Exclusive photoproduction of $\rho^0(770)$ mesons is studied using the H1 detector at the $ep$ collider HERA. A sample of about 900000 events is used to measure single- and double-differential cross sections for the reaction $\gamma{}p\to \pi^{+}\pi^{-}Y$. Reactions where the proton stays intact ($m_Y=m_p$) are statistically separated from those where the proton dissociates to a low-mass...
Recent results of soft and small-x QCD measurements with the CMS experiment, such as minimum bias/underlying event physics, Double Parton Scattering and forward jet production.
Photon-photon fusion is a rare process at hadron and ion colliders. It is particularly interesting as a remarkably clean interaction with little (if any) remnant activity from the interacting particles. In this talk we present the status of photon-photon fusion measurements at the ATLAS detector. We present differential measurements of the light-by-light scattering process, γγ → γγ, in...
We describe an analysis comparing the $p\bar{p}$ elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96~TeV to that in $pp$ collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a model-independent approach. The TOTEM cross sections, extrapolated to a center-of-mass energy of $\sqrt{s} =$ 1.96 TeV, are compared with the D0...
Recently, a statistically significant signal for the observation of the odderon has been published in EPJ C, that reported an Odderon signal of at least 6.26 sigma, based on a scaling analysis of the differential cross-sections of elastic pp and pbarp scattering in the TeV energy range [1]. The D0 and TOTEM collaborations reported an at least 5.2 sigma Odderon signal from a comparison of the...
We present recent BFKL phenomenological studies for several novel probes that have been proposed for the LHC and different collider environments. Since that the typical BFKL observables at the LHC are the azimuthal angle $\phi$ correlations of tagged particles in the final state, which are separated in rapidity, a specific attention has been drawn to the behaviour of the so-called azimuthal...
We use a recently proposed formalism which includes both small and large x gluons of a target nucleus (or proton) to calculate the photon-parton production cross section. This allows one to investigate azimuthal angular correlations between the produced photon and parton from low to high p_t, as well as the forward-backward rapidity correlations between the them.
