Quirks

Quirks are exotic vector-like fermions that transform as a fundamental under a hidden confining group, but also carry Standard Model charges.

Quirks!

The quirk mass M is much larger than the confinement scale Λ.

  • Signatures Catalogue

    • Quirks with strange curvature in the B-field of the detectors

    • Quirks emitting many soft photons

    • Quirks emitting many soft hadrons

    • Quirks emitting glueballs

    • Quirks loosing energy in the detector (like R-Hardons?)

    • Quirks causing displaced vertices

    • Quirk pairs causing unusual ionization.

    • Timing of the signals?

Macroscopic strings!?!


Macro strings at the lhc
Macro-Strings at the LHC? fundamental under a hidden confining group, but also carry Standard Model charges.

New strong interactions with small  & new quarks mQ> several hundered GeV

Markus Luty/Aspen 07

 Strings do not break up  Stringy objects in the detector.

 End points are massive quarks (quirks)

 The strings can oscillate strange signature in detectors


Proposal
Proposal fundamental under a hidden confining group, but also carry Standard Model charges.

  • Quirks move ‘connected’ through the magnetic field. Weird signatures.

  • Can G4 be made to deal with such a case?

  • If yes: Markus Luty (UC-Davis) interested in collaborating with 2 graduate students

  • More details in

    • Macroscopic Strings and 'Quirks' at Colliders.Junhai Kang, Markus A. Luty . arXiv:0805.4642


Backup

Backup fundamental under a hidden confining group, but also carry Standard Model charges.


Quirk signatures
Quirk Signatures fundamental under a hidden confining group, but also carry Standard Model charges.

Particles remain connected with a ‘string’

 Strange curvature in the detector

M. Luty


Quirk signatures1
Quirk Signatures fundamental under a hidden confining group, but also carry Standard Model charges.

Particles remain connected with a short ‘string’

 Bound state moves through the detector

M. Luty


Quirk signatures2
Quirk Signatures fundamental under a hidden confining group, but also carry Standard Model charges.

Particles yoyo around and loose energy

 emission of many soft harons, photons, and possible glueballs

M. Luty

All these signatures

are challenging

for the experiments

starting with the

trigger


Quirks shower photons
Quirks shower photons fundamental under a hidden confining group, but also carry Standard Model charges.
