So far MoEDAL has placed the world’s best published direct limits on:
Multiply charged magnetic monopoles
Spin-1 monopoles

DY + Photon fusion production of monopoles
Dyons – electrically and magnetically charged particles.

Monopoles From Heavy-ion Collisions
via the Schwinger Mechanism
Fields as high as 1016 Tesla
Magnetars as high as 1011 Tesla
• Schwinger mechanism originally described spontaneous creation
of e-- – e+ pairs in presence of an extremely strong electric field.
Probability of producing a monopole pair sMM = sInlVST GT (where
Vst is the space-time volume of the field, GT is the rate/unit volume & sinl is the
inelastic nuclear cross-section)
Important benefits:
• No exponential suppression for finite sized monopoles
• X-sec calculation does not suffer from non-perturbative couplings as in DY

The MOEDAL-MAPP Project
MOEDAL Phase-1
MAPP-2 Phase-3 55m
• Phase of Project
• Phase-1: MoEDAL + MAPP-mQP;
• Phase-2: MAPP-1 + MALL;
• Phase-3: MAPP-2 (MAPP-1 extended)
• Phase 1 & 2 Run-3
MAPP Phase-1/2 • Phase-3 Run-4 & beyond
MoEDAL-MAPP Expt Approval for Run-3
MoEDAL MAPP
On track for full approval in 2021 UGC1 gallery must be upgraded
to start data taking in 2022 to house MAPP in 2021/22
Envisage approval in 2022 and
the start of data taking in 2023
Phase 1a: MoEDAL for Run-3
Very similar to the Run-2 detector** deployed from 2015-2018
Running to benefit for higher Ecm and factor of 5 higher luminosity in Run-3
There continue to be 4 independent subdetectors:
Nuclear Track Detectors (NTDs) consisting of stacks of plastic
Magnetic Monopole Trappers (MMTs) composed of aluminum bars
TimePix3 devices which are active silicon particle detectors
High Charge Catcher (HCC) a thin low mass NTD (if agreed by LHCb)
10Phase-1b MAPP-mQP for Run-3 UGC1 Tunnel MAPP-mQP Weight 4-5 tonnes, size ~1.5 X 2.5 x 4.0m3 400 scintillator bars (10 x 10 x 75 cm3) in 4 sections readout by 400 low noise PMTs Scintillator based doesn’t require gas or HV (CW bases) Uses SW (FPGAs) trigger and is readout over the internet Operates in a standalone mode in the Scintillator bar basic unit UGC1 cavern
The MAPP-mQP Outrigger (in plan) Lower sensitivity to smaller fractional charges but much larger area: ~16m deployed in 4 layers Greater reach at larger fractional charges

When Phase-2 is
installed (2022/23)
we will be able to
search for LLPs
HIPs mCPsMAPP-1 (LLP): Example Physics Studies
Benchmark process:
Where the Higgs mixing portal
admits inclusive B → Xsf decays,
where φ is a light CP-even
scalar that mixes with the
Higgs, with mixing angle θ ≪ 1.

300 fb-1 compared to CODEX-b
Bottom: Reach for 30 fb-1 /300
fb-1 compared to SHIP (3ab-1) Sin2q
& MATHUSLA (3ab-1)
Valuable complementarity with
MATHUSLA & CODEX-b
See Phys. Rev. D97 (1) (2018) 15023 for CODEX-b results.Phase-3: MAPP-2 for HL-LHC MAPP-2 is an extension of MAPP-1 down the UGC1 gallery. The MAPP-I technology would be used to provide a cost effective approach.
MAPP-2 (LLP): Example Physics Studies
Using the same Higgs mixing
portal benchmark we see that
MAPP-2 extends MAPP-1’s
sensitivity so that it is competitive
with SHIP’s.

Highly ionizing particles (HIPs)
IJMPA, September 2014, Vol. 29, No. 23
With MAPP the MoEDAL Experiment will be Long-Lived Particles (LLPs)
sensitive to 3 clear avatars of new physics:
HIPs, mQPs and LLPs.
MAPP allows us expand the physics reach of
our existing program to include dark sector
models, hidden valley models, etc. Mini-charged particles (mQPs)You can also read
