Hunting muonic forces at emulsion detectors
Akitaka Ariga, Reuven Balkin, Iftah Galon +2
Only two types of Standard Model particles are able to propagate the meters separating the ATLAS interaction point and FASER: neutrinos and muons. Furthermore, muons are cop…
Dark Photons and Displaced Vertices at the MUonE Experiment
Iftah Galon, David Shih, Isaac R. Wang
MUonE is a proposed experiment designed to measure the hadronic vacuum polarization contribution to muon through elastic scattering. As such it employs an extremely hig…
Synchrotron-Like Radiation Beyond The Standard Model I: Hunting for new physics with the Sokolov-Ternov effect
Iftah Galon
Electron and positron beams in storage-rings self-polarize by emitting spin-flipping synchrotron radiation. If new ultralight particles couple to , their emission in synchro…
Searching for muonic forces with the ATLAS detector
Iftah Galon, Enrique Kajamovitz, David Shih +2
The LHC copiously produces muons via different processes, and the muon sample will be large at the high-luminosity LHC (HL-LHC). In this work we propose to leverage this large muon…
FASER's Physics Reach for Long-Lived Particles
FASER Collaboration, Akitaka Ariga, Tomoko Ariga +25
FASER,the ForwArd Search ExpeRiment,is a proposed experiment dedicated to searching for light, extremely weakly-interacting particles at the LHC. Such particles may be produced in…
ALPs at FASER: The LHC as a Photon Beam Dump
Jonathan L. Feng, Iftah Galon, Felix Kling +1
The goal of FASER, ForwArd Search ExpeRiment at the LHC, is to discover light, weakly-interacting particles with a small and inexpensive detector placed in the far-forward region o…
Dark Higgs Bosons at FASER
Jonathan L. Feng, Iftah Galon, Felix Kling +1
FASER, ForwArd Search ExpeRiment at the LHC, has been proposed as a small, very far forward detector to discover new, light, weakly-coupled particles. Previous work showed that wit…
FASER: ForwArd Search ExpeRiment at the LHC
Jonathan L. Feng, Iftah Galon, Felix Kling +1
New physics has traditionally been expected in the high- region at high-energy collider experiments. If new particles are light and weakly-coupled, however, this focus may be…
US Cosmic Visions: New Ideas in Dark Matter 2017: Community Report
Marco Battaglieri, Alberto Belloni, Aaron Chou +248
This white paper summarizes the workshop "U.S. Cosmic Visions: New Ideas in Dark Matter" held at University of Maryland on March 23-25, 2017.
Dark sectors and enhanced transitions
Iftah Galon, Jure Zupan
LHC searches with leptons in the final state are always inclusive in missing-energy sources. A signal in the flavor-violating Higgs decay search, , could therefore equa…
Lepton-Flavor Violating Mediators
Iftah Galon, Anna Kwa, Philip Tanedo
We present a framework where dark matter interacts with the Standard Model through a light, spin-0 mediator that couples chirally to pairs of different-flavor leptons. This flavor…
as a Probe of the Magnetic Dipole Moment
Iftah Galon, Arvind Rajaraman, Tim M. P. Tait
Low energy observables involving the Standard Model fermions which are chirality-violating, such as anomalous electromagnetic moments, necessarily involve an insertion of the Higgs…
Particle Physics Models for the 17 MeV Anomaly in Beryllium Nuclear Decays
Jonathan L. Feng, Bartosz Fornal, Iftah Galon +4
The 6.8 anomaly in excited 8Be nuclear decays via internal pair creation is fit well by a new particle interpretation. In a previous analysis, we showed that a 17 MeV protophobi…
Protophobic Fifth Force Interpretation of the Observed Anomaly in Be Nuclear Transitions
Jonathan L. Feng, Bartosz Fornal, Iftah Galon +4
Recently a 6.8 anomaly has been reported in the opening angle and invariant mass distributions of pairs produced in nuclear transitions. The data are exp…
Gluino Meets Flavored Naturalness
Monika Blanke, Benjamin Fuks, Iftah Galon +1
We study constraints from LHC run I on squark and gluino masses in the presence of squark flavor violation. Inspired by the concept of `flavored naturalness', we focus on the impac…
Charged Slepton Flavor post the 8 TeV LHC: A Simplified Model Analysis of Low-Energy Constraints and LHC SUSY Searches
Lorenzo Calibbi, Iftah Galon, Antonio Masiero +2
Motivated by the null results of LHC searches, which together with the Higgs mass, severely constrain minimal supersymmetric extensions of the standard model, we adopt a model-inde…
Non-Degenerate Squarks from Flavored Gauge Mediation
Iftah Galon, Gilad Perez, Yael Shadmi
We study the squark spectra of Flavored Gauge Mediation Models, in which messenger-matter superpotential couplings generate new, generation-dependent contributions to the squark ma…
Flavored Gauge Mediation, A Heavy Higgs, and Supersymmetric Alignment
Mohammad Abdullah, Iftah Galon, Yael Shadmi +1
We show that the messenger-matter couplings of Flavored Gauge Mediation Models can generate substantial stop mixing, leading to Higgs masses around 126 GeV with colored superpartne…
When a Muon Is Not a Muon--- Detecting Fast Long-Lived Charged Particles from Cascade Decays Using a Mass Scan
Iftah Galon, Yael Shadmi, Shahrazad Tarboush +1
If produced at the LHC, long-lived charged particles (LLCPs) would leave tracks in the muon detector. Time-of-Flight based methods for detecting these particles become less efficie…
Kinematic Edges with Flavor Splitting and Mixing
Iftah Galon, Yael Shadmi
The kinematic edges of invariant mass distributions provide an important tool for the possible measurements of superpartner masses in supersymmetric models with a neutralino LSP. W…
Measuring Slepton Masses and Mixings at the LHC
Jonathan L. Feng, Sky T. French, Iftah Galon +5
Flavor physics may help us understand theories beyond the standard model. In the context of supersymmetry, if we can measure the masses and mixings of sleptons and squarks, we may…
