The Spurion Massive EFT (SMEFT)
Julian L. Northey, Yael Shadmi, Yotam Soreq +1
We use the amplitude formulation of the SMEFT to introduce a spurion analysis of the SMEFT low-energy amplitudes in terms of the Higgs VEV. Each SMEFT contact-term is given as a su…
On Exclusive Coherent Production of Bosons in Electron-Proton Collisions
Reuven Balkin, Ta'el Coren, Alexander Jentsch +4
We study the exclusive electroproduction process , with a single-particle final state, in the forward-proton kinematics relevant for the future Electron-Ion Col…
Blocking Mesogenesis
Chaja Baruch, Gilly Elor, Jared M. Goldberg +2
Mechanisms of Mesogenesis generate the baryon asymmetry and dark matter of the Universe through late-time decays of Standard Model mesons into baryons and dark matter states. Utili…
Atomic Spectroscopy Probes of New Physics
Cédric Delaunay, Jean-Philippe Karr, Yotam Soreq
Precision spectroscopy has long played a central role in testing the foundations of physics, from the early insights that led to the development of quantum mechanics to the validat…
Braking protons at the EIC: from invisible meson decay to new physics searches
Reuven Balkin, Ta'el Coren, Alexander Jentsch +4
We investigate the sensitivity of the Electron-Ion Collider~(EIC) to invisible final states in coherent exclusive electroproduction. The characteristic signal is a forward proton w…
A covariant description of the interactions of axion-like particles and hadrons
Reuven Balkin, Ta'el Coren, Yotam Soreq +1
We present a covariant framework for analyzing the interactions and decay rates of axion-like particles (ALPs) that couple to both gluons and quarks. We identify combinations of co…
Searching for exotic scalars at fusion reactors
Chaja Baruch, Patrick J. Fitzpatrick, Tony Menzo +3
The energy created in deuterium-tritium fusion reactors originates from a high-intensity neutron flux interacting with the reactor's inner walls. The neutron flux can also be used…
Probing new hadronic forces with heavy exotic atoms
Hongkai Liu, Ben Ohayon, Omer Shtaif +1
We explore the potential of precision spectroscopy of heavy exotic atoms where electrons are substituted by negative hadrons to detect new force carriers with hadronic couplings. T…
Light scalar beyond the Higgs mixing limit
Cédric Delaunay, Teppei Kitahara, Yotam Soreq +1
We explore the possibility that the interactions of a light scalar singlet, which mixes with the Standard Model~(SM) Higgs, also receive other UV contributions of comparable size.…
New Physics at the Muon (Synchrotron) Ion Collider: MuSIC for several scales
Hooman Davoudiasl, Hongkai Liu, Roman Marcarelli +2
A Muon (Synchrotron) Ion Collider (MuSIC) can be the successor to the Electron-Ion Collider at Brookhaven National Laboratory, as well as the ideal demonstrator facility for a futu…
Searching for hadronic scale baryonic and dark forces at 's lattice-vs-dispersion front
Kaustubh Agashe, Abhishek Banerjee, Minuyan Jiang +5
The anomalous magnetic moment of the muon () provides a stringent test of the quantum nature of the Standard Model (SM) and its extensions. To probe beyond the SM physics,…
Constraining P and T Violating Forces with Chiral Molecules
C. Baruch, P. B. Changala, Y. Shagam +1
New sources of parity and time reversal violation are predicted by well motivated extensions of the Standard Model and can be effectively probed by precision spectroscopy of atoms…
Constraining CP violating nucleon-nucleon long range interactions in diatomic eEDM searches
Chaja Baruch, P. Bryan Changala, Yuval Shagam +1
The searches for CP violating effects in diatomic molecules, such as and ThO, are typically interpreted as a probe of the electron's electric dipole moment ($e\text{…
