The Standard Model of particle physics has a number of asymmetries suggestive of a more fundamental theory, where the symmetries are restored. If the symmetry breaking scale is the electroweak scale, new Higgs bosons beyond that of the Standard Model could be observed at the Tevatron. Recent Tevatron searches have set the most stringent limits on new Higgs bosons in a variety of models.

We report on results obtained at the Tevatron by the CDF and D0 collaborations up to June 2008 (2.4 fb-1), on searches for standard model (SM) Higgs bosons having a high mass (135-200 GeV). High mass Higgs bosons decay dominantly in WW and the presented searches are performed in the leptonic decay modes of the W's. Both direct production (ppbar -> H) and associated production (ppbar -> WH) are studied and eventually combined with all channels available at the Tevatron. Prospects for SM Higgs searches with the full projected Tevatron statistics are also given.

One of the highest priority physics goals for the upgraded Tevatron experiments, CDF and D0, is the search for the Higgs boson. We present the initial results from both experiments, based on 40--90 pb$^{-1}$ integrated luminosity, of Higgs searches in several final states, including $WH$ and $ZH$, $H\to WW$, and doubly-charged Higgs.
Various recent results of new particle searches at the Fermilab Tevatron are presented. No evidence is found for supersymmetric particles (chargino, gluino), leptoquark bosons and heavy gauge bosons in p-pbar collisions at sqrt{s} = 1.8 TeV. Excluded mass regions for each particle are determined.

Successful operation of the Large Hadron Collider has led to more than 1 fb^-1 of data recorded with both ATLAS and CMS detectors by summer of 2011. This large amount of data has allowed to perform numerous searches for rare processes beyond the Standard Model, many of which are competitive with previous searches performed with the CDF and D0 detectors at the Tevatron. In this talk the most recent searches at the hadron colliders are reviewed.
The results for searches for Supersymmetry (SUSY) at the Tevatron Collider are summarized in this paper.

We present the non-standard model Higgs boson searches at both DO and CDF experiments. We concentrate on three topics, reported by DO and CDF recently: the searches for the minimal supersymmetric Higgs boson using pp--> hbb --> bbbb and pp --> hX --> tau tau X, and for long-lived doubly charged Higgs boson.
Quark-quark and quark-lepton searches for compositenss at the Fermilab Tevatron are summarized. These are of the contact-interaction variety where sqrt(s-hat) < the hypothesized mass scales, Lambda. Tevatron experiments limit a variety of compositeness phenomena in the range from 1.9 to 8.3 TeV.

We report on the event counts, kinematic distributions, and limits on selected model parameters.
The CDF and DØ experiments at the Tevatron are currently the only capable of searching for the Standard Model Higgs boson.

A summary of the present Standard Model Higgs search and measurement of top quark mass at the Tevatron are presented. The sensitivity of the present Higgs search at the Tevatron is limited by statistics to a cross section approximately two orders of magnitude higher than the predicted cross section for Standard Model Higgs production. With 30/fb of integrated luminosity, the Tevatron offers an unique potential discovery window for the Standard Model Higgs mass up to 130 GeV before LHC era. The study of top at the Tevatron has moved from discovery phase to one of characterizing its properties. …

No significant excess in data has been observed. We report limits on the parameters of several models, including: large extra dimension, compositeness, leptoquarks, and supersymmetry.
Search for non-Standard-Model Higgs bosons is one of the major goals of the ongoing Fermilab Tevatron run. Large data sets accumulated by the CDF and D0 experiments break new grounds in sensitivity.

This document is a brief review of some of the most relevant searches for Supersymmetry carried out at the Tevatron and the LHC collider experiments, until the end of August 2011. Different final states covering R-parity conserving and violating scenarios have been scrutinized and no significant deviation from the Standard Model has been observed. As a result, new limits on the Supersymmetry parameter space have been established.
