We propose a new technique for determining the spin of new massive particles that might be discovered at the Large Hadron Collider. The method relies on pair-production of the new particles in a kinematic regime where the vector boson fusion production of color singlets is enhanced. For this regime, we show that the distribution of the leading jets as a function of their relative azimuthal angle can be used to distinguish spin-0 from spin-$ \frac{1}{2} $ particles. We illustrate this effect by…

Early spin determination at the LHC
If signals of new physics are discovered at the LHC it will be crucial to determine the spin structure of the new model. We discuss a method that can help to address this question with a low
Associated production evidence against Higgs impostors and anomalous couplings
There is still no proof that the new particle X recently discovered by the ATLAS and CMS Collaborations indeed has spin zero and positive parity, as confidently expected. We show here that the energy
Azimuthal correlation among jets produced in association with a bottom or top quark pair at the LHC
A bstractAngular correlation of jets produced in association with a massive scalar, vector or tensor boson is crucial in the determination of their spin and CP properties. We study jet angular
Compressed SUSY search at the 13 TeV LHC using kinematic correlations and structure of ISR jets
A bstractThe LHC search for nearly degenerate gluinos and neutralinos, which can occur, for example, in SUSY axion models, is limited by the reduced missing transverse momentum and effective mass in
Top squark with mass close to the top quark
The most natural supersymmetric solution to the hierarchy problem prefers the scalar top partner to be close in mass to the top quark. Experimental searches exclude top squarks across a wide range of

We investigate scenarios in which dark matter interacts with the Standard Model primarily through electroweak gauge bosons. We employ an effective field theory framework wherein the Standard Model

For a given E_{T} data set and mediator model, it is shown that one can differentiate a certain dark matter-mediator interaction from another through spectral decomposition.
