The idea to install detectors far from the interaction point at CMS and/or ATLAS with the capacity to detect protons scattered through small angles has gained a great deal of attention in recent years and the report presented in [1] constitutes a significant milestone on the road to CEP physics at the LHC. In this talk, I should like to focus attention in particular on Higgs boson production, a...

We study in a framework of QCD collinear factorization the processes of a pion and a photon diffraction dissociation into two jets. The structure of non-factorizable contributions is discussed. We argue that coherent production of hard dijets by linearly polarized real photons can provide direct evidence for chirality violation in hard processes, the first measurement of the magnetic susceptibi...

We show that forward proton tagging may significantly enlarge the potential of studying the Higgs sector at the LHC. We concentrate on Higgs production via central exclusive diffractive processes (CEDP). Particular attention is paid to regions in the MSSM parameter space where the partial width of the Higgs boson decay into two gluons much exceeds the SM case; here the CEDP are found to have sp...

The processes of a light neutral vector meson, V = ρ 0 , ω, φ, electroproduction and a heavy quarkonium, V = J/Ψ, Υ, photoproduction are studied in the framework of QCD factorization. We derive a complete set of hard-scattering amplitudes which describe these processes at next-to-leading order (NLO).

In CDF we have observed several exclusive processes: γγ → e+e− and μ+μ−, γ + IP → J/ψ,ψ(2S), and IP + IP → χc. The cross sections agree with QED, HERA photoproduction data, and theoretical estimates of gg → χc with another gluon exchanged to screen the color. This observation of exclusive χc, together with earlier observations of exclusive dijets and exclusive γγ candidates, support some theore...

We compare results of our studies [1,2] on vector meson production within the QCD factorization at next-to-leading order with HERA data. 1 Introduction The exclusive vector meson V electro-and photo-productions in photon-proton collisions , γ p → V p, are the subject of HERA collider experiments. The primary motivation for the interests in these processes, both for the light ρ−meson electro-pro...

We propose a new variable, Rj , in order to identify exclusive double-diffractive high ET dijet production. The variable Rj is calculated using the transverse energy ET and pseudorapidity of the jet with the largest ET . For a purely exclusive event the value of Rj → 1, if we were to neglect hadronisaton and the detector resolution effects. To illustrate the expected Rj-distribution we also com...

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.

After the permanent demarcation of Exclusive Economic Zone boundaries with Myanmar and India through International Tribunal for Law Sea United Nations Convention on Sea, Bangladesh has exclusive rights to exploit explore marine resources across 118,813 km2 in Bay Bengal. To reap economic benefits from maritime space, government recently emphasized development a blue economy. Maritime activities...
