A pair of new colored particles produced near the threshold can form a bound state and then annihilate into standard model particles. In this paper we show how the bound state signals can distinguish between two scenarios that have similar particle content and interactions but different spins, such as the minimal supersymmetric standard model (MSSM) and universal extra dimensions (UED). We find, for example, that bound states of KK gluons (KK gluonia) have an order of magnitude larger cross… 

Probing colored particles with photons, leptons, and jets

A bstractIf pairs of new colored particles are produced at the Large Hadron Collider, determining their quantum numbers, and even discovering them, can be non-trivial. We suggest that valuable

Resonances from QCD bound states and the 750 GeV diphoton excess

A bstractPair production of colored particles is in general accompanied by production of QCD bound states (onia) slightly below the pair-production threshold. Bound state annihilation leads to

Gluino-squark production at the LHC: the threshold

A bstractAn analysis of the cross section for hadronic production of gluino-squark pairs close to threshold is presented. Within the framework of non-relativistic QCD a significant enhancement

Effects of QCD bound states on dark matter relic abundance

A bstractWe study scenarios where there exists an exotic massive particle charged under QCD in the early Universe. We calculate the formation and dissociation rates of bound states formed by pairs of

Exotic colored scalars at the LHC

A bstractWe study the phenomenology of exotic color-triplet scalar particles X with charge |Q| = 2/3, 4/3, 5/3, 7/3, 8/3 and 10/3. If X is an SU(2)W-non-singlet, mass splitting within the multiplet

Simplified phenomenology for colored dark sectors

A bstractWe perform a general study of the relic density and LHC constraints on simplified models where the dark matter coannihilates with a strongly interacting particle X. In these models, the dark

Interpreting a 750 GeV diphoton resonance

A bstractWe discuss the implications of the significant excesses in the diphoton final state observed by the LHC experiments ATLAS and CMS around a diphoton invariant mass of 750 GeV. The

Colorful Twisted Top Partners and Partnerium at the LHC

A bstractIn scenarios that stabilize the electroweak scale, the top quark is typically accompanied by partner particles. In this work, we demonstrate how extended stabilizing symmetries can yield

Topics on Hadron Collider Physics

In this dissertation we present four techniques that could be used at the Large Hadron Collider (LHC) to improve the e ciency with which collected data is utilized, and to help detect signals of

Light stop NLSPs at the Tevatron and LHC

How light can the stop be given current experimental constraints? Can it still be lighter than the top? In this paper, we study this and related questions in the context of gauge-mediated

Annihilation decays of bound states at the LHC

At the Large Hadron Collider, heavy particles may be produced in pairs close to their kinematic threshold. If these particles have strong enough attractive interactions they may form bound states.

Testing gluino spin with three-body decays

We examine the possibility of distinguishing a supersymmetric gluino from a Kaluza-Klein gluon of universal extra dimensions (UED) at the Large Hadron Collider (LHC). We focus on the case when all

Spin measurements in cascade decays at the LHC

We systematically study the possibility of determining the spin of new particles after their discovery at the LHC. We concentrate on angular correlations in cascade decays. Motivated by constraints

Color octet scalar bound states at the LHC

One possible extension of the standard model scalar sector includes $SU(2{)}_{L}$ doublet scalars that are color octets rather than singlets. We focus on models in which the couplings to fermions are

Bound states of two gluinos at the Fermilab Tevatron and CERN LHC.

It is shown that existing and future colliders imply a realistic chance of observing gluinonium as a narrow peak in the two-jet invariant mass spectrum, which implies a relatively accurate measure of the gluino mass, which is dicult to determine by other means.

Diphoton decays of stoponium at the CERN Large Hadron Collider

If the lighter top squark has no kinematically allowed two-body decays that conserve flavor, then it will form hadronic bound states. This is required in models that are motivated by the

Once new particles are discovered at the LHC and their masses are measured, it will be of crucial importance to determine their spin, in order to identify the underlying new physics model. We
