Sigma baryon

The Sigma baryons are a family of subatomic hadron particles which have a +2, +1 or −1 elementary charge or are neutral. They are baryons containing three quarks: two up and/or down quarks, and one third quark, which can be either a strange (symbols Σ+, Σ0, Σ−), a charm (symbols Σ++
c, Σ+
c, Σ0
c), a bottom (symbols Σ+
b, Σ0
b, Σ−
b) or a top (symbols Σ++
t, Σ+
t, Σ0
t) quark. However, the top Sigmas are not expected to be observed as the Standard Model predicts the mean lifetime of top quarks to be roughly 6975500000000000000♠5×10⁻²⁵ s. This is about 20 times shorter than the timescale for strong interactions, and therefore it does not form hadrons.

List

The symbols encountered in these lists are: I (isospin), J (total angular momentum), P (parity), u (up quark), d (down quark), s (strange quark), c (charm quark), t (top quark), b (bottom quark), Q (charge), B (baryon number), S (strangeness), C (charmness), B′ (bottomness), T (topness), as well as other subatomic particles (hover for name).

Track listing

Hardcore (electronic dance music genre)

Hardcore, formerly called hardcore techno, is a subgenre of electronic dance music that originated in the Netherlands from the emergent raves in the 1990s. Its subgenres are usually distinct from other electronic dance music genres by faster tempos (160 to 200 BPM or more), the intensity of the kicks and the synthesized bass (in some subgenres), the rhythm and the atmosphere of the themes (sometimes violent), the usage of saturation and experimentation close to that of industrial dance music.

History

1970s

To understand the emergence of hardcore one has to go back to the 1970s, to find signs of hard electronic dance music within industrial music. Groups such as Throbbing Gristle, Coil, Cabaret Voltaire, SPK, Foetus and Einstürzende Neubauten produced music using a wide range of electronic instruments. The message diffused by industrial was then very provocative. Some of the musical sounds and experimentation of industrial have directly influenced hardcore since the beginning of the movement.

Hard Core (Lil' Kim album)

Hard Core is the debut studio album by American rapper Lil' Kim; it was released on November 12, 1996 by Undeas Recordings and Big Beat Records. The album was notable for its overt raunchy sexual tone and Kim's lyrical delivery, which was praised by music critics shortly after its release.

Hard Core debuted at number eleven on the U.S. Billboard 200, and number three on Billboard's Top R&B Albums, selling 78,000 copies in its first week of release, and reached the top ten of the Canadian Albums Chart. In the United States, Hard Core was certified double platinum by the RIAA, and is considered by many a classic hip hop album.

Background

After making her debut recording appearance on Junior M.A.F.I.A.'s Conspiracy album, Lil' Kim appeared on records by artists such as Mona Lisa, The Isley Brothers, and Total. With recording her debut album, Hard Core was principally recorded at Manhattan-based studio, The Hit Factory, in New York City. Working with a number of producers, including Sean "Puff Daddy" Combs and Jermaine Dupri, the album featured edgy hardcore rap and explicit sexuality, as the title suggested, which at the time were two territories that had long been the province of male rappers. The album was originally titled "Queen Bee".

Oficial Factor

Cesar Caballero (born November 25, 1977) is a Mexican luchador enmascarado, or masked professional wrestler. Working under the ring name Oficial Factor, he appears for the Mexican professional wrestling promotion International Wrestling Revolution Group (IWRG) as a part of the Los Oficiales Elite group alongside Oficial Rayan and Oficial Spartan. Caballero previously worked under a number of other ring names including Mega, but they are not officially acknowledged, as the enmascarado character is promoted as a separate entity from his previous characters, which is often the case when a Mexican wrestler adopts a new masked character.

Professional wrestling career

In Lucha Libre it is traditional to keep the true identify of a masked wrestler a secret, not revealing their real names and oftentimes not revealing what previous ring names they have competed under. Caballero worked as "Mega" from 1998 as a low card masked wrestler
