The " Crisis in Fundamental Physics " -will the Lhc Pomeron End It ? *
نویسنده
چکیده
SU(5) gauge theory with massless left-handed fermions in the representation 5 ⊕ 15 ⊕ 40 ⊕ 45 * (QUD) may have a bound-state S-Matrix that, uniquely, contains the asymptotically unitary Critical Pomeron and which might also reproduce the full Standard Model. If so, QUD would provide an underlying unification for the Standard Model in which very similar massless fermion anomaly dynamics is responsible for the physics of the strong and electroweak interactions and all particle masses are generated dynamically. The color sextet quark sector, responsible for both electroweak symmetry-breaking and dark matter in QUD, is predicted to produce large cross-section effects at the LHC, with the pomeron as a vital diagnostic-via TOTEM/CMS and FP420. In this talk, the multi-regge construction of high-energy QUD amplitudes is outlined as is, briefly, the LHC pomeron physics. Surrounding motivational issues (particularly outstanding QCD problems) and consequences are also discussed. The S-Matrix anomaly physics is conceptually and philosophically radical with respect to the current theory paradigm. As a consequence, QUD could provide a welcome way out of the current " Crisis in Fundamental Physics " with, potentially, it's novel physical applicability resolving a variety of Standard Model and, perhaps also, cosmology problems-it has zero vacuum energy.

Physics with tagged forward protons at the LHC
We emphasize the importance of tagging the outgoing forward protons to sharpen the predictions for New Physics at the LHC (such as the diffractive production of a light Higgs boson). The rescattering effects lead to a rich distinctive structure of the cross section as a function of the transverse momenta of the protons. We show that a study of the correlations between the proton transverse mome...
متن کاملRates for rapidity gap Higgs production †
We present model-independent estimates of the signal-to-background ratio for Higgs → bb̄ detection in double-diffractive events at the Tevatron and the LHC. For the missingmass approach to be able to identify the Higgs boson, it will be necessary to tag the b quark jets in the central region. The signal is predicted to be very small at the Tevatron, but observable at the LHC. We note that the do...
متن کاملDouble Pomeron Physics at the LHC
I discuss central exclusive production, also known as Double Pomeron Exchange,DIPE , from the ISR through the Tevatron to the LHC. There I emphasize the interest of exclusive Higgs and W+W−/ZZ production.
متن کاملSearch for Exclusive Events Using the Dijet Mass Fraction at the Tevatron
Double pomeron exchange (DPE) processes are expected to extend the physics program at the LHC not only due to the possible Higgs boson detection but also because of the possibility to study broader range of QCD physics and diffraction [1, 2, 3, 4, 5, 6, 7, 8]. The processes are theoreticaly characterized by large rapidity gap regions devoid of particles between centrally produced heavy object a...
متن کاملDiffractive Production at Collider Energies and Factorization
The most important consequence of Pomeron being a pole is the factorization property. However, due to Pomeron intercept being greater than 1, the extrapolated single diffraction dissociation cross section based on a classical triple-Pomeron formula is too large leading to a potential unitarity violation at Tevatron energies, which has been referred to as “Dino’s paradox”. We review our resoluti...
