Gauge coupling unification without leptoquarks
Abstract We propose an interpretation of the gauge coupling unification scale which is not related to any new particle threshold. We revisit Grand Unified Theories and show that it is possible to completely eliminate the scalar as well as vector...

Mono-jet signatures of gluphilic scalar dark matter
Abstract A gluphilic scalar dark matter (GSDM) model has recently been proposed as an interesting vision for WIMP dark matter communicating dominantly with the Standard Model via gluons. We discuss the collider signature of a hard jet recoiling...

Overlaps after quantum quenches in the sine-Gordon model
Abstract We present a numerical computation of overlaps in mass quenches in sine-Gordon quantum field theory using truncated conformal space approach (TCSA). To improve the cut-off dependence of the method, we use a novel running coupling definition ...

Revised conditions for MRI due to isorotation theorem
Abstract We re-analyze the physical conditions for Magneto-rotational Instability (MRI) within a steady axisymmetric stratified disk of plasma, in order to account for the so-called isorotation theory (the spatial profile of differential angular...

Measurement of the cross section for inclusive isolated-photon production in pp collisions at s = 13 TeV using the ATLAS detector
Abstract Inclusive isolated-photon production in pp collisions at a centre-of-mass energy of 13 TeV is studied with the ATLAS detector at the LHC using...

First measurement of proton's charge form factor at very low Q 2 with initial state radiation
Abstract We report on a new experimental method based on initial-state radiation (ISR) in e–p scattering, which exploits the radiative tail of the elastic peak to study the properties of electromagnetic processes and to extract the proton charge...

Reconciling threshold and subthreshold expansions for pion–nucleon scattering
Abstract Heavy-baryon chiral perturbation theory (ChPT) at one loop fails in relating the pion–nucleon amplitude in the physical region and for subthreshold kinematics due to loop effects enhanced by large low-energy constants. Studying the chiral...

The electromagnetic performance of the RD52 fiber calorimeter
Abstract The RD52 calorimeter is an instrument intended to detect both electromagnetic and hadronic showers, as well as muons, using the dual-readout principle. Scintillation and Cherenkov light provide the two signals which, in combination, allow...

Probing atmospheric mixing and leptonic CP violation in current and future long baseline oscillation experiments
Abstract We perform realistic simulations of the current and future long baseline experiments such as T2K, NOνA, DUNE and T2HK in order to determine their ultimate potential in probing neutrino oscillation parameters. We quantify the potential of...

Multilepton signals of gauge mediated supersymmetry breaking at the LHC
Abstract We investigate multilepton LHC signals arising from electroweak processes involving sleptons. We consider the framework of general gauge mediated supersymmetry breaking, focusing on models where the low mass region of the superpartner...

Free compact boson on branched covering of the torus
Abstract We have studied the partition function of a free compact boson on a n-sheeted covering of torus gluing along m branch cuts. It is interesting because when the branched cuts are chosen to be real, the partition function is related to the...

Energy helps accuracy: Electroweak precision tests at hadron colliders
Abstract We show that high energy measurements of Drell–Yan at the LHC can serve as electroweak precision tests. Dimension-6 operators, from the Standard Model Effective Field Theory, modify the high energy behavior of electroweak gauge boson...

Systematic effects on cross-section data derived from reaction rates at a cold neutron beam
Abstract The methodology to derive cross-section data from measurements in a cold neutron beam was studied. Mostly, capture cross-sections at thermal energy are derived relative to a standard cross-section, e.g. the cross-section of the 1H(n,γ),...

Quaternion based generalization of Chern–Simons theories in arbitrary dimensions
Abstract A generalization of Chern–Simons gauge theory is formulated in any dimension and arbitrary gauge group where gauge fields and gauge parameters are differential forms of any degree. The quaternion algebra structure of this formulation is...
