER experiment, will provide unique opportunities for precision studies of neutrino interaction verti…
Self-interacting dark matter from late decays and the tension
Andrzej Hryczuk, Krzysztof Jodłowski
We study a dark matter production mechanism based on decays of a messenger WIMP-like state into a pair of dark matter particles that are self-interacting via exchange of a light me…
Extending the reach of FASER, MATHUSLA, and SHiP towards smaller lifetimes using secondary particle production
Krzysztof Jodłowski, Felix Kling, Leszek Roszkowski +1
Many existing or proposed intensity-frontier search experiments look for decay signatures of light long-lived particles (LLPs), highly displaced from the interaction point, in a di…
